Default convergence criteria
Posts: n/a

i am modelling (Mixture model) two phase flow (air-water) in vertical pipe with velocity inlet for water and air and pressure outlet for mixture at the exit. i have some results but they donot show any convergence, specially continuity equation does not decrease below 10-3 while rest goes to 10-4. How should i ensure whether the results i obtained are converged. I still need to perform the experiments so i dont have actual results. I am thinking of using monitoring mass flow rate of the mixture at the oulet on the top or should i use target massflow rate.

Advice needed.
