Martin Diehl 29cbf1304b grain growth not maintained and has issues
the grain growth model is based on the Voronoi Implicit Interface Method
(https://doi.org/10.1016/j.jcp.2012.04.004). The last step in this
algorithm is the assignment of the new phase/material ID to the voxels
in the 'thick boundary' which is done with distance_transform_edt from
ndimage. This problem can have multiple solution and can lead to the
translation of grains.

In the original publication, the position of the boundary is calculated
with subvoxel resolution by solving the eikonal equation. The following
python packages might help:
https://pypi.org/project/eikonalfm
https://pypi.org/project/scikit-fmm

Martin Diehl b285702d84 functionality is availabe in grid_filters.py 2021-12-27 21:18:31 +01:00
Martin Diehl 96767e75a3 can be done directly in the python library:
P = damask.Orientation(lattice='cF').Schmid('slip')
sigma = np.array([[1,0,0],[0,0,0],[0,0,0]])
sigma_extended = np.broadcast_to(sigma.reshape(damask.util.shapeshifter(sigma.shape,P.shape)),
                                 P.shape)
tau = np.einsum('i...jk,i...jk->i...',sigma_extended,P)

Martin Diehl 0f6094890a simplified
damask.environment does not offer any advantage over os.environ for
variables. After 'root_dir' was removed, the whole module became
obsolete

Martin Diehl de1708b20a missing renames + better help 2020-12-08 00:36:41 +01:00
Martin Diehl 171d642dbd rename: Geom -> Grid 2020-12-04 07:50:47 +01:00
Martin Diehl 0fdefa5e78 renames:
after the rename of "grid" to "cell", the name cell should not be used
for the coordinates of the cell centers. In agreement with the names
x_p/u_p for point positions/displacements, now the "point" is used to
refer to the materialpoints (i.e. cell centers)

Additionally, "_node"/"_point" are now suffixes to
"coordinates"/"displacements".

Finally, "coords" is renamed to "coordinates"

Martin Diehl 198736a859 volume mismatch is unreliable
the volume of a deformed hexahedron is not properly defined, the
approximation error is in the order of the deviation from 1.0 (for
typical crystal plasticity cases)
