when defining the meshes for the fix wall/grad command in the "Physics Models" tab it is only possible to add one single mesh. Due to the fact that I imported several meshes in the "Meshes and Region" tab, I got an error during the simulation.
ERROR: Invalid configuration, mesh Cover should be used for either insertion, wall or massflow measurement
I think this error occurs because the remaining meshes are not called in this command.
I solved the problem easily by adding the other meshes in the input script.
Does the starter version only supports one insertion and one mesh with contact definitions?
