Hi all,
I am modelling the combustion in a small turbojet engine (just the combustion chamber). I have built the solid model to be just the fluid domain (how do I add a screenshot?). Its a non-premixed combustion, k-epsilon viscous model and P1 radiation. I haven't altered anything else in the solution controls before initialisation and solving. The error I'm countering is this (after only <5 iterations): # Divergence detected in AMG solver: pressure correction -> Turning off correction scaling! # Divergence detected in AMG solver: pressure correction -> Increasing relaxation sweeps! Error: Divergence detected in AMG solver: pressure correction Error Object: #f I suspect the problem is in the way I've set up the solver so I was hoping someone with more experience can tell me some potential causes. |
