I wanted to start a threat to discuss about the present state of conjugate heat transfer solvers in OpenFOAM.

Recently I have been trying to carry out a research project based on cht and in reviewing literature I have found this:http://www.tfd.chalmers.se/~hani/kur...eport_Turo.pdf
Here, the author clearly states that cht solvers in OpenFOAM are considerably worse than other commercial options in terms of convergence speed.

Furthermore, in the OpenFOAM.org funding article (https://openfoam.org/news/funding-2017/) they explicitly mention that "Heat transfer, including conjugate heat transfer (CHT)" require "significant code refactoring and/or rewriting" and will be addressed in upcoming versions.

With this said, do you believe that state of cht codes are good enough to invest time and effort into serious research in conjugate heat transfer using OpenFOAM?

Thank you for your opinions.

If you have the opportunity invest serious time and effort to conjugate heat transfer research, you should talk to the OpenFOAM Foundation to see if your work could be part of the "significant code refactoring and/or rewriting" needed to address the issues that affect your work. Things won't advance unless someone puts in the work.
