Great post here @jousefm ! I made a simple simulation of an airfoil just to investigate if I could get a good Y-plus value after reading this post. Link to my project Mesh Airfoil with 1 meter chord length Background mesh box = 7x3x3 m Simulation settings Turbulence model = k-omega SST Fre…

Hello @chupaka , I had a quick look into your Cessna project and I believe I found the issue. Even though the first layer height value is defined as 3e-6 m, you’ll realize the resultant average first layer height is around 1e-3. This is actually the consequence of the small feature suppression para…

Hi @Filiptheking , The layers look good so far, but you will see some interesting problems as I describe below. Namely how ParaView shows y+ is less than 1 but it actually isn’t. [image] Filiptheking: As you can see, the Y-plus seems to be below 0.05 for most of the wings surface. Is it normal…

Thank for your answer @Get_Barried ! Yes, I can see that I made some errors. However, in the mesh that is named “Y+ Experiment 2”, I did put in the correct final wall thickness of 0.0016. I should have removed the first mesh, but I forgot it, sorry for that. Also, I used the first mesh with the…

I have the same problem but in a different direction. I aim to y+ =0,2, but in results I see around 50.

Cool, thank you. Could you correct information about small features suppression in note when someone change value of it. I thought that it works only for surface mesh!

Hi @Filiptheking and sorry for the delayed feedback.

Will have a look at this and either @Get_Barried or me will get back to you!

Cheers!
