# 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). ## 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 - The scripts in `examples/pipe_tools` have been replaced by the `tamaas` command ## Fixed - `UVWDumper` no longer imports `mpi4py` in sequential - Compiling with different Thrust/FFTW backends ## v2.2.1 -- 2021-03-02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.
