Hello,
I have two questions that needs clarifications.

1. Does species transport support periodic Boundary condition? Because I would like to simulate a species transport problem and observe the flow due to gravity in a vertical pipe. If periodic BC works, then I don't have to create a longer pipe (Viscous Model - Laminar)


2. I was simulating a species transport problem in a horizontal pipe and was analyzing the flow due to gravity. I want to apply wall BC to the inlet, outlet and pipe wall because I want to have a static pipe with zero velocity. So after standard initialization from the input, i tried to patch a constant pressure value across the domain. But when i looked at the pressure contour it shows zero. I tried changing different pressure values but still the same. Can anyone help me on how I can patch a pressure across the domain with the above said boundary conditions? (Viscous Model - Laminar)
