Modeling Bleed in Supersonic Flow

Mohd Yousuf Ali

I require help to model bleed flow inside a duct in a supersonic flow. It occurs that FLUENT does not recognize the mass flow inlet, pressure inlet, velocity inlet boundary condition inside the duct once a pressure inlet boundary is initiated at the start of the solution i.e. the solution starts from the taking the pressure inlet boundary condition.

Kinldy advice me how to put two similar boundary conditions one for the start of the solution (input boundary) and the other inside the solution domain.
