Opening BC: Normal to boundary -- CFD Online Discussion Forums

September 19, 2007, 04:35	Opening BC: Normal to boundary	#1
Jan Ramboer Guest Posts: n/a	Hello all, In a calculation, i specify the opening boundary condition because I am having problems with backflow at the outlet. There is an option set "Normal to Boundary" for the velocity direction. Everything converges well, but when I plot the velocity vectors on my outlet surface I notice that they are not at all normal to the boundary. Is this a bug? (using CFX 10). Greetz, Jan
