Rioual is still having a problem:
Hello Robert,

Thanks for your input.
Do you have references concerning the Kern method and Hertz method ?

Thanks,

Fr.

Robert Caulk proposed the following answer:
Hello,

That is the thermal resistance using a cross sectional area based on the
contact area between two spherical particles using the Kern method.

If you prefer, you can use the hertz method with

thermal.useKernMethod = False
thermal.useHertzMethod = True

Or set them both false to consider a wall consuming the space between
the particle centers (better for continuum modeling).

You can easily add in which ever relationship you want there, such as
the method you refer to in CFD.

Cheers,

robert
