I'm working on Conjugate Heat Transfer (CHT) problems and would like to discuss possible approaches. As far as I know, there are two main options:

1- Use the chtMultiRegion solvers available within OpenFOAM.
2- Couple OpenFOAM with external solvers (e.g., CalculiX) through a coupling library like preCICE.

For example, consider the case of simulating an industrial oven with numerous solid components and internal cavities where thermal radiation must also be taken into account.

How would you approach this kind of CHT problem and why? What has your experience been like using either the built-in chtMultiRegion capabilities or external solver coupling?

I'm open to all kinds of responses, but I'm particularly interested in hearing from those who have practical experience using both methods. If you have strong opinions or insights about one approach versus the other, please share your thoughts!

I would not use openfoam because it would be very painful for such cases. But i guess your question is about using openFOAM. In that case, multi-region foam makes most sense.
