Class
    Foam::fv::semiImplicitSource
 
Description
    Semi-implicit source, described using an input dictionary.  The injection
    rate coefficients are specified as pairs of Su-Sp coefficients, i.e.
 
        \f[
            S(x) = S_u + S_p x
        \f]
 
    where
    \vartable
        S(x)    | net source for field 'x'
        S_u     | explicit source contribution
        S_p     | linearised implicit contribution
    \endvartable
 
    Example tabulated heat source specification for internal energy:
    \verbatim
    volumeMode      absolute; // specific
    sources
    {
        e
        {
            explicit table ((0 0) (1.5 $power));
            implicit 0;
        }
    }
    \endverbatim
 
    Example coded heat source specification for enthalpy:
    \verbatim
    volumeMode      absolute; // specific
    sources
    {
        h
        {
            explicit
            {
                type coded;
                name heatInjection;
                code
                #{
                    // Power amplitude
                    const scalar powerAmplitude = 1000;
 
                    // x is the current time
                    return mag(powerAmplitude*sin(x));
                #};
            }
            implicit 0;
        }
    }
    \endverbatim
 
    Valid fvModels for the \c volumeMode entry include:
    - absolute: values are given as <quantity>
    - specific: values are given as <quantity>/m3
