single phase boiling
 
H dears
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!
