Reply To: Correct CFX Pre Setup to avoid isolated fluid regions

Hi Mark,

To clarify, are the internal faces in this case the ones with a different code (.333) than the rest of the faces? Originally it was set as a wall however I didn't think this made sense to have the outer face set as an inlet/opening and the inner face set as a wall as I assumed that would cause an error? What I have currently set is the face highlighted in the above photo as the inlet and the opposite face (where the blue arrow is) as the outlet and all other faces as a non-slip wall. I am a bit unsure on what I should be setting these boundary conditions to instead.
