Hi, I am trying to simulate a two phase flow boiling of r134-a in 2d rectangular mesh. My calculation settings for transient are below. I keep seeing that the continuity residuals are not reaching the set convergence criteria of 1e-03. A mass imbalance as below is given: Â Â Â Â Â Â Â Â Â Â Â Â
         Mass Flow Rate        [kg/s]
-------------------------------- --------------------
              inlet        0.17317
             outlet      -0.24588628
        ---------------- --------------------
               Net     -0.072716281Â
Is the solution still correct and can I go ahead with running the calculation. How to know if the convergence is correct?Â

You need to have a very careful look at the flow, flux balance and mesh. You may need to refine the mesh where you're seeing the steep phase gradients and reduce the time step.Â
