Class
    Foam::lumpedMassWallTemperatureFvPatchScalarField
 
Group
    grpThermoBoundaryConditions grpWallBoundaryConditions
 
Description
    Employs a lumped mass model for temperature.
 
    It considers a single temperature value for the whole patch and evaluates
    the temperature evolution using the net heat flux into the patch.
 
Usage
    \table
        Property     | Description                 | Required | Default value
        kappaMethod  | thermal conductivity option | yes      |
        Cp           | Heat capacity [J/kg.K]      | yes      |
        mass         | Total mass [kg]             | yes      |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    myPatch
    {
        type            lumpedMassWallTemperature;
        kappaMethod     fluidThermo;
        kappa           none;
        mass            1000;
        Cp              4100;
        value           uniform 300.0;
    }
