A problem in simulating heat transfer between two solid layers

[hexuanze]

Dear Gpyro users,

I have encountered an issue when I try to simulate the heat transfer between two layer solid phases. I built a 1D domain, which contains two solids. In between, Gpyro can use hcr (inverse contact resistance) to calculate heat transfer. The boundary condition is one adiabatic surface and one fixed temperature surface. 

However, no matter what values I used for hcr, from 0 to infinite, the results never changed. I feel like this hcr doesn't involve in the calculation. 

If some of you know how to use the "hcr" properly or you encountered the similar issue before, could you please kindly help check the attached file and help solve this problem.

Thank you very much.

Best,
