Modelling Viscous Damping in Modal Frequency Response Analysis

Altair Forum User

Hi everybody,

I need to apply viscous damping properties (function of frequency) in a material card, to carry out a modal FRF. It's seems to be not possible. I don't find any help or suggestion on forum.

Please help me.

Thank you in advance.

Regards
