NX Nastran SOL 402 Fatal Message 9457 (NLSTPKIN)

Hello,

 

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.
