Awesome Jozsef, thanks!

[@patelman2665]

Really happy after seeing you again. Thankyou sir.

Hey Mr. József Nagy, I wish you a happy weekend. I learn a lot from you, sir.

Jozsef, thank you!

I just wish snappy worked well with prism cells on the boundary layer 😢

[@OpenFOAMJozsefNagy]

Yes, layers are still an issue in snappy. Did you try cfMesh? Sometimes layers are better there.

[@matheusnunes970]

@@OpenFOAMJozsefNagy Yes. It worked better, but the free version of cfmesh is not even close to commercial softwares, sadly. I could only make 10 layers with barely passable quality, while my colleagues using ansys can easily pop out 30+ layers I guess it is a waiting game, or eventually helping improve the mesher myself. I did look for 2 months on the issue thinking the problem was with me. Eventually I found no other opensources meshers better than cfmesh for 3d

⁠@@OpenFOAMJozsefNagyby the way, thank you for your lessons on youtube. I specially followed the one on the rotating fan to be able to make a turbine myself

@@matheusnunes970 Great! I am glad it helped you!

Hi @@OpenFOAMJozsefNagy! is cfMesh free or does require license?

[@Gpto-nv7sm]

Hi! Before use the stl file we can use surfaceCheck to check the stl quality. I have a case with a stl very larger (like a 3 meters) and with thickness small (10 milimeters). Do you have some idea how i can do a mesh clear with openFoam? Or another open source software?

[@OpenFOAMJozsefNagy]

Not with OpenFOAM. Blender?

Hi, by the way, it wasn't just your hair that moved; it looks like the entire studio where you're recording the video did too, haha. Regarding the content, your old material might still be useful, and there are plenty of videos covering the same subject. May I suggest creating content on tackling real projects using OpenFOAM to solve real-world problems? This could involve customizing OpenFOAM solvers and cases.

[@OpenFOAMJozsefNagy]

The problem with this is that these projects are very problem specific problems which are interesteing to some viewers.
