hcmosley1 is on a distinguished road
My problem is modelling a large furnace in steady state to get a temperature distribution.

I keep getting temperature limited in roughly 96 cells but this fluctuates each iteration from 96 cells to 2 cells? I believe I have a good mesh roughly 1.6m cells. and I have extended the outlet to reduce reversed flow but it is still happening.

Also is there any reason for my k residual not converging. I have a attached a picture of them.

you may try to solve flow equation only, than add energy and continue simulation

best regards
