Class
    Foam::fv::fixedTemperatureConstraint
 
Description
    Fixed temperature equation constraint
 
Usage
    \verbatim
    fixedTemperature
    {
        type            fixedTemperatureConstraint;
 
        select          all;
 
        phase           gas; // Optional phase name
 
        // Uniform temperature constraint
        mode            uniform;
        temperature     constant 500; // Uniform temperature
 
        // // Looked-up field temperature constraint
        // T            T; // Temperature field name
    }
    \endverbatim
 
    Note:
        The 'uniform' option allows the use of a time-varying uniform
        temperature by means of the Function1 type.
