Hi,

I'm running a multiphase flow (mixture model), with 3 secondary phases with diameters of 1, 100, and 750 micron. I get a great convergence on 1 micron and 100 micron particles, but the convergence of 750 micron phase is not acceptable! (residuals go up to 4e-2!).

I can't understand why this happens, and I'd like to know that how I can solve this issue.

Thanks

Change time step size.
