Look at the MDAMP command in the help manual.


 


We can define a command snippet using the above command defining the damping ratio for each mode.


 


Thus depending on the mode and its frequency you will add the damping ratio you have/showing in your graph/table.


 


A sample command is (adding damping ratio to 6 modes):


mdamp,1,.01,.04,.03,.04,.05,.06 ! specify modal damping for modes 1 to 6


 


Best of luck
