Hi, is there anyone has tried use ansys to simulate a bearing? I met converge problem and hope somebody can help me. Thanks.

I found it is really hard to set the contact between ball and cage,inner race,outer race. I set the contact between ball and cage is frictionless.The interface treatment is "add offset and ramp effect". The contact between ball and ring is frictional with a small frictional coefficient. Treatment is "adjust to touch".These nonlinear contact can bring a lot problems. I do a modal analysis and cage flies out. Do you have ideas to solve it? Thanks.

Also, RTFM, as they say. There are sections on rotordynamics in the Mechanical Applications manual and the Mechanical APDL Manual, and a Workbench verification problem at VMMECH087.
