Hi friends,
I have generated two grids around a wing which one of them is coarser. Problem is here that I can not manage to converge continuity residual beneath 1e-3 in Fluent for both grids. I have even tried dp solver but it does not make any change. The residual begins to become a straight line close to 1e-3. Other residuals are just OK. I have previously produced grid around such geometries using Gambit. But ICEM seems to be annoying me a lot. I have uploaded the grid files and I will appreciate any help. tnx. |

I think I have to still work on my grid. just two more questions: 1-I don't understand "Quality" criterion. would you please illuminate it for me?! 2-I have very high aspect ratio cells (over 5e+4). Could it be a source of convergence issue?? Thanks for helping. |
