For the EJ and the SimpleFFT solver, the computational grid can be adjusted under the Grid tab if necessary.

Sometimes, grid lengths might be different in each direction, e.g., for Focused Ion Beam images, the grid size in Z-direction is often different from the size in X- and Y-directions. For example, a structure is sampled in a computational grid with different lengths in X- and Y-direction (e.g., ).

When the structure geometry is loaded in GeoDict, each grid cell gets assigned 1 voxel and the visual representation of the structure looks stretched. To correct this effect, select Boxels with, e.g., Length X = 1 µm and Length Y = 0.5 µm.
