hello foamer

I am simulating 2d hydraulic jump using interFoam.

inlet velocity is subcritical condition and I know only velocity and water depth at inlet.

this subcritical flow will be changed to supercritical flow when flow pass semi circular shaped weir.

To make hydraulic jump, I want to specify Hydrostatic pressure distribution at outlet boundary condition.

but in case of interfoam, we should set up "p_rgh "not "p".

as far as i know, p_rgh is p - rgh but i don't understand what it mean exactly.

anyway I want to input Hydrostatic pressure into boundary condition of p_rgh at outlet.

how can I do it??

please help me.
