chek is on a distinguished road
Hi guys,

I'm trying to simulate downwards drop of an object at unit acceleration from air into the water. The tricky part is that the acceleration remains the same 1m/s2 even after interacting with the interface. I have no problems hooking the UDF to fluent.(DEFINE_CG_MOTION and DEFINE_SDOFPROPERTIES). However when i tried to preview mesh motion it doesn't move. Is there something wrong with my udf or is that something i have overlooked? Any advice would be greatly appreciated.
