All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

v2.2.2 -- 2021-04-02

Added

• Entry-point tamaas defines a grouped CLI for examples/pipe_tools. Try executing tamaas surface -h from the command-line!

Changed

• CXXFLAGS are now passed to the linker
• Added this changelog
• Using absolute paths for environmental variables when running scons test
• Reorganized documentation layout
• Gave the build system a facelift (docs are now generated directly with SCons instead of a Makefile)

Deprecated

• Python 2 support is discontinued. Version v2.2.1 is the last PyPi build with a Python 2 wheel.
• The scripts in examples/pipe_tools have been replaced by the tamaas command

Fixed

• UVWDumper no longer imports mpi4py in sequential
• Compiling with different Thrust/FFTW backends

v2.2.1 -- 2021-03-02

Added

• Output registered fields and dumpers in print(model)
• Added operator[] to the C++ model class (for fields)
• Added traction and displacement properties to Python model bindings
• Added operators property to Python model bindings, which provides a dict-like access to registered operators
• Added shape and spectrum to properties to Python surface generator bindings
• Surface generator constructor accepts surface global shape as argument
• Choice of FFTW thread model

Changed

• Tests use /tmp for temporary files
• Updated dependency versions (Thrust, Pybind11)

Deprecated

• Most get___() and set___() in Python bindings have been deprecated. They will generate a DeprecationWarning.

Removed

• All legacy code

v2.2.0 -- 2020-12-31

Added

• More accurate function for computation of contact area
• Function to compute deviatoric of tensor fields
• MPI implementation
• Convenience hdf5toVTK function
• Readonly properties shape, global_shape, boundary_shape on model to give shape information

Changed

• Preprocessor defined macros are prefixed with TAMAAS_
• Moved tamaas.to_voigt to tamaas.compute.to_voigt

Fixed

• Warning about deprecated constructors with recent GCC versions
• Wrong computation of grid strides
• Wrong computation of grid sizes in views

v2.1.4 -- 2020-08-07

Added

• Possibility to generate a static libTamaas
• C++ implementation of DFSANE solver
• Allowing compilation without OpenMP

Changed

• NetCDF dumper writes frames to a single file

Fixed

• Compatibility with SCons+Python 3

v2.1.3 -- 2020-07-27

Added

• Version number to TamaasInfo

Changed

• Prepending root directory when generating archive

v2.1.2 -- 2020-07-24

This release changes some core internals related to discrete Fourier transforms
for future MPI support.

Added

• Caching CXXFLAGS in SCons build
• SCons shortcut to create code archive
• Test of the elastic-plastic contact solver
• Paraview data dumper (.pvd files)
• Compression for UVW dumper
• __contains__ and __iter__ Python bindings of model
• Warning message of possible overflow in Kelvin

Changed

• Simplified tamaas_info.cpp, particularly the diff part
• Using a new class FFTEngine to manage discrete Fourier transforms. Plans are re-used as much as possible with different data with the same shape. This is in view of future MPI developments
• Redirecting I/O streams in solve functions so they can be used from Python (e.g. in Jupyter notebooks)
• Calling initialize() and finalize() is no longer necessary

Fixed

• Convergence issue with non-linear solvers
• Memory error in volume potentials

v2.1.1 -- 2020-04-22

Added

• SCons shortcut to run tests

Fixed

• Correct RPATH for shared libraries
• Issues with SCons commands introduced in v2.1.0
• Tests with Python 2.7

v2.1.0 -- 2020-04-17

Added

• SCons shortcuts to build/install Tamaas and its components
• Selection of integration method for Kelvin operator
• Compilation option to remove the legacy part of Tamaas
• NetCDF dumper

Fixed

• Link bug with clang
• NaNs in Kato saturated solver

v2.0.0 -- 2019-11-11

First public release. Contains relatively mature elastic-plastic contact code.
