Hello,
I'm new with Fluent, so I have some problems. Actually, my analysis is very simple. laminar and cold flow. I generated two different mesh for this analysis. the mesh number for one of them is 250000, the mesh number of other 1100000. When I used the model which has 250000 mesh number, I don't have any problems. It converges. On the other hand, other model doesn't converge. I consider that the mesh quality is enough. maximum skewness is 0.79. I use same boundary conditions for two models. How can I solve this problem? Thank you. |

much number of mesh didn't mean better result often. you face to truncation error

i guess jumping from 250000 to 1100000 is big. 500000 is enough for next level
