I'm running crash simulations of vehicles against rigid elements (walls or other buildings modeled with shells and MAT_RIGID). Contacts between vehicle and shells are set with *CONTACT_AUTOMATIC_SURFACE_TO_SURFACE_MPP_ID with a friction of 0.6. The model run correctly but the graphic output has always an "invisible offset" between the shell surface and the vehcile (see image). This offset seems to be independent to the SECTION_SHELL thickness.
Anyone has a hint on how to solve this, i.e. to delete this offset?
