Hi,

 

I'm beginner of RADIOSS.

 

I want to set the structural damping of steel.

 

But I don't know how.

 

I think there is no setting for structural damping in /DAMP ,

 

What should I do?

 

Like OptiStruct(PARAM, G) , is there any card?

 

Thanks

    /DAMP is related to  Rayleigh damping.

    In order to use it you need to have the alpha and beta .

     

    if you just need to damp the vibration to have the equilibrium state, you can use a second engine run with /ADYREL.

     

    Regards
