Hello all,

I am new to Openfoam.

I am trying to set a heat source in a solid domain.
In my case, the mesh is exported from Salome, and a certain solid region is named "source" for the heat source in Salome. By "ideasUnvToFoam", the mesh is converted now. Looking at the polyMesh/cellZones, I can see

1
(
source
{
type cellZone;
cellLabels List<label>

)
;
}
)

// ************************************************** *********************** //

So now I want to use this "source" as a heat sourc. I am using "scalarTransportFoam" for the simulaiton.

At the moment, I use this fvOption file

FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "constant";
object fvOptions;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

heatSource
{
type scalarSemiImplicitSource;
active true;
selectionMode cellZone;

scalarSemiImplicitSourceCoeffs
{
// selectionMode cellZone; // all, cellSet, cellZone, points
cellSet source;
volumeMode absolute; // absolute, specific
injectionRateSuSp
{
T (1 0);
}
}
}

but the terminal said

What is wrong now? Because I am not familiar with Openfoam enough, could someone help me?

Best regards,

Hello,

I solved the problem above, but I face a new problem.
Would someone help me?
