Reply To: How to apply a stress as an initial load state ?

[dlooman]

The deformation appears to be quite extreme.  Make sure load ramping is in effect (KBC,0).  Perhaps you need to use more than 10 substeps to unload the forces associated with the prestress.  You said previously that the 2nd solution converged and you got a small stress, 0.25e-3Pa.  There are different types of non-convergence.  Perhaps you could paste the force convergence graph into the forum.
