 April 3, 2004, 12:02 rotation speed in the domain #1 jiaye gan Guest   Posts: n/a Hi Everyone: I am a new cfx user,I got some problem during using the soft to simulate hydraulic burbine. I know that it must be specified a rotation speed in the domain option. But I don't know what the rotation speed means. Whether is it an average speed of the domain? We know that different points in the domain have different rotation speed. How to explain it? All your returns would be appreciated. Thanks!
