Bismillah....

I simulate the refrigerant R134a in horizontal tube which is evaporated, indeed, the quality of fluid changes from .1 untill 1, definitely the prop. changes too. I take it mterial from a journal , and I've done some of material, but found stack related to running in fluent, n
my iteration not converged, whereas :
1) my grid good enaugh
2) I've reduced under relax. factor
3) second order upwind
4) adaption on wall

although converged , the result is not representative (i compared it with the experiment from the journal)
best regard,
Aminullah
