Hello. I am modelling Mixed convection model with laminar flow.
If I leave default under-relaxation factors all values starts to grow continuity 1 and more... So I have reduced the values of it like this: Pressure 0.3 Density 0.5 Body forces 0.5 Momentum 0.7 Energy 0.5 And I get these kinda iterations (attached as image). My question is. What I should do. Can I say that results are converged around 4000 iterations. At that moment it seems like converged value by most of converging criteria, but that later growth is mystery to me, not sure what even to do. Or I should change under-relaxation factors? |
