Hello everybody !

I am actually solving a problem of Conjugate Heat Transfer in a lid driven cavity with a solid block placed at the middle using C programming language. I have a seperate loop which solves the energy equation, which contains the convection and conduction governing equations.

The problem I'm facing is that my conduction loop isn't converging. I am using RMS residuals and it seems to be stuck at a particular value which suggests that the conduction matrix is taking alternating forms every other loop. Any suggestions to get the loop converged ?

Thanks a lot !
