FEMAP + NASTRAN - DAMPER CBUSH1D

[DanCivil]

Dear Sirs,

I want to define a damper (force - velocity relationship) in FEMAP. So far I found the description of a CBUSH1D Element in the NASTRAN manual. Unfortuntately I can not find any possibility in FEMAP to use this kind of element.

What can I do ?

FYI We are using "FEMAP WITH NASTRAN NX 9.30".

thanks
Dan

Hi

Try the spring/damper element type. There is a "Nonlinear/Freq Resp " - button that might help you.

Otherwise you might have to edit the bulk data directly if that is possible.

Good Luck

Thomas

Thanks Thomas,

but I need a nonlinear relationship depending on the velocity and not on the frequency.

At the moment I think it is only possible to edit the bulk data as you guessed


best regards,
Daniel
