Inlet and outlet boundaries - Concentric cylinders

Please login with a confirmed email address before reporting spam

Hello all,

I have two concentri cylinder with two gases flowing in each cylinder. I was able to specify the inlet boundary conditions for both of the cylinders but I wasn't able to specify outlet conditions for the inner cylinder (says not applicable). I looked at the solution after solving and didn't see any out flow from the inner cylinder. Thanks for reading! Any suggestions are appreciated!
