Recently i tried to run a Multi-Step nonlinear simulation in NX Nastran with Femap.
The model is about a drop test with a cover falling to the floor. When i run the simulation i get the following message from the F06 File.
Error in the advanced nonlinear module with IRET=2
I tried to find inside the Nastran documentation about what is this about but the only thing a found is that the IRET valur must be zero, if is greater than zero, then the solution will be ended.
I'm attaching a screenshot of the error message, i hope someone can help me.
