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.

Hey did you try the tutorial "blocking of two types of wings"?

Thanks for replying Far,
I'm not sure what tutorial you mean?!
Did you check my blocking?

tnx

Yes I check it. You can get quality > 0.6 and right now you have < 0.3.

You just have to move vertices to get the better quality.

Thanks Far,

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.
