chtMultiRegionFoam, conduction with a contact resistance between two solids
 
Hello,
I have a simple test case with 3 solid, and I am trying to solve a simple heat conduction inside those three solids. The third solid should not have any influence for now (see figure)

If I use
Code:

type            compressible::turbulentTemperatureCoupledBaffleMixed;
        value          uniform 300;
        neighbourFieldName T;
        K              solidThermo;
        KName          none;

as in the tutorial, it's working, I have a gradient of DT=q*Rth.

My problem is to introduce an additional resistance, for example a contact resistance between two solids.
I was planning on using the boundary condition fixedGradient, but I have an error when I tried to use such a boundary condition between two solids.


Code:

Attempt to cast type fixedGradient to type compressible::turbulentTemperatureCoupledBaffleMixed
Any idea how I can solve my problem ?

Thanks in advance for your help,

Hi,
I am a newbie in OF and I am also facing a problem similar to the one Romain posted.
My question: is it possible to set a contact resistance between two solids? (I am using the chtMultiRegionSimpleFoam solver).
Thank you in advance for your answer.

Ciao.
