Class
    Foam::pressureFvPatchScalarField
 
Description
    Static pressure boundary condition
 
    Used as the base-class for static pressure boundary conditions force
    alternative pressure variables, e.g. p_rgh.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        p            | static pressure         | yes         |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            pressure;
        p               uniform 0;
        value           uniform 0; // optional initial value
    }
    \endverbatim
