Boundary Condition -- CFD Online Discussion Forums

September 27, 2017, 15:38	Boundary Condition	#1
cwl6750084 Member CWL Join Date: Nov 2015 Posts: 58 Rep Power: 10	I am simulating (turbulent) air flow across a long slab (as shown in the figure). Due to the size of the problem, I am thinking of simulating only a thin layer in the centre of slab as shown. However, I am not sure what boundary condition should I put on the two sides of the control volume (the green surfaces). I tried using the outflow condition but Fluent returned the error that outflow BC cannot be use together with a pressure outlet BC. Does anyone has any idea? Thanks in advance.
