Default Fluent strange behaviour (occasional divergence)

muketa is on a distinguished road
Did you ever see Fluent suddenly diverging at n-th iteration (or in less than 5 or 6 iterations) saying "divergence detected in AMG solver" and than restarting the case with the same settings and initial condition, calculation go over n-th iteration without diverging?

I experienced this behaviour repetadly running a particular case (that incidentally with different value in pressure inlet boundary conditions dosen't show this behaviour).

What do you suggest?

Thanks for your attention,

Ciao from Italy,
