UDF-motion type
 

Hi everyone.

I'm studying the motion of a pressure valve. I need to write a UDF for the motion of the valve-disc.

currently i do not know which type of motion is best to use, e.g. CG_MOTION, GRID_MOTION etc?

The problem is a 2D problem and the valve disc only need to move in 1 direction.

Im new to using UDF and moving mesh.

Also could someone recommend a turotial for me to learn more on UDF and moving mesh?

Thanks in Advance
