      Hello,

      In other softwares I am able to define Structural Damping for a Steel Material which I usually use 0.05 and a Critical Damping of 2-5%.

      I understand that Damping Ratio is Critical Damping (I have put 5%, so 0.05).

      Numerical Damping value of 0.005 is the Structural Damping?

      Someone could confirm this?

      Thank you in advance.

      Hi

      As it says it is numerical damping:

      Seacrh for numerical damping in the help manual (Mechanical section in help).

      We also have free courses describing how to use damping in ANsys.

      https://innovationspace.ansys.com/courses/courses/intro-to-modal-based-methods/lessons/

       

      Also the help manual has a lot of info on that.

      All the best

      Erik
