Unable to perform last step even with completed convergence

Please login with a confirmed email address before reporting spam

Hi all!

When doing a computation, on a model which I introduced earlier in this post, I now have a working model for the Fluid Flow step. The second step would be the Heat Flow. The program is able to perform the computation with complete convergence, showing 100% for 'solution 1', however it fails to end the computation and continues iterating on GMRES untill I cancel the computation.

I have included snapshots of the 'progress' and the 'log', also showing the convergence for the segregated solver and GMRES.

Can anyone pinpoint why the program is unable to end the computation? I reckon the reason is in the phrase: Convergence criteria of the segregated solver are met but not all conditions for group Heat transfer T2 are fulfilled. but I do not know what is meant and how to act upon it.

All help is welcome, thank you!
