outlet pressure boundary condition

Hey foamers,
I am using interFoam for my solver. now i have two outlets and two inlets..I am defining velocities at the inlets and setiing zeroGradient at the outlets....now my doubt is what pressure boundary condition should i set at the outlets?

Hi,
It all depends on your problem, can you describe in some more detail what the known quantities are or what you are trying to achieve.
To start with please see the tables on the code guide for common BC configurations and their typical stability https://www.openfoam.com/documentati...binations.html
