  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).
  https://ansyshelp.ansys.com/public/account/secured?returnurl=/Views/Secured/corp/v242/en/wb_sim/ds_damping_controls.html?q=numerical%20damping
  
  We also have free courses describing how to use damping in ANsys.
  https://innovationspace.ansys.com/product/damping-effects/
  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
