I'm currently using Fluent, and am wondering if there is a way to prescribe a constant velocity in one direction, but have motion in another direction be dictated by the hydrodynamic forces?
Specifically, I want to track how an object translates in the y direction as a result of arms rotating about the z-axis. I have been able to create the flapping motion using a UDF with the CG_MOTION macro, but am unsure how to combine or integrate this into the 6 DOF solver.
Can I simply assign 2 UDFs to the dynamic mesh zones, or is there a way to write a SDOF_PROPERTIES function that takes into account constant rotational velocity?
Thank you for the help!
