Exclamation Simulation on fluent 14

NAD is on a distinguished road
I was running a few simulations on fluent 6.3.26. Recently, I wanted to switch to fluent 14. So first I ran a simulation on fluent 6.3.26, it worked very well. Then I ran the same simulation on fluent 14, but this time I got divergence from the first iteration and fluent displayed this message:

# Divergence detected in AMG solver: x-momentum -> Increasing relaxation sweeps!
Error: Divergence detected in AMG solver: x-momentum
Error Object: #f

What would be the problem here?

Best regards,
