  Hello community,
  
  I am trying to solve a structural-mechanics problem. I created the geometry and mesh with APDL and added the boundary conditions (forces and displacements) as well.
  
  When I try to solve the problem, I get two (at least for me) cryptic error-messages. The first one:
  
  and after pressig "Proceed":
  
  After that, the program closes immediately.
  
  Do you have any suggestions, what could lead to this problem?
  
  Best Regards
