Using duplication worked well for making changes to meshes, but didn't work as well when duplicating a simulation and then wanting to use a different mesh. When switching to a different mesh SimScale reported that the "topology changed" and then proceeded to throw away all "connections" between constraints, materials, contacts and loads and the mesh. It did this despite the new mesh being identical in structure to the old one and contained the exact same solids and faces, only the mesh "propteries" changed.
My simple test project has only 3 solids and 16 faces so this isn't too hard, but with a more compilcated project this would seem to be a big problem. Is there some other technique I need to use to make this process of converging on the mesh "quality" simpler?
