August 2, 2012, 01:08	Incorrect wall velocity vectors	#1
jc239485 New Member Chuck Walter Join Date: Aug 2012 Posts: 2 Rep Power: 0	Hey, I am simulating a 2D purging case of water on water. I have a rectangular profile of water with an inlet and an outlet flowing over another rectangular profile of water. After a few seconds of the simulation, velocity vectors acting upward against the roof (wall) are developed and stay there for the remainder of the simulation. Does anyone know how to solve this problem.
