Dynamic mesh for rotating wall - UDF ?
Hello everybody!

I really need help on that issue: I have to control (by a profile law) the rotation of the walls of my geometry during a transient simulation, using the "Dynamic mesh" tool. My researches make me understand that I have to use a smoothing mesh with a UDF hooked under "rigid body" option. But I'm not able to write a UDF alone without any example.

Would anybody have a sample of UDF close to what I need? Examples provided in Fluent tutorials are too far from my problem to really be useful. Any suggestion is welcome!

Thank you very much!
