Then I created plate 100mm x 100mm x 100mm In the part workbench I created a new object After reading your thread I thought I would try the same approach with your project. I got round this problem (I think) by embedding one object in another. During the course of the thread I discovered that FreeCAD FEM workbench doesn't seem to like "face to face" contact when running an analysis. Hi - Qualifier!- I am an FEM novice but received help from bernd, tschrader, and user1234 with a similar problem recently. How can I achieve an analysis of such an object? At least such a stripped down example should work. shell of 5mm which should result in a solid somehow) (I also tried to have the 0.9mm thickness for all objects for simplicity)īut. ![]() (I know that FreeCad can't mix solids and shell elements, so I created a shell for the solid cube as well. ![]() Let's simply model the tube as a solid and define the wallthickness as shell thickness in FEM module. ![]() Code: Select all 21:30:30 Running the Python command 'FEM_MeshNetgenFromShape' failed:įile "C:\Freecad\FreeCAD_3-Win-Conda_vc14.x-x86_64\Mod\Fem\femcommands\commands.py", line 638, in ActivatedĬannot add an object from another document to this groupTraceback (most recent call last):Ģ1:30:54 File "C:\Freecad\FreeCAD_3-Win-Conda_vc14.x-x86_64\Mod\Fem\femtaskpanels\task_solver_ccxtools.py", line 305, in write_input_file_handlerĢ1:30:54 if self.check_prerequisites_helper():Ģ1:30:54 File "C:\Freecad\FreeCAD_3-Win-Conda_vc14.x-x86_64\Mod\Fem\femtaskpanels\task_solver_ccxtools.py", line 322, in check_prerequisites_helperĢ1:30:54 File "C:\Freecad\FreeCAD_3-Win-Conda_vc14.x-x86_64\Mod\Fem\femtools\ccxtools.py", line 237, in update_objectsĢ1:30:54 Exception: FEM: no mesh object found in analysis.Ģ1:33:29 Count finite elements as sum of constraints: 27606Ģ1:33:29 Count finite elements of the finite element mesh: 27809Ģ1:33:29 ERROR: femelement_table != count_femelementsĢ1:33:29 Error in get_femelement_sets - > femelements_count_ok() failed!
