Reply To: turbulent viscosity ratio and convergence issues

[abdullahhassan]

Thank you Rob, 

One thing I need to add: with divergence, sometimes temperature limited to 1.00e1 warning also appears and the divergence happens with divergence detected in AMG solver: k or epsilon or vof and finally Floating point exception error came. 

Will these things also highlight to some issues?

 

Eulerian has Coupled and Phase Coupled Solver and I am trying Phase Coupled Solver right now.

Local Flow Field means checking of velocity vectors inside domain? As the turbulent viscosity is increasing or decreasing so its contour is also changing. how should I know which mesh to improve and from where should i start to improve this divergence?
