[0.1.22] - 2021.11.09

Added

• Add saving of VE phases to a VTK file.

Changed

• Add parameter RNG_seed to task generate_microstructure_seeds/random.

• Add implementation of task generate_volume_element method from_damask_input_files

Changed

• Use new output map options (volume_data, phase_data, field_data and grain_data) for reading results from a simulation.
• Remove methods that made use of the DAMASK command line scripts.
• Add orientations_use_max_precision parameter to task/methods: generate_volume_element/random_voronoi, generate_volume_element/random_voronoi_from_orientations, sample_texture/from_random, generate_microstructure_seeds/random and simulate_volume_element_loading/CP_FFT.

Added

• Add implementation of task generate_microstructure_seeds with method random_NEW to use DAMASK library functions instead of command line script which has been removed in DAMASK v3a2.

[0.1.15] - 2020.01.19

Added

• Add implementation of task modify_volume_element by method add_buffer_zones.

Fixed

• Include an euler_degrees bool dict item in orientations to signify if the dict item euler_angles is represented in degrees or radians.

[0.1.14] - 2020.01.11

Fixed

• Use pack=False in DAMASK's geom_obj.to_file to ensure consistent format of geometry file in function main.generate_volume_element_random_voronoi.

[0.1.13] - 2020.01.10

Changed

• Input and output mapper functions for writing/reading DAMASK microstructure seeds files have been updated to respect the unit_cell_alignment key of orientations.
