Reply To: multiphase model

[SRP]

I suggest to try few things:

1) Refine the mesh where you there are sharp velocity gradients.

2) Try to adjust the relaxation factor.

3) If you are running a transient simulation, reduce the time step size and increase the number of iterations per time step.

4) You should also confirm that the turbulence model you are employing is appropriate for your particular issue.

Hope you find this useful.

Thank you
