I need to implement a boundary condition similar to directionMixed for unidirectional heat flux - anisotropic conduction - in a baffle inside a solid. In one predefined direction and if the temperature gradient between the baffle faces is positive, the baffle should work as an insulator (factor * dT/dx=0; 0 < factor < 1). If the temperature gradient is negative (heat flux in the reversed direction), it should work as the original material, as shown below. Please send me a quotation for this task.
Getting back to you @masb with just an idea that I came up with.
@rszoeke, would it be possible to define directional dependencies by functions inside the simulation or does Code_Aster has other possibilities to achieve that?
as far as I know, we can solve the heat conduction using laplacianFoam. We can then use inletOutlet BC to emulate the unidirectional heat flow in a baffle. I guess, Simscale, however, does not provide this possibility.
