Hi all I am fairly new to Ope
 
Hi all
I am fairly new to OpenFoam so if anyone could help me, I'd appreciate it. I am solving a simple diffusion equation of the form
fvm::laplacian(gamma,phi) == Src
How does one implement an effective gamma at a face separating two cells with different gamma values (i.e. different materials). This would be done for any solid heat conduction problem (where an interface between solid materials of different conductivities exists).
As I understand it, it is necessary to define an interpolation scheme and add a weighting parameter to the laplacian operator.
Could somebody please clarify how this is done practically in OpenFOAM, or at least point me to an example where this is done.

Thankyou in advance
