Modelling Viscous Damping in Modal Frequency Response Analysis


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
