In order to compile ``Akantu`` any compiler supporting fully C++14 should work.
In addition some libraries are required:
- CMake (>= 3.5.1)
- Boost (preprocessor and Spirit)
- zlib
- blas/lapack
For the python interface:
- Python (>=3 is recommended)
- pybind11 (if not present the build system will try to download it)
To run parallel simulations:
- MPI
- Scotch
To use the static or implicit dynamic solvers at least one of the following libraries is needed:
- MUMPS (since this is usually compiled in static you also need MUMPS dependencies)
- PETSc
To compile the tests and examples:
- Gmsh
- google-test (if not present the build system will try to download it)
Configuring and compilation
```````````````````````````
``Akantu`` is a `CMake <https://cmake.org/>`_ project, so to configure it, you can either
follow the usual way::
> cd akantu
> mkdir build
> cd build
> ccmake ..
[ Set the options that you need ]
> make
> make install
Using the python interface
--------------------------
You can install ``Akantu`` using pip::
> pip install akantu
You can then import the package in a python script as::
import akantu
The python API is similar to the C++ one, see :ref:`reference` . If you encouter any problem with the python interface, you are welcome to do a merge request or post an issue on `GitLab <https://gitlab.com/akantu/akantu/-/issues>`_ .
Tutorials with the python interface
```````````````````````````````````
To help getting started, several tutorials using the python interface
are available as notebooks with pre-installed version of ``Akantu`` on Binder.
The following tutorials are currently available:
`Plate whith a hole loaded <https://mybinder.org/v2/git/https%3A%2F%2Fgitlab.com%2Fakantu%2Ftutorials.git/HEAD?filepath=plate-hole/plate-hole.ipynb>`_
`Making your constitutive law in python <https://mybinder.org/v2/git/https%3A%2F%2Fgitlab.com%2Fakantu%2Ftutorials.git/HEAD?filepath=constitutive-laws/python_constitutive_law.ipynb>`_
Writing a ``main`` function
---------------------------
``Akantu`` first needs to be initialized. The memory management included in the
core library handles the correct allocation and de-allocation of vectors,
structures and/or objects. Moreover, in parallel computations, the
initialization procedure performs the communication setup. This is achieved by
the function :cpp:func:`initialize <akantu::initialize>` that is used as
follows::
#include "aka_common.hh"
#include "..."
using namespace akantu;
int main(int argc, char *argv[]) {
initialize("input_file.dat", argc, argv);
// your code ...
}
The :cpp:func:`initialize <akantu::initialize>` function takes the text inpute
file and the program parameters which can be parsed by ``Akantu`` in due form
(see sect:parser). Obviously it is necessary to include all files needed in
main. In this manual all provided code implies the usage of ``akantu`` as
namespace.
Compiling your simulation
-------------------------
The easiest way to compile your simulation is to create a ``cmake`` project by
putting all your code in some directory of your choosing. Then, make sure that
you have ``cmake`` installed and create a ``CMakeLists.txt`` file. An example of
a minimal ``CMakeLists.txt`` file would look like this:
.. code-block:: cmake
project(my_simu)
cmake_minimum_required(VERSION 3.0.0)
find_package(Akantu REQUIRED)
add_akantu_simulation(my_simu my_simu.cc)
Then create a directory called ``build`` and inside it execute ``cmake
-DAkantu_DIR=<path_to_akantu> -DCMAKE_BUILD_TYPE=RelWithDebInfo ..``. If you
installed ``Akantu`` in a standard directory such as ``/usr/local`` (using
``make install``), you can omit the ``-DAkantu_DIR=<path_to_akantu>`` option.
Other why ``path_to_akantu`` is either the folder where you built ``Akantu`` if
you did not do a ``make install``, or if you installed ``Akantu`` in
``CMAKE_INSTALL_PREFIX`` it is ``<CMAKE_INSTALL_PREFIX>/share/cmake/Akantu``.
Once ``cmake`` managed to configure and generate a ``makefile`` you can just do
``make``
.. _loading_mesh:
Creating and Loading a Mesh
---------------------------
In its current state, ``Akantu`` supports three types of meshes: Gmsh, Abaqus and
Diana. Once a :cpp:class:`akantu::Mesh` object is created with a given spatial
dimension, it can be filled by reading a mesh input file. The method
:cpp:func:`read <akantu::Mesh::read>` of the class :cpp:class:`Mesh
<akantu::Mesh>` infers the mesh type from the file extension. If a non-standard
file extension is used, the mesh type has to be specified. ::
- UInt spatial_dimension = 2;
+ Int spatial_dimension = 2;
Mesh mesh(spatial_dimension);
// Reading Gmsh files
mesh.read("my_gmsh_mesh.msh");
mesh.read("my_gmsh_mesh", _miot_gmsh);
The Gmsh reader adds the geometrical and physical tags as mesh data. The
-physical values are stored as a :cpp:type:`UInt <akantu::UInt>` data called
+physical values are stored as a :cpp:type:`Int <akantu::Int>` data called
``tag_0``, if a string name is provided it is stored as a ``std::string`` data
-named ``physical_names``. The geometrical tag is stored as a :cpp:type:`UInt
-<akantu::UInt>` data named ``tag_1``.
+named ``physical_names``. The geometrical tag is stored as a :cpp:type:`Int
+<akantu::Int>` data named ``tag_1``.
Using Arrays
------------
Data in ``Akantu`` can be stored in data containers implemented by the
:cpp:class:`akantu::Array` class. In its most basic usage, the :cpp:class:`Array
<akantu::Array>` class implemented in \akantu is similar to the ``std::vector``
class of the Standard Template Library (STL) for C++. A simple :cpp:class:`Array
<akantu::Array>` containing a sequence of ``nb_element`` values (of a given
type) can be generated with::
Array<type> example_array(nb_element);
where ``type`` usually is :cpp:type:`Real <akantu::Real>`, :cpp:type:`Int
<akantu::Int>`, :cpp:type:`UInt <akantu::UInt>` or ``bool``. Each value is
associated to an index, so that data can be accessed by typing::
auto & val = example_array(index);
``Arrays`` can also contain tuples of values for each index. In that case, the
number of components per tuple must be specified at the :cpp:class:`Array
<akantu::Array>` creation. For example, if we want to create an
:cpp:class:`Array <akantu::Array>` to store the coordinates (sequences of three
values) of ten nodes, the appropriate code is the following::
with :math:`\vec{Q}^{\text{ext}}` the consistent heat generated.
Using the Heat Transfer Model
-----------------------------
A material file name has to be provided during initialization.
Currently, the :cpp:class:`HeatTransferModel <akantu::HeatTransferModel>` object uses dynamic analysis
with an explicit time integration scheme. It can simply be created
like this
.. code-block:: c++
HeatTransferModel model(mesh, spatial_dimension);
while an existing mesh has been used (see \ref{sect:common:mesh}).
Then the model object can be initialized with:
.. code-block:: c++
model.initFull()
This function will load the material properties, and allocate / initialize the nodes and element :cpp:class:`Arrays <akantu::Array>`
More precisely, the heat transfer model contains 4 :cpp:class:`Arrays <akantu::Array>`:
- **temperature** contains the nodal temperature :math:`T` (zero by default after the initialization).
- **temperature_rate** contains the variations of temperature :math:`\dot{T}` (zero by default after the initialization).
- **blocked_dofs** contains a Boolean value for each degree of freedom specifying whether the degree is blocked or not. A Dirichlet boundary condition (:math:`T_d`) can be prescribed by setting the **blocked_dofs** value of a degree of freedom to ``true``. The **temperature** and the **temperature_rate** are computed for all degrees of freedom where the **blocked_dofs** value is set to ``false``. For the remaining degrees of freedom, the imposed values (zero by default after initialization) are kept.
- **external_heat_rate** contains the external heat generations. :math:`\vec{Q^{ext}}` on the nodes.
- **internal_heat_rate** contains the internal heat generations. :math:`\vec{Q^{int}} = -\mat{K} \cdot \vec{T}` on the nodes.
Only a single material can be specified on the domain. A material text file (*e.g.* material.dat) provides the material properties as follows:
.. code-block:: python
model heat_transfer_model [
capacity = %\emph{XXX}%
density = %\emph{XXX}%
conductivity = [%\emph{XXX}% ... %\emph{XXX}%]
]
where the ``capacity`` and ``density`` are scalars, and the ``conductivity`` is specified as a :math:`3\times 3` tensor.
Explicit Dynamic
----------------
The explicit time integration scheme in ``Akantu`` uses a lumped capacity
matrix :math:`\mat{C}` (reducing the computational cost, see Chapter :ref:`sect-smm`).
This matrix is assembled by distributing the capacity of each element onto its nodes. Therefore, the resulting :math:`\mat{C}` is a diagonal matrix stored in the ``capacity`` :cpp:class:`Array <akantu::Array>` of the model.
.. code-block:: c++
model.assembleCapacityLumped();
.. note::
Currently, only the explicit time integration with lumped capacity
matrix is implemented within ``Akantu``.
The explicit integration scheme is *Forward Euler* :cite:`curnier92a`.
- Predictor: :math:`\vec{T}_{n+1} = \vec{T}_{n} + \Delta t \dot{\vec{T}}_{n}`
This model contains at least the following :cpp:class:`Arrays <akantu::Arrays>`:
- **blocked_dofs** contains a Boolean value for each degree of
freedom specifying whether that degree is blocked or not. A
Dirichlet boundary condition can be prescribed by setting the
**blocked_dofs** value of a degree of freedom to
``true``. The **displacement** is computed for all degrees
of freedom for which the **blocked_dofs** value is set to
``false``. For the remaining degrees of freedom, the imposed
values (zero by default after initialization) are kept.
- **displacement_rotation** contains the generalized displacements (*i.e.* displacements and rotations) of all degrees of freedom. It can be either a computed displacement for free degrees of freedom or an imposed displacement in case of blocked ones (:math:`\vec{u}` in the following).
- **external_force** contains the generalized external forces (forces and moments) applied to the nodes (:math:`\vec{f_{\st{ext}}}` in the following).
- **internal_force** contains the generalized internal forces (forces and moments) applied to the nodes (:math:`\vec{f_{\st{int}}}` in the following).
An example to help understand how to use this model will be presented in the
next section.

Initialization
``````````````
The easiest way to initialize the structural mechanics model is:
.. code-block:: c++
model.initFull();
The method :cpp:class:`initFull <akantu::StructuralMechanicsModel::initFull>` computes the shape
functions, initializes the internal vectors mentioned above and allocates the
memory for the stiffness matrix, unlike the solid mechanics model, its default
argument is ``_static``.
Material properties are defined using the :cpp:class:`StructuralMaterial
<akantu::StructuralMaterial>` structure described in
:numref:`tab-structmechmod-strucmaterial`. Such a definition could, for
instance, look like
.. code-block:: c++
StructuralMaterial mat1;
mat.E=3e10;
mat.I=0.0025;
mat.A=0.01;
.. _tab-structmechmod-strucmaterial:
.. table:: Material properties for structural elements defined in the class :cpp:class:`StructuralMaterial <akantu::StructuralMaterial>`.
:align: center

Field Description

``E`` Young's modulus
``A`` Cross section area
``I`` Second cross sectional moment of inertia (for 2D elements)
``Iy`` ``I`` around beam :math:`y`--axis (for 3D elements)
``Iz`` ``I`` around beam :math:`z`--axis (for 3D elements)
``GJ`` Polar moment of inertia of beam cross section (for 3D elements)
====== ======
Materials can be added to the model's ``element_material`` vector using
.. code-block:: c++
model.addMaterial(mat1);
They are successively numbered and then assigned to specific elements.
As explained before, the Dirichlet boundary conditions are applied through the
array **blocked_dofs**. Two options exist to define Neumann conditions.
If a nodal force is applied, it has to be directly set in the array
**force_momentum**. For loads distributed along the beam length, the
method :cpp:class:`computeForcesFromFunction <akantu::computeForcesFromFunction>` integrates them into nodal forces. The
method takes as input a function describing the distribution of loads along the
beam and a functor :cpp:class:`BoundaryFunctionType <akantu::BoundaryFunctionType>` specifing if the function is expressed in the local coordinates (``_bft_traction_local``) or in the
The :cpp:class:`StructuralMechanicsModel <akantu::StructuralMechanicsModel>` class can perform static analyses of structures. In this case, the equation to solve is the same as for the :cpp:class:`SolidMechanicsModel <akantu::SolidMechanicsModel>` used for static analyses
.. math:: \mat{K} \vec{u} = \vec{f_{\st{ext}}}~,
:label: eqn-structmechmod-static
where :math:`\mat{K}` is the global stiffness matrix, :math:`\vec{u}` the
generalized displacement vector and :math:`\vec{f_{\st{ext}}}` the vector of

is used. First a model has to be created and initialized.
.. code-block:: c++
StructuralMechanicsModel model(mesh);
model.initFull();
- :cpp:func:`model.initFull <akantu::StructuralMechanicsModel::initFull>` initializes all
internal vectors to zero.
Once the model is created and initialized, the boundary conditions can be set as explained in Section :ref:`sect:structMechMod:boundary`. Boundary conditions will prescribe the external forces or moments for the free degrees of freedom :math:`\vec{f_{\st{ext}}}` and displacements or rotations for the others. To completely define the system represented by equation (:eq:`eqn-structmechmod-static`), the global stiffness matrix :math:`\mat{K}` must be assembled.
.. code-block:: c++

\section{Compiling \akantu}
\akantu is a \code{cmake} project, so to configure it, you can either
follow the usual way:
\begin{command}
> cd akantu
> mkdir build
> cd build
> ccmake ..
[ Set the options that you need ]
> make
> make install
\end{command}
\noindent Or, use the \code{Makefile} we added for your convenience to
handle the \code{cmake} configuration
\begin{command}
> cd akantu
> make config
> make
> make install
\end{command}
\noindent All the \akantu options are documented in Appendix
\ref{app:package-dependencies}.
\section{Writing a \texttt{main} Function\label{sect:common:main}}
\label{sec:writing_main}
First of all, \akantu needs to be initialized. The memory management
included in the core library handles the correct allocation and
de-allocation of vectors, structures and/or objects. Moreover, in
parallel computations, the initialization procedure performs the
communication setup. This is achieved by a pair of functions
(\code{initialize} and \code{finalize}) that are used as follows:
\begin{cpp}
#include "aka_common.hh"
#include "..."
using namespace akantu;
int main(int argc, char *argv[]) {
initialize("input_file.dat", argc, argv);
// your code
...
finalize();
}
\end{cpp}
The \code{initialize} function takes the text inpute file and the program
parameters which can be parsed by \akantu in due form (see \ref{sect:parser}).
Obviously it is necessary to include all files needed in main. In this manual
all provided code implies the usage of \code{akantu} as namespace.
\section{Creating and Loading a Mesh\label{sect:common:mesh}}
In its current state, \akantu supports three types of meshes: Gmsh~\cite{gmsh},
Abaqus~\cite{abaqus} and Diana~\cite{diana}. Once a \code{Mesh} object is
created with a given spatial dimension, it can be filled by reading a mesh input file.
The method \code{read} of the class \code{Mesh} infers the mesh type from the file extension. If a non-standard file extension is used, the mesh type has to be specified.
\begin{cpp}
-UInt spatial_dimension = 2;
+Int spatial_dimension = 2;
Mesh mesh(spatial_dimension);
// Reading Gmsh files
mesh.read("my_gmsh_mesh.msh");
mesh.read("my_gmsh_mesh", _miot_gmsh);
// Reading Abaqus files
mesh.read("my_abaqus_mesh.inp");
mesh.read("my_abaqus_mesh", _miot_abaqus);
// Reading Diana files
mesh.read("my_diana_mesh.dat");
mesh.read("my_diana_mesh", _miot_diana);
\end{cpp}
The Gmsh reader adds the geometrical and physical tags as mesh data. The physical
-values are stored as a \code{UInt} data called \code{tag\_0}, if a string
+values are stored as a \code{Int} data called \code{tag\_0}, if a string
name is provided it is stored as a \code{std::string} data named
-\code{physical\_names}. The geometrical tag is stored as a \code{UInt} data named
+\code{physical\_names}. The geometrical tag is stored as a \code{Int} data named
\code{tag\_1}.
The Abaqus reader stores the \code{ELSET} in ElementGroups and the \code{NSET}
in NodeGroups. The material assignment can be retrieved from the
\code{std::string} mesh data named \code{abaqus\_material}.
% \akantu supports meshes generated with Gmsh~\cite{gmsh}, a free
% software available at \url{http://geuz.org/gmsh/} where a detailed
% documentation can be found. Consequently, this manual will not provide
% Gmsh usage directions. Gmsh outputs meshes in \code{.msh} format that can be read
% by \akantu. In order to import a mesh, it is necessary to create
% a \code{Mesh} object through the following function calls:
% \begin{cpp}
-% UInt spatial_dimension = 2;
+% Int spatial_dimension = 2;
% Mesh mesh(spatial_dimension);
% \end{cpp}
% The only parameter that has to be specified by the user is the spatial
% dimension of the problem. Now it is possible to read a \code{.msh} file with
% a \code{MeshIOMSH} object that takes care of loading a mesh to memory.
% This step is carried out by:
% \begin{cpp}
% mesh.read("square.msh");
% \end{cpp}
% where the \code{MeshIOMSH} object is first created before being
% used to read the \code{.msh} file. The mesh file name as well as the \code{Mesh}
% object must be specified by the user.
% The \code{MeshIOMSH} object can also write mesh files. This feature
% is useful to save a mesh that has been modified during a
% simulation. The \code{write} method takes care of it:
% \begin{cpp}
% mesh_io.write("square_modified.msh", mesh);
% \end{cpp}
% which works exactly like the \code{read} method.
% \akantu supports also meshes generated by
% DIANA (\url{http://tnodiana.com}), but only in reading mode. A similar
% procedure applies where the only
% difference is that the \code{MeshIODiana} object should be used
% instead of the \code{MeshIOMSH} one. Additional mesh readers can be
% introduced into \akantu by coding new \code{MeshIO} classes.
\section{Using \texttt{Arrays}}
Data in \akantu can be stored in data containers implemented by
the \code{Array} class. In its most basic usage, the \code{Array} class
implemented in \akantu is similar to the \code{vector} class of
the Standard Template Library (STL) for C++. A simple \code{Array}
containing a sequence of \code{nb\_element} values (of a given type) can be generated with:
\begin{cpp}
Array<type> example_array(nb_element);
\end{cpp}
where \code{type} usually is \code{Real}, \code{Int}, \code{UInt} or
\code{bool}. Each value is associated to an index, so that data can be
accessed by typing:
\begin{cpp}
auto & val = example_array(index)
\end{cpp}
\code{Arrays} can also contain tuples of values for each index. In
that case, the number of components per tuple must be specified at the
\code{Array} creation. For example, if we want to create an
\code{Array} to store the coordinates (sequences of three values) of
In this case the $x$ position of the eighth node number will be given by
\code{position(7, 0)} (in C++, numbering starts at 0 and not
1). If the number of components for the sequences is not specified, the
default value of 1 is used.
Here is a list of some basic operations that can be performed on \code{Array}:
\begin{itemize}
\item \code{resize(size)} change the size of the \code{Array}.
\item \code{clear()} set all entries of the \code{Array} to zero.
\item \code{set(t)} set all entries of the \code{Array} to \code{t}.
\item \code{copy(const Array<T> $\&$ other)} copy another \code{Array} into the current one. The two \code{Array} should have the same number of components.
\item \code{push$\_$back(tuple)} append a tuple with the correct number of components at the end of the \code{Array}.
\item \code{erase(i) erase the value at the i-th position.}
\item \code{find(value)} search \code{value} in the current \code{Array}. Return position index of the first occurence or $-1$ if not found.
\item \code{storage()} Return the address of the allocated memory of the \code{Array}.
\end{itemize}
\subsection{\texttt{Arrays} iterators}
It is very common in \akantu to loop over arrays to perform a specific
treatment. This ranges from geometric calculation on nodal quantities
to tensor algebra (in constitutive laws for example).
The \code{Array} object has the possibility to request iterators
in order to make the writing of loops easier and enhance readability.
For instance, a loop over the nodal coordinates can be performed like:
\begin{cpp}
//accessing the nodal coordinates Array (spatial_dimension components)
const auto & nodes = mesh.getNodes();
//creating the iterators
auto it = nodes.begin(spatial_dimension);
auto end = nodes.end(spatial_dimension);
for (; it != end; ++it){
const auto & coords = (*it);
//do what you need
....
}
\end{cpp}
In that example, each \code{coords} is a \code{Vector<Real>} containing
geometrical array of size \code{spatial\_dimension} and the iteration is
conveniently performed by the \code{Array} iterator.
With the switch to \code{c++14} this can be also written as
\begin{cpp}
//accessing the nodal coordinates Array (spatial_dimension components)
const auto & nodes = mesh.getNodes();
for (const auto & coords : make_view(nodes, spatial_dimension) {
//do what you need
....
}
\end{cpp}
The \code{Array} object is intensively used to store second order
tensor values. In that case, it should be specified that the returned
object type is a matrix when constructing the iterator. This is done
when calling the \code{begin} function. For instance, assuming that we
have a \code{Array} storing stresses, we can loop over the stored
tensors by:
\begin{cpp}
//creating the iterators
auto it = stresses.begin(spatial_dimension, spatial_dimension);
auto end = stresses.end(spatial_dimension, spatial_dimension);
for (; it != end; ++it){
Matrix<Real> & stress = (*it);
//do what you need
....
}
\end{cpp}
In that last example, the \code{Matrix} objects are
A group of nodes is stored in \code{NodeGroup} objects.
They are quite simple objects which store the indexes
-of the selected nodes in a \code{Array<UInt>}.
+of the selected nodes in a \code{Array<Idx>}.
Nodes are selected by adding them when calling
\code{NodeGroup::add}. For instance you can select nodes
having a positive $X$ coordinate with the following code:
\begin{cpp}
const auto & nodes = mesh.getNodes();
auto & group = mesh.createNodeGroup("XpositiveNode");
for (auto && data : enumerate(make_view(nodes, spatial_dimension))){
auto node = std::get<0>(data);
const auto & position = std::get<1>(data);
if (position(0) > 0) group.add(node);
}
\end{cpp}
\subsection{The \texttt{ElementGroup} object}
A group of elements is stored in \code{ElementGroup} objects.
Since a group can contain elements of various types
the \code{ElementGroup} object stores indexes in
-a \code{ElementTypeMapArray<UInt>} object.
+a \code{ElementTypeMapArray<Idx>} object.
Then elements can be added to the group by calling \code{addElement}.
For instance, selecting the elements for which the barycenter of the nodes
has a positive $X$ coordinate can be made with:
\begin{cpp}
auto & group = mesh.createElementGroup("XpositiveElement");
Vector<Real> barycenter(spatial_dimension);
for(auto type : mesh.elementTypes()){
- UInt nb_element = mesh.getNbElement(type);
+ Int nb_element = mesh.getNbElement(type);
- for(UInt e = 0; e < nb_element; ++e) {
+ for(Int e = 0; e < nb_element; ++e) {
Element element{type, e, _not_ghost};
mesh.getBarycenter(element, barycenter);
if (barycenter(_x) > 0.) group.add(element);
}
}
\end{cpp}
\section{Compiling your simulation}
The easiest way to compile your simulation is to create a \code{cmake} project by putting all your code in some directory of your choosing. Then, make sure that you have \code{cmake} installed and create a \code{CMakeLists.txt} file. An example of a minimal \code{CMakeLists.txt} file would look like this:
\begin{cmake}
project(my_simu)
cmake_minimum_required(VERSION 3.0.0)
find_package(Akantu REQUIRED)
add_akantu_simulation(my_simu my_simu.cc)
\end{cmake}
%
Then create a directory called \code{build} and inside it execute \code{ccmake ..} which opens a configuration screen. If you installed \akantu in a standard directory such as \code{/usr/local} (using \code{make install}), you should be able to compile by hitting the \code{c} key, setting \code{CMAKE\textunderscore{}BUILD\textunderscore{}TYPE} to \code{Release}, hitting the \code{c} key again a few times and then finishing the configuration with the \code{g} key. After that, you can type \code{make} to build your simulation. If you change your simulation code later on, you only need to type \code{make} again.
If you get an error that \code{FindAkantu.cmake} was not found, you have to set the \code{Akantu\textunderscore{}DIR} variable, which will appear after dismissing the error message. If you built \akantu without running \code{make install}, the variable should be set to the \code{build} subdirectory of the \akantu source code. If you installed it in \code{\$PREFIX}, set the variable to \code{\$PREFIX/share/cmake/Akantu} instead.
with $\vec{Q}^{\text{ext}}$ the consistent heat generated.
\section{Using the Heat Transfer Model}
A material file name has to be provided during initialization.
Currently, the \code{HeatTransferModel} object uses dynamic analysis
with an explicit time integration scheme. It can simply be created
like this
\begin{cpp}
HeatTransferModel model(mesh, spatial_dimension);
\end{cpp}
while an existing mesh has been used (see \ref{sect:common:mesh}).
Then the model object can be initialized with:
\begin{cpp}
model.initFull()
\end{cpp}
This function will load the material
properties, and allocate / initialize the nodes and element \code{Array}s
More precisely, the heat transfer model contains 4 \code{Arrays}:
\begin{description}
\item[temperature] contains the nodal temperature $T$ (zero by default after the
initialization).
\item[temperature\_rate] contains the variations of temperature $\dot{T}$
(zero by default after the
initialization).
\item[blocked\_dofs] contains a Boolean value for each degree of
freedom specifying whether the degree is blocked or not. A Dirichlet
boundary condition ($T_d$) can be prescribed by setting the
\textbf{blocked\_dofs} value of a degree of freedom to \code{true}.
The \textbf{temperature} and the \textbf{temperature\_rate} are
computed for all degrees of freedom where the \textbf{blocked\_dofs}
value is set to \code{false}. For the remaining degrees of freedom,
the imposed values (zero by default after initialization) are kept.
\item[external\_heat\_rate] contains the external heat generations. $\vec{Q^{ext}}$
on the nodes.
\item[internal\_heat\_rate] contains the internal heat generations. $\vec{Q^{int}} = -\mat{K} \cdot \vec{T}$ on the nodes.
\end{description}
Only a single material can be specified on the domain.
A material text file (\eg material.dat) provides the material properties as follows:
\begin{cpp}
model heat_transfer_model [
capacity = %\emph{XXX}%
density = %\emph{XXX}%
conductivity = [%\emph{XXX}% ... %\emph{XXX}%]
]
\end{cpp}
where the \code{capacity} and \code{density} are scalars, and the \code{conductivity} is specified as a $3\times 3$ tensor.
\subsection{Explicit Dynamic}
The explicit time integration scheme in \akantu uses a lumped capacity
matrix $\mat{C}$ (reducing the computational cost, see Chapter \ref{sect:smm}).
This matrix is assembled by
distributing the capacity of each element onto its nodes. Therefore, the resulting $\mat{C}$ is a diagonal matrix stored in the \code{capacity} \code{Array} of the model.
\begin{cpp}
model.assembleCapacityLumped();
\end{cpp}
\index{HeatTransferModel!assembleCapacityLumped}
\note{Currently, only the explicit time integration with lumped capacity matrix
is implemented within \akantu.} The explicit integration scheme is \index{Forward Euler} \emph{Forward Euler}
\cite{curnier92a}.
\begin{itemize}
\item Predictor: $\vec{T}_{n+1} = \vec{T}_{n} + \Delta t \dot{\vec{T}}_{n}$
The text input file of a simulation should be precised using the method \code{initialize} which will instantiate the static \code{Parser} object of \akantu. This section explains how to manipulate \code{Parser} objects to input data in \akantu.
\begin{cpp}
int main(int argc, char *argv[]) {
initialize("input_files.dat", argc, argv);
...
\end{cpp}
\subsection{Akantu Parser}
\akantu file parser has a tree organization.
\begin{itemize}
\item \code{Parser}, the root of the tree, can be accessed using
\begin{cpp}
Parser & parser = getStaticParser();
\end{cpp}
\item \code{ParserSection}, branch of the tree, contains map a of sub-sections (\code{SectionType}, \code{ParserSection}) and a \code{ParserSection *} pointing to the parent section. The user section of the input file can directly be accessed by
\begin{cpp}
const ParserSection & usersect = getUserParser();
\end{cpp}
\item \code{ParserParameter}, the leaf of the tree, carries data of the input file which can be casted to the correct type with
\begin{cpp}
Real mass = usersect.getParameter("mass");
\end{cpp}
or used directly within an expression
\begin{cpp}
Real dead_weight = 9.81 * usersect.getParameterValue<Real>("mass");
\end{cpp}
\end{itemize}
\subsection{Grammar}
The structure of text input files consists of different sections containing a list of parameters. As example, the file parsed in the previous section will look like
\begin{cpp}
user parameters [
mass = 10.5
]
\end{cpp}
Basically every standard arithmetic operations can be used inside of input files as well as the constant \code{pi} and \code{e} and the exponent operator \code{\^{}}. Operations between \code{ParserParameter} are also possible with the convention that only parameters of the current and the parent sections are available. \code{Vector} and \code{Matrix} can also be read according to the \code{NumPy}\cite{numpy} writing convention (a.e. cauchy$\_$stress$\_$tensor = [[$\sigma_{xx}$, $\sigma_{xy}$],[$\sigma_{yx}$,$\sigma_{yy}$]]).
An example illustrating how to parse the following input file can be found in \code{example$\backslash$io$\backslash$parser$\backslash$example$\_$parser.cc}.
The input file should also be used to specify material characteristics (constitutive behavior and material properties). The dedicated material section is then read by \code{initFull} method of \code{SolidMechanicsModel} which initializes the different materials specified with the following convention:
\begin{cpp}
material %\emph{constitutive\_law}% %\emph{<optional flavor>}% [
name = $value$
rho = $value$
...
]
\end{cpp}
\index{Constitutive\_laws} where \emph{constitutive\_law} is the adopted
constitutive law, followed by the material properties listed one by line in the
bracket (\eg \code{name} and density \code{rho}). Some constitutive laws can
also have an \emph{optional flavor}. More information can be found in sections relative to material
constitutive laws \ref{sect:smm:CL} or in Appendix \ref{app:material-parameters}.
\section{Output data}
\subsection{Generic data}
In this chapter, we address ways to get the internal data in human-readable formats.
The models in \akantu handle data associated to the
mesh, but this data can be split into several \code{Arrays}. For example, the
data stored per element type in a \code{ElementTypeMapArray} is composed of as
many \code{Array}s as types in the mesh.
In order to get this data in a visualization software, the models contain a
object to dump \code{VTK} files. These files can be visualized in software such
as \code{ParaView}\cite{paraview}, \code{ViSit}\cite{visit} or \code{Mayavi}\cite{mayavi}.
The internal dumper of the model can be configured to specify which data fields
are to be written. This is done with the
\code{addDumpField}\index{I\/O!addDumpField} method. By default all the files
are generated in a folder called \code{paraview/}
\begin{cpp}
model.setBaseName("output"); // prefix for all generated files
model.addDumpField("displacement");
model.addDumpField("stress");
...
model.dump()
\end{cpp}
The fields are dumped with the number of components of the memory. For example, in 2D, the memory has
\code{Vector}s of 2 components, or the $2^{nd}$ order tensors with $2\times2$ components.
This memory can be dealt with \code{addDumpFieldVector}\index{I\/O!addDumpFieldVector} which always dumps
\code{Vector}s with 3 components or \code{addDumpFieldTensor}\index{I\/O!addDumpFieldTensor} which dumps $2^{nd}$
order tensors with $3\times3$ components respectively. The routines \code{addDumpFieldVector}\index{I\/O!addDumpFieldVector} and
\code{addDumpFieldTensor}\index{I\/O!addDumpFieldTensor} were introduced because of \code{ParaView} which mostly manipulate 3D data.
Those fields which are stored by quadrature point are modified to be seen in the
\code{VTK} file as elemental data. To do this, the default is to average the
values of all the quadrature points.
The list of fields depends on the models (for
\code{SolidMechanicsModel} see table~\ref{tab:io:smm_field_list}).
\begin{table}
\centering
\begin{tabular}{llll}
\toprule
key & type & support \\
\midrule
displacement & Vector<Real> & nodes \\

\bottomrule
\end{tabular}
\caption{List of dumpable fields for \code{SolidMechanicsModel}.}
\label{tab:io:smm_field_list}
\end{table}
\subsection{Cohesive elements' data}
Cohesive elements and their relative data can be easily dumped thanks
to a specific dumper contained in
\code{SolidMechanicsModelCohesive}. In order to use it, one has just
to add the string \code{"cohesive elements"} when calling each method
already illustrated. Here is an example on how to dump displacement
It is assumed that the arrays in the map have the same sizes as the element numbers in the mesh for element types of dimension \code{spatial\_dimension}.
\begin{cpp}
ElementTypeMapArray<Real> elem_data;
elem_data.initialize(mesh,
_nb_component = 1,
_with_nb_element = true);
mesh.addDumpFieldExternal("my_field", elem_data);
\end{cpp}
\end{itemize}
If some changes have to be applied on the data as for example a padding for
\code{ParaView} vectors, this can be done by using the
\item \code{getCelerity}:~The stability criterion of the explicit integration scheme depend on the fastest wave celerity~\eqref{eqn:smm:explicit:stabletime}. This celerity depend on the material, and therefore the value of this velocity should be defined in this method for each new material. By default, the fastest wave speed is the compressive wave whose celerity can be defined in~\code{getPushWaveSpeed}.
\end{itemize}
Once the declaration and implementation of the new material has been
completed, this material can be used in the user's example by including the header file:
\begin{cpp}
#include "material_XXX.hh"
\end{cpp}
For existing materials, as mentioned in Section~\ref{sect:smm:CL}, by
default, the materials are initialized inside the method
\code{initFull}. If a local material should be used instead, the
initialization of the material has to be postponed until the local
material is registered in the model. Therefore, the model is
initialized with the boolean for skipping the material initialization
Only at this point the material can be initialized:
\begin{cpp}
model.initMaterials();
\end{cpp}
A full example for adding a new damage law can be found in
\shellcode{\examplesdir/new\_material}.
\subsection{Adding a New Non-Local Constitutive Law}\index{Material!create a new non-local material}
In order to add a new non-local material we first have to add the local constitutive law in \akantu (see above). We can then add the non-local version of the constitutive law by adding the two files (\code{material\_XXX\_non\_local.hh} and \code{material\_XXX\_non\_local.cc}) where \code{XXX} is the name of the corresponding local material. The new law must inherit from the two classes, non-local parent class, such as the \code{MaterialNonLocal} class, and from the local version of the constitutive law, \textit{i.e.} \code{MaterialXXX}. It is therefore necessary to include the interface of those classes in the header file of your custom material and indicate the inheritance in the declaration of the class:
In the intialization of the non-local material we need to register the local quantity for the averaging process. In our example the internal field \emph{grad\_u\_nl} is the non-local counterpart of the gradient of the displacement field (\emph{grad\_u\_nl}):
\begin{cpp}
void MaterialXXXNonLocal::initMaterial() {
MaterialXXX::initMaterial();
MaterialNonLocal::initMaterial();
/// register the non-local variable in the manager
The function to register the non-local variable takes as parameters the name of the local internal field, the name of the non-local counterpart and the number of components of the field we want to average.
In the \emph{computeStress} we now need to compute all the quantities we want to average. We can then write a loop for the stress computation in the function \emph{computeNonLocalStresses} and then provide the constitutive law on each integration point in the function \emph{computeNonLocalStress}.
