Hi all,
The situation that I want to simulate is this: There is a cylinder, and gravity is applied. Then I give boundary load on the floor of the cylinder. I want to change the frequency of boundary load, then get the frequency response. Without gravity, it is very easy-I can just use frequency sweep, but if I add gravity the frequency sweep is also applied to gravity. So I want to sweep the frequency only for the boudnary load not for gravity.
Any comment will be helpful. Thank you.
