Reply To: material damping and modal analysis

[paolo.neri]

Dear all

I'm  facing issue with beta coefficient. When I apply it as a global option in analysis settings, it works as I expect. But if I assign it to a specific material, it is ignored in the analysis, i.e. I always get the same (undamped) result regardless the beta value that I set in the material property. On the other hand, if I assign to the specific material the constant damping ratio, it works just fine. I'm performing harmonic response analysis with MSUP solver, to speed up the computation. Any suggestion?
