Question: heat conduction in multiphase solid
 

I want to simulate steady state heat conduction through a multiphase solid, e.g., two separated phases and each phase has a specific thermal conductivity.

Can fluent solve this problem?

I will know the detailed location for each phase. Then how can I specify the location-dependent thermal conductivity?

It seems to be a simple problem, but I am just a beginner and cannot figure out the approach. Your response will be greatly appreciated.
