Hello people,
I am working on multiphase analyses in fluent,i still now not able to find the continuity equation satisfied , i.e. mass flow rate difference not coming to zero in my analyses it comes values around for ex: + or - of 12345 atleast, i dont know why and the solution is not converging at all after some 10000 iterations in transient analyses at the time step of 10 per iterations and time step size of 0.001714.
I meshed this domain in GAMBIT of around 28000 structure quad mesh elements by blocking.And i used fluent for solving this problem, in multiphase i used two phases one is for water and other is for water vapour....in this analyses i try to solve for cavitation developed over the body in order to reduce the drag on the body, at last i can see the cavitation (vapour phase formed elliptical around the body in contour)but the continuity equation that is the difference of mass fluxes is not coming to zero,there is always a difference of around 5 digit value as i mentioned above.
and the incoming and outgoing mass flow rate value is around value of exp 9 terms ..i think its too high ..

for a cfd simulation without satisfying the continuity equation the analyses is wrong ..and in this analyses solution convergence is also not occuring after 10000 iteration in transient case..i dont know why whats the problem in my analyses ,always mass is adding up in between inlet and outlet can any one plz help me with this analyses..and i try to solve this analyses in steady state pressure or temperature coupled or divergence occure..plz some body help me...


Thank u,
