Default Transient rotation
Posts: n/a
I want to solve a transient problem with time varying rotation. The approach can be either MRF or stationary reference. In both cases i have to specify rotations to the wall in absolute reference frame. Fluent doesnt have an option of including time varying profile or inclusion of Define profile UDF for rotation of walls.

If anybody has solved a similar problem, it wud be of great help if you could share the UDF and the approach.

Thanks for your time.

Regards Krishna
