How to define a damping ratio for the Modal Bodies (instead of the Stiffness Proportional Ratio)?

- ksi = 0.01 # damping ratio
- motionObjects = ExtAPI.DataModel.GetUserObjects("ANSYSMotion")
- for mybp in motionObjects:
- if mybp.Name == "BodyProperties":
- modes = mybp.AllProperties[13]
- frequency = modes.Value['Definition/Modes/Frequency']
- stiff_prop_ratio = modes.Value['Definition/Modes/StiffnessProportionalRatio']
- for i in range(6,len(stiff_prop_ratio)):
- stiff_prop_ratio[i] = 2*ksi /(frequency[i]*2*pi)
- modes.ValidState = ValidStateEnum.StateValid
- ExtAPI.DataModel.Tree.Refresh()
