Class
    Foam::fv::heatSource

Description
    Model for applying a heat source. Requires either the power, Q, or the
    power per unit volume, q, to be specified.

Usage
    Example usage:
    \verbatim
    heatSource
    {
        type            heatSource;

        selectionMode   cellSet;
        cellSet         heater;

        Q               1e6;
    }
    \endverbatim
