How do I model thermal contact resistance using the Matlab partial differential toolbox?

I am using the matlab partial differential toolbox to model heat flow between two materials. I need to be able to account for the thermal contact resistance between these two materials. The thermal properties feature only accounts for thermal conductivity. How would I go about implementing it?

many thanks,

Daniel

Can you put a thin layer between the two materials and use an effective conductivity? Something like: keff = deltax/R where R is resistance and deltax is the thickness of the layer (I've assumed 'resistance' here is the inverse of a heat transfer coefficient - you'll need to make sure the units are correct).
