UDF for oscilliating ball in a ball check valve

I am trying to simulate the motion of a ball in a check valve using a 2D model in Fluent.
From my research and several iterations I was able to define the DOF of the ball using the DEFINE_SDOF UDF, however that does not simulate my problem. But rather just gives the ball the freedom to translate or rotate independent of the inlet velocity. I tried to use DEFINE_CG_MOTION but i am not sure what to define for the velocity. I only want motion in the y-direction to be completely dependent on pressure or velocity. Any suggestions would be appreciated. ANd yes I did check the tutorial on this forum but it is for a specific problem. |
