CrysMAS was developed for axial symmetry, which is the normal use case. But it can also simulate translational symmetry. In this case the geometry is treated in Cartesian coordinates (2D simulation, coordinates x, y) and extended infinitely in the third direction (z). No gradient is assumed in z-direction.
Note
Be sure to change the symmetry before you switch to Materials Mode, because symmetry has an impact on boundary conditions.
The default is axial symmetry. If you have to change it, proceed as follows:
