Hi,
I want to add damping to my model to do a modal analysis. After reading the help files several times and lots of unsuccesful attempt, I need more to the point information.
1. The damping solver doesn't support the constant damping when added to the material model. I want to simulate inherent damping, so where can I add this?
2. The results I get show no diffrence in damped and undamped frequencies, whatever value I use for constant damping (QR damped solver).
3. I read somewhere in the Ansys files that there are unly a few elements who support damping matrices (like combin, fluid,...). These elements are not useful to do a modal analysis though.
Can anybody help me out here,
I'm a bit lost,
Jeroen
PS: I suppose 0.1 is a normal value for a constant damping no?
