Steady state conjugate heat transfer analysis in openfoam version 5
 

Hi, I am running "chtMultiRegionSimpleFoam" solver and irrespective of the case, meshing and number of iterations, I get the note:

"Regions not converged after XXXXX iterations". I even tried decreasing the tolerance to 0.1, still the note comes:(

Can anyone tell me what could have been done better?
I am performing simulation for steadystate, laminar and incompressible flow.

How to give enough info to get help

If you upload your case I can cross-check your settings. fvScheme and fvSolution are not enough to judge about it.

Your case does not include ' thermophysicalProperties ' in constant/fluid or sink.
So it can not be run.

BTW, what kind/version of openfoam do you use?

Openfoam version 5
 

I use Openfoam version 5. Kindly find the updated case at

Dear Sirkarg,
As I use openfom > 6 and this solver is deprecated hereafter, I can not reproduce your example until I have enough time to install version 5. Sorry for late.

Best,
Ali

Can you share your solution output log (terminal)?

Best,
Ali
