Load material data from DREAM3D file. Load DREAM.3D (HDF5) file.
The parts of homogenization and phase need to be added by the user. Data in DREAM.3D files can be stored per cell ('CellData')
and/or per grain ('Grain Data'). Per default, cell-wise data
is assumed.
damask.Grid.load_DREAM3D allows to get the corresponding geometry
for the grid solver.
Parameters Parameters
---------- ----------
fname : str fname : str
Filename of the DREAM.3D (HDF5) file. Filename of the DREAM.3D (HDF5) file.
grain_data : str
Name of the group (folder) containing grain-wise data. Defaults
to None, in which case cell-wise data is used.
cell_data : str
Name of the group (folder) containing cell-wise data. Defaults to 'CellData'.
cell_ensemble_data : str
Name of the group (folder) containing data of cell ensembles.
This group is used to inquire the name of the phases. If set to
'None', phases get numeric IDs. Defaults to 'CellEnsembleData'.
phases : str
Name of the dataset containing the phase ID (cell-wise or grain-wise).
Defaults to 'Phases'.
Euler_angles : str
Name of the dataset containing the crystallographic orientation as
Euler angles in radians (cell-wise or grain-wise). Defaults to 'EulerAngles'.
phase_names : str
Name of the dataset containing the phase names. It is not used if
cell_ensemble_data is set to 'None. Defaults to 'PhaseName'.
base_group : str base_group : str
Path to the group (folder) that contains the geometry (_SIMPL_GEOMETRY), Path to the group (folder) that contains geometry (_SIMPL_GEOMETRY),
and, optionally, the cell data. Defaults to None, in which case and grain- or cell-wise data. Defaults to None, in which case
it is set as the path that contains _SIMPL_GEOMETRY/SPACING. it is set as the path that contains _SIMPL_GEOMETRY/SPACING.
