Mass flow inlet compressible flow
 
Dear Fluent users

I am currently running a Large eddy simulation, with a mass flow inlet. I specify the mass flow rate. How do I specify the pressure. Is the inlet to be standard atmospheric pressure ? Do I need to initialise the flow to standard air pressure

thanks

Richard

the pressure will be guided by the other boundary conditions

with prescribed mass flow at inlet and outlet, only one solution is possible,that is, the other variable adjust themself iteratively;
