Default directionMixed for unidirectional heat flux - conduction.

masb is on a distinguished road

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,
