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
    }
