Hi Everyone
I am performing a CFD simulation on cavitation for control valve application.
Fluid medium is water and it is a steady state simulation.Multiphase VOF cavitation model enabled.

Actual given Conditions are Inlet100psi as total pressure and outlet 17psi static pressure.

During simulation at 45psi pressure at outlet,I have observed the incipient cavitation (Starting point of cavitation).Untill that my convergence was very good.

Now i am further reducing the outlet static pressure to 40psi to see the next stage of cavitation, my sollution is diverging (see below the error message)

" Error: AMG solver diverged! Please double check settings and restart.
A floating point exception has occurred: floating point exception [Divide by zero]. The specific cause cannot be identified. Please refer to the troubleshooting section of the User's Guide.
Command: RunSimulation
CompletedCommand: RunSimulation
In: [Machine::main, SimulationIterator::startSimulation, SteadySolver::step]

kindly guide me why i am getting this error and give me th esollution to overcome this .
