My analysis is devided in 2 steps. At the first step the Bolt Pretension is applied and then locked on the second step. The Remote Force is applied on the second step. Can these two conditions be applied together? My analysis does not converge at the begining of the 2nd time step.

When I apply a Force (not remote) the analysis works.

Anyone had this problem before?

Check where the coordinate system that was created with the remote displacement is located. Is it where you expect?  You have one converged substep in step 2 that you can look at.   When you look at the to Newton-Raphson Residual Force plots, where is the maximum value?  Can you make smaller elements near that maximum?

Refining the mesh at the maximum of the Newton-Raphson values resolved the issue.

Thank you
