Hi,
Guys I am trying to simulate the fulfilling of a bottle with compressed air in Fluent.
I set as boundary conditions Inlet_pressure - is a constant value, and mass flow inlet also a constant value.

Models: viscous-laminar, energy on

Now when I run the simulation I receive the following errors


iter continuity x-velocity y-velocity energy time/iter
# Divergence detected in AMG solver: temperature -> Increasing relaxation sweeps!
Error: Divergence detected in AMG solver: temperature
Error: Divergence detected in AMG solver: temperature
Error Object: #f


I don't know what it means and how to solve it, do you have any ideas??
Thanks in advance!
