Default energy model don't converge

I'm working with three flow models: energy, continuity and k-e viscous model. But I can't obtain the convergence with all models, only with continuity and turbulence. What is wrong? I think that my mesh model is fine but I don't know what happen.

Hi Alex,

I noticed in section 26.24.3 of the User Guide for AMG controls a reference to energy equation divergence. On the last page of the section under 'Fixed Cycle Parameters' it mentions increasing V-cycle post relaxation sweeps to combat this.

I don't know if it is applicable in your case but maybe give it a shot.
