CPRESS is low but not zero. The mesh is very coarse for now so I assume that this output can be improved significantly once I refine the mesh.
In a 3D case I get a significant reaction moment (229088.3 Nmm) and I also get it in a 2D case in Abaqus.
How would you add resistance in my case ? Unfortunately, torsional springs aren’t available in CalculiX (Torsional Spring - SPRING2?). I could fix the rotation of the driven (larger) gear but I would like to simulate the actual motion. Fixing one gear will make it too stiff when compared with real operation.
Sure, here it is (from PrePoMax v1.3.5):
