Forgive me, I am not sure what to ask. I am trying to use the matchedFlowRateOutletVelocity boundary condition for compressible flow, and I am not sure what sorts of things are allowable for boundary conditions with this condition. I came up with some questions:

When matchedFlowRateOutletVelocity is applied as a boundary condition for U, what should the boundary conditions be for p, T, nut, k, epsilon, and alpat when running with rhoSimpleFoam?

More simply when matchedFlowRateOutletVelocity is applied as a boundary condition for U, what
should p and T be when running rhoPimpleFoam?


I usually get an error like this. Maybe I cannot use the calculated b.c. Perhaps, fixedValue?

You are probably trying to solve for a field with a default boundary condition.
