Class
    Foam::fv::codedFvModel
 
Description
   Constructs on-the-fly fvModel source from user-supplied code
 
Usage
    Example usage in constant/fvModels:
    \verbatim
    energySource
    {
        type            coded;
 
        cellZone        all;
 
        field           h;
 
        codeInclude
        #{
        #};
 
        codeAddSup
        #{
            Pout<< "**codeAddSup**" << endl;
            const Time& time = mesh().time();
            const scalarField& V = mesh().V();
            scalarField& heSource = eqn.source();
            heSource -= 0.1*sqr(time.value())*V;
        #};
 
        codeAddRhoSup
        #{
            Pout<< "**codeAddRhoSup**" << endl;
        #};
 
        codeAddAlphaRhoSup
        #{
            Pout<< "**codeAddAlphaRhoSup**" << endl;
        #};
    }
    \endverbatim
