Class
    Foam::inletOutletTotalTemperatureFvPatchScalarField

Group
    grpOutletBoundaryConditions

Description
    This boundary condition provides an outflow condition for total
    temperature for use with supersonic cases, where a user-specified
    value is applied in the case of reverse flow.

Usage
    \table
        Property     | Description             | Required    | Default value
        U            | velocity field name     | no          | U
        phi          | flux field name         | no          | phi
        psi          | compressibility field name |  no      | psi
        gamma        | heat capacity ration (Cp/Cv) | yes    |
        inletValue   | reverse flow (inlet) value | yes      |
        T0           | static temperature [K]  | yes         |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            inletOutletTotalTemperature;
        U               U;
        phi             phi;
        psi             psi;
        gamma           gamma;
        inletValue      uniform 0;
        T0              uniform 0;
        value           uniform 0;
    }
    \endverbatim
