Alex07 New Member Alexandru C Join Date: Jun 2015 Posts: 3 Rep Power: 11	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! Muhsen Mahdi likes this.
