I'm working with pro/mechanica. When I apply some loads (forces), the analysis run fine, but when I try to apply moment it makes " fatal error". If "fem" menù is not selected I can't create the mesh, but I think analysis is a FEA analysis. It is different? Do you know some tutorials about? Thanks
loads in pro/mechanica

Hi,
It sounds like you are trying to apply moments to a solid body. This is not possible in any FE system (or in real life either). Mechanica should issue a warning that the load will be ignored, then if you carry on the solver tries to solve a static analysis without a load (or enforced displacement) and fails.
Mechanica FEM mode is for pre- and post-processing conventional h-element models for solving with Ansys or Nastran. Mechanica itself uses p-element technology and auto-meshes when the analysis is run. If you want to see the mesh, go to AutoGEM and create the p-element mesh. Alternatively, in result check the 'display element edges' tick-box to show the elements in results plots.
We have used 'Pro/Mechanica Structure Tutorial' by Roger Toogood to teach Mechanica. Another good book on FE in general is 'Designing Better Products using Finite Element Analysis' by Vince Adams and Abe Askenazi.
