Starting with Cyclic Symmetry:
We looked at one of your old issues (Cyclic symmetry) and those instructions (*CYCLIC SYMMETRY MODEL) and edited the Calculix Keywords in PPM according to that. However we couldn’t find proper settings. The file is “20260414_deformation_washer_15deg_cycl_sym”.
Without cyclic symmetry (just a cylindrical CS) we also recieved a weird displacement in z. We stopped this sim rather quick, but ultimately, the disc moved out of the symmetry planes. The file is “20260414_deformation_washer_15deg.pmx”.
Now to your previous answer: Do I understand correctly that ridig bodies are actually more like rigid surfaces? So I would make the two surfaces rigid, that have contact with the disc? Is a fine mesh still needed for those surfaces, when it cannot deform?
I couldnt find how to properly set the reference points (or what characteristics a proper ref point should have). However, I get this error message:
"Decascading the MPC’s
*ERROR in cascade: the DOF corresponding to
node 1 in direction 3 is detected on the
dependent side of a MPC and a SPC"
The file is “20260421_deformation_washer_quarter_rigid_body”.
