zerogradient BC in fluent
 

Hi everyone,

I'm trying to apply the boundary conditions set in OpenFOAM to Fluent.
Is there a method for applying them? Please let me know.

inlet : mass flow rate = 5 kg/s P=zerogradient T=800 K
outlet : if velocity is subsonic, P=fixedvalue(1 bar) else, P=zerogradient. T=zerogradient, velocity=zerogradient


it's internal compressible flow,
pressure based, k-e Relizable
species transport - eddy-dissipation volumetric (ethylene air)
