Simulating from EVC to EVO in exhaust ducts
 
Hello, I'm simulating the discharge run of an ICE (star CD vers 3.26). My troubles are in relation to the boundary condition to impose at the end of the exhaust duct. I use a calculated condition from a 1D simulation code (like Wave or GT-Power) defined at the same section that i have in the 3D model (end of the exhaust's primary pipe). The question regards if it's better to impose a Flow Mass condition (Inlet), Total Pressure or Static Pressure.

Thanks to everyone form your help.
