muketa New Member Join Date: Jul 2009 Posts: 7 Rep Power: 17	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, muketa
