Hi,

I'm trying to set up a directionMixed (OpenFOAM) internal boundary condition for unidirectional heat flux - anisotropic conduction - in a baffle inside a solid. In one direction the baffle should work as an insulator dT/dx=0. If the temperature gradient is reversed, the baffle (heat flux in the reversed direction), it should work as the original material, as shown below. Any help is welcomed.

Thanks in advance,

Marco.
