define wall in fluent when hooking grid motion
 
Hi everybody,

I'm trying to work with dynamic meshes with a DEFINE_GRID_MOTION UDF. The UDF does work very well and it moved boundary,( this boundary defined Wall). after 1 time step , "No Slip" Condition does`nt work on boundary and velocity on this boundary is non zero.


i think, i must add one part in my udf to redefine boundary. if this is true, please help me to add this part.:confused::confused::confused:

Thanks
