Using RADIOSS Bulk Data on HyperMesh12

Altair Forum User

Hi,

I need to add a damping coefficient on my structural analysis. I must add the Rayleigh Damping model (where I define the alpha and beta coefficients).
I've searched on Internet and some people said to use the Radioss Bulk Data profile, but it is unavaliable on Hypermesh 12 because it is called Optistruct (I've read this in another forum). Then, I tried to use the Optistruct profile, but there is no 'Damping' or 'Damp Coefficient' on the control cards. What should I do? Is there any other profile on hypermesh where I can run a transient analysis with damping?
