Dynamic meshing - UDF
 

Hey,

I have started to work with dynamic meshing on a pressure valve for a moving valve disc. i have been using the UDF coding of a SDoF piston from ANSYS with some modifications. However it does not seem to be working
i have tried looking for turotials for UDF and dynamic meshing but many of the links have became invalid or not related.
If any one can guide me in the right directions for dynamic meshing or notice i might be doing something wrong

Thanks in Advance

To clarify to my problem. I'm doing FSI, and im using the system coupling option in Fluent, by doing this, it does not allow me to add a motion to the valve disc. I'm new to dynamic meshing and FSI, can someone kick start me with a few hints?:)
