Detailed Description

This is a pressure boundary condition, whose value is calculated as the hydrostatic pressure based on a given displacement:

\[ p = -\rho*g*\zeta \]

$ \rho $ = density [kg/m3]
$ g $ = acceleration due to gravity [m/s2]
$ \zeta $ = wave amplitude [m]

The wave amplitude is updated as part of the calculation, derived from the local volumetric flux.


Patch usage

Property Description Required Default value
phi flux field name no phi
rho density field name no rho
zeta wave amplitude field name no zeta

Example of the boundary condition specification:

    myPatch
    {
        type            waveSurfacePressure;
        phi             phi;
        rho             rho;
        zeta            zeta;
        value           uniform 0;  // place holder
    }

The density field is only required if the flux is mass-based as opposed to volumetric-based.
