How to simulate pitching oscillation?

zkdkeen · December 11, 2013, 07:31

Hello everyone,
I am working on a pitching oscillation problem recently. Since I have the experience of simulating a fan rotating problem using CFX. In that case, one need to establish a general project, using 2 domains, one is stationary, the other is rotating, and interfaces between them. I think it would be easy to change the movement of rotation to the form of a=a0+am*sin(wt). The question is, where to find the oscillation options in this case? or is udf needed as well just like Fluent does?

Any suggestion will be appreciate!
Best regards!

You can do this entirely in CEL I suspect. Hopefully there should be no need for fortran.

Also consider the rigid body solver for this.
