Detailed Description

This boundary condition provides a 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]

Usage

Property	Description	Required	Default value
rho	uniform density [kg/m3]	yes
pRefValue	reference pressure [Pa]	yes
pRefPoint	reference pressure location	yes

Example of the boundary condition specification:

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