Detailed Description

This boundary condition provides a phase-based hydrostatic pressure condition, calculated as:

\[ p_{hyd} = p_{ref} + \rho g (x - x_{ref}) \]

where

\( p_{hyd} \)	=	hyrostatic pressure [Pa]
\( p_{ref} \)	=	reference pressure [Pa]
\( x_{ref} \)	=	reference point in Cartesian coordinates
\( \rho \)	=	density (assumed uniform)
\( g \)	=	acceleration due to gravity [m/s2]

The values are assigned according to the phase-fraction field:

1: apply \(p_{hyd}\)
0: apply a zero-gradient condition

Usage

Property	Description	Required	Default value
`phaseFraction`	phase-fraction field name	no	alpha
`rho`	density field name	no	rho
`pRefValue`	reference pressure [Pa]	yes
`pRefPoint`	reference pressure location	yes

Example of the boundary condition specification:

    <patchName>
    {
        type            phaseHydrostaticPressure;
        phaseFraction   alpha1;
        rho             rho;
        pRefValue       1e5;
        pRefPoint       (0 0 0);
        value           uniform 0; // optional initial value
    }
