Boundary Condition

AliMobasher · April 19, 2022, 06:28

Hi Everyone,
I am performing a steady-state simulation of a single-stage turbine using CFX and I need to set the flow direction at Inlet Boundary same as the flow direction at Outlet Boundary (a dynamic boundary condition).
Does anyone know how can I do this?

On inlet and outlet, you can try an interface with a translational periodic condition. Use a massflow or pressure drop as target to get a pressure drop or massflow as result.

Not sure if it works, but you can give it a try.
