Class
    Foam::uniformTotalPressureFvPatchScalarField
 
Description
    This boundary condition provides a time-varying form of the uniform total
    pressure boundary condition Foam::totalPressureFvPatchField.
 
Usage
    \table
        Property     | Description                | Required    | Default value
        U            | Velocity field name        | no          | U
        phi          | Flux field name            | no          | phi
        rho          | Density field name         | no          | rho
        psi          | Compressibility field name | no          | none
        gamma        | (Cp/Cv)                    | no          | 1
        p0           | Total pressure as a function of time | yes |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            uniformTotalPressure;
        p0              1e5;
    }
    \endverbatim
 
    The \c p0 entry is specified as a Function1 type, able to describe
    time varying functions.
