Is it possible to implement dynamic stiffness springs in a modal analysis?

fabrice.gloaguen over 2 years ago

I have a modal analysis to do (SOL103) but I am asked to introduce CBUSH elements with a dynamic stiffness. Is it possible ?

If yes I tried with PBUSHT but I have an error with the TABLED1. Anyone know how to do it please?
