Hello everybody. I need a help in a matter. I am going to simulate a 3d wing so I need to cooper mesh for domain and I should use ''tri-pave'' type for face. I mesh easyly front face using tri pave type but when I use the link face mesh, back face is really bad. I need to use link face to cooper mesh volume but link face is really bad. Here are some pictures. Is there anybody help me please? I really appreciate...

Do you also have the problem without face mesh linking?

Thanks for replying realy thank you... Yes also I have problem. Trying both without link face mesh and link face mesh to cooper mesh, gambit gives error. I have tried also using edge link or seperately mesh face but the same problem facing.

Then I would create a surface surrounding your wing, and split your domain with it.
Doing that, you willl have more control on the mesh near the wing, and also you should avoid the effect you described.
Mesh the volume near the wing with hexa

Shared geometry pictures already surrounded near wing,real wing inside the that domain. For a long time I tried to mesh just wing and after I created surface surrounding like I shared geometry but same problem.I cant go forward anymore.I tried many things all I can do (changing surround geometry). This is the link my file if you look and help me really appreciate..thank you so much.

upload your file on dropbox or whatever, because your link gives me lots of undesired popup.
I am at the office...

Alright,
There is a tolopology issue.
One workaround is to split your geometry 1 or 2 times along the z-axis.
It solves your problem

No time to mesh something wonderful...

Thank you so much for response. You used quad-map scheme but my prof told me it should be tri-pave... Is there any other way to do that by using tri-pave?

yes you can do it also with tri-pave .

I have tried many times but failed, even after you told me I tried it by splitting z directions but not successful. If you have time could you do and upload here, I would really appreciate it
