I am trying to simulate boiling in a bottom heated duct via AVL FIRE software . the default values for convergence criteria and under-relaxation factors leads to divergency . what convergence criteria and under-relaxation factors do you recommand to use?
Any help will be appreciated!

Hello Raza
first this is fluent modelling cfd online group and i am unaware of the AVL FIRE software that you are using but i like to tell you that in fluent you can silulate such a model.
There is a option in eulerian >boiling model
I hope that you can try it for your boiling purpose
