I feel a novice in FEM.
This is my model:
I want to analyse its strength if an axis (purple) is placed as indicaded and presses downward.
I prepared two approaches, of which none succeeded so far.
- The one based on shells fails with a CalculiX execution error: "ERROR in gen3dnor: size of estimated shell normal in node 7 element 11790 is smaller than 1.e-10." I have no idea what I can do to avoid this error.
- The approach based on a solid yields a few meshing errors. To an extend that CalculiX doesn not like it.
Could somebody advise a suitable way forward? Improve the shells approach or the solid approach? Or otherwise?
Thanks for your consideration!
