This setup ( dem_rheology_dry.zip) doesn’t work for me with 25.1.1:
Error 1100: The des search grid is too fine in the X-direction. The
maximum particle diameter is larger than the cell width:
MAX DIAM: 0.96000E-03
CELL WIDTH: 0.50000E-03
Decrease the values for DESGRIDSEARCH in the project settings.
