It's not a bug it's a feature. ATM FreeCAD FEM does not search for the group data inside the mesh. This is on my LongTermToDo. ATM we gone use GMSH to generate groups. That is why groups can only be used with GMSH mesh. That is why elmer FEM needs a GMSH mesh. That is why with groups one needs to remesh. I will close this. We may open a feature to extend the FEMMesh Python API in the regard of creating groups from an existing mesh by searchting the mesh for the approbriate data. It is not a big deal. Anything is there in either SMESH or FreeCAD FEM. Bernd |

We may add an print or message box after a change on a group as a hint for the user that he needs to remesh. I will leave the ticked open. bernd |
