# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## Unreleased
### Changed
- `CXXFLAGS` are now passed to the linker
- Added this changelog
- Using absolute paths for environmental variables when running `scons test`
- Reorganized documentation layout
### Deprecated
- Python 2 support is discontinued. Version `v2.2.1` is the last PyPi build with
a Python 2 wheel.
## 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.
