boundary condition and differenet constant properties for for two different region.

Hello friends,

I am new user with openfoam. the problem geometry is the small cube inside the big cube. The small cube inside the bigger cube is surrounded by air. I want to analize the current distribution in the full domain also in small cube. So, I can't consider the small cube as wall because I have to analyze the small cube surface current distribution.

the problem is: the thermal conductivity is different for air and small cube. but, only one equation is used to solve the problem and that equation contain the thermal conductivity term. so, How I have to define the constant properties (thermal consuctivity) for two different region? and How I have to define the boundary condition at the small cube surface which is contact with air?

Kind regards

hi,
take a look at chtMultiRegionFoam.
