UDF for Sloshing
I am working on a project about VOF (sloshing tank) that I want to use UDF for frame motion.for example ''Pitch move'' , ''Roll move'' or ''surge move''.I want to simulate surge move that it is only velocity in x axis depending on time.I want to help some one in its UDF.should i use with ''DEFINE_GRID_MOTION'' or DEFINE_ZONE_MOTION?
can any body please say about,how can i this UDF write?
