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
    }
