Dynamic Meshing UDF

jfeaster · July 31, 2013, 17:11

Hey all,
Hopefully only a quick question: I'm using the Dynamic Meshing option in FLUENT.
Is there another method to apply translational and angular velocities to a body other than the manipulation of the center of gravity? Ideally one that uses the frame of reference of the origin to manipulate a body.

If this has been addressed somewhere else in CFD-Online please link it. Your help is greatly appreciated!

I think this can be done with DEFINE_GRID_MOTION macro.
