Hi dear friend :

thank you for paying attention .

Would you please , example I studied in fluent 5.2.3 has such situatiobn I wanted , but some unrael condiotns was in it , for example gravity was set 5e-5 in it well it converged after some itterations but it would not give good answer when I increase gravity . would you check these parameter in it .
