HI
I attach a model of a metal bracket for which the calculation fails. I don’t understand where is the mistake
Thank you for your help.

  1. It’s better to enable Nlgeom for now and set Nonlinear to Yes for compression only constraint.
  2. Isn’t the spring stiffness for compression only constraints (90000000 N/mm) too large ? It converges with lower value.
  3. You can’t fix rotations directly for solid elements.
  4. The mesh should be refined in the thickness direction.
