1. I took the Tutorial 1 example STEP that comes with Elmer "pump_carter_sup.stp", imported it to FC. There I closed one of the holes by adding an additive cylinder: 2. Then i exported it to a STEP using STEP format 203 (maybe 214 works, but did not test.
For Elmer it is important that the STEP is a signle body, therefore I made the Fusion in FreeCAD.
3. I start Elmer and load the last project
4. in Elmer I go to menu Open and load the changed STEP
result: Elmer automatically remeshes it with its basic settings:
So you can see that the analysis settings are kept.
You have to reset the faces on which forces act because the new mesh will have another shape. (Toponaming is a general issue one cannot easily resolve )
Resetting all faces can become time consuming and that's why I wrote for optimizing geometries, FreeCAD is better. For a single model that you just analyze you are quicker with ElmerGUI directly. However, since our Elmer support is still basic, you often have no other chance than to use ElmerGUI.
