A question about the dynamic mesh UDF
 
Hi, I want to simulate the flow in a cavity with a oscillating membrane at its bottom. Dynamics mesh should be used for this case. Now I know the shape and velocity of the membrane. How to write the UDF? Is it enough if I write the UDF only use the Macro DEFINE_GEOM without using DEFINE_GRID_MOTION? Any suggestions will be greatly appreciated.

hi Tango,

you are right. The interior grid nodes will be positioned automatically by solver.

good luck.
