Detailed Description

This boundary condition provides static pressure condition for p_rgh, calculated as:

\‍[ p_rgh = p - \rho g (h - hRef) \‍]

where

$ p_rgh $=Pseudo hydrostatic pressure [Pa]
$ p $=Static pressure [Pa]
$ h $=Height in the opposite direction to gravity
$ hRef $=Reference height in the opposite direction to gravity
$ \rho $=density
$ g $=acceleration due to gravity [m/s^2]
Usage
Property Description Required Default value
rho rho field name no rho
p static pressure yes

Example of the boundary condition specification: 

    <patchName>
    {
        type            prghPressure;
        rho             rho;
        p               uniform 0;
        value           uniform 0; // optional initial value
    }
