Fluent strange behaviour (occasional divergence)
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?:confused:
Thanks for your attention,
