May 2, 2018, 13:13	UDF for terminal velocity	#1
sikandar New Member Star Join Date: Apr 2018 Posts: 3 Rep Power: 8	I am dealing with a simple case of air water VOF modeling in 2D, where bubble moves with by buoyancy forces hence there is no inlet in bottom, the mesh is uniform, 60 by 600mm column and 3mm bubble is initialized at 10mm level. how can i find the gravity center of bubble for accurate terminal velocity. If i have to write UDF kindly share any example or guide for this issue. thanks
