Hi Foamers

I am simulationg a fluid-structure interaction problem and i need to transfer the heat flux from the fluid patch to the solid patch.
I wrote a .H file where :
void HeatFluxFvPatchScalarField::updateCoeffs()
if (updated())

const dictionary& transportProperties =
db().lookupObject<IOdictionary>("transportProperti es");

dimensionedScalar k(transportProperties.lookup("k"));

vectorField n = patch().nf();

// Info<< "\n Traction displacement \n" << endl;
gradient() =(HeatFlux_)/(k.value())*(-1);


and i want to ask if there is anything wrong in what i wrote?

Instead of starting from scratch I would take a look at the implementations in the chtMultiRegionFoam tutorial. They use this BC to map temperature between coupled solid and liquid patches:
