heat source in solid

Hello there,
I'm trying to simulate the heat transfer in a piece of metal, which is heated by an electric current.
I already got a little bit familiar with laplacianFoam, is there some way to model a heat source inside of it?
Or do I have to use a different solver?
Thanks a lot!

heat source in laplacianFoam

you can model heat source! just by add a source term to the laplacianFoam equation
in creatFields.H

Code:

    volScalarField q

    (

        IOobject

        (

            "q",

            runTime.timeName(),

            mesh,

            IOobject::MUST_READ,

            IOobject::NO_WRITE

        ),

        mesh

    );

in laplacianFoam.C

Code:

fvm::ddt(T) - fvm::laplacian(DT, T) - q

then you should compile your solver with "wmake"! (look user guide)

then in your case study in folder zero you should add a file name "q"
you can apply different value from uniform or non-uniform heat source
for making the initial non uniform heat source use "setFields" or "funkySetFields"
for install "funkySetField", look at here:

Thanks a lot!
This approach saves me a lot of time! :)
