FEMAP + NASTRAN - DAMPER CBUSH1D
FEMAP + NASTRAN - DAMPER CBUSH1D
(OP)
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

RE: FEMAP + NASTRAN - DAMPER CBUSH1D
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

RE: FEMAP + NASTRAN - DAMPER CBUSH1D
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
