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.

thanks

AlexanderZ will become famous soon enoughAlexanderZ will become famous soon enough
you may try to solve flow equation only, than add energy and continue simulation

best regards
