CFD Online Discussion Forums - Cyclic condition for temperature gradient

Hi to all

I'm working with the conjugateHeatFoam solver, in the 1.5-dev version. For the solid region, I need the cyclic condition for to faces but for link the temperature gradient, not for the temperature. I have tried to create a new variable GT which is the temperature gradient, and replacing the equation term

Code:

fvm::laplacian(DTsolid, Tsolid)

for

Code:

fvm::div(DTsolid, GT)

in the solver, but I obtain an error when I compile it.
Does anyone knows any form to do that?

Thanks in advance
