I am working on a case in which a jet is injected from a nozzle into atmosphere. I am using interFoam solver. What should I specify at the outlet for pressure boundary condition?


The pressure at outlet is 101325 Pa (1 atm). I am confused by p_rgh in interFoam. What should be the boundary condition in p_rgh file so that my outlet is at atmospheric conditions?

I like to avoid that confusion alltogether and use prghTotalPressure for static pressure:
