Non linear spring in NX Nastran 8.0

(OP)
Hello Everybody,

Does anyone can tell me how can be a non-linear (Force vs displ.) modeled in Nx Nastran 8.0? I need to include non linear spring in a 106 (or 601) simulation, and I know that Nastran allow to do that using the PBUSHT card. Unfortunately I didn't find any reference about that.

any other suggestion is well accepted!!

Thanks in advance!
