Damping ratio in SV or in DMPR for modal-spectral analysis | Ansys APDL

      i have a script APDL which create the spectrum in one direction, but the damping ratio is applied in DMPRAT,0.04 and also in SV,0.04,.... (first value).

      But i wanted to made the same thing in workbench, with a modale and spectrale modulus, but in the script, i saw that the damping ratio is not applied in the SV, only the DMPRAT command.

      i would like to know which one is better ? if i need to explicit the value twice, or only with DMPRAT or SV ? and what is the point to use one and not the other ? Which way is the right way ?

      For the context, i made my analyse modal-spectral with a script APDL, and i would like to stoping use my script and use workbench, but i didn't got the same results, the only way is to delete the damping ratio in the SV command.

      Hi,

      It seems that you have already posted same question here: Impact of the damping ratio in SV and DMPR command (ansys.com)

      I will close this thread and keep the other one open.

      Thanks,
