Skived Fin - Salome Mesh help

Hello everyone,

I am completely new to Salome (I started to use it two days ago), and I would like to have some tips on how to create good meshes for OpenFoam (used with Baram Flow).

For now, I find Salome to be much easier to use than SnappyHexMesh, especially when creating boundary layers in 3D.

For my small project, I want to simulate a skived fin used in heat exchangers (to extract Colburn and Fanning factor). I was able to produce a mesh from Salome, but I don't find it to be particulary good. How could I improve it for 3D is used NetGen and for 2D Gmsh)?

Since it is a very small fin (the volume is 2.4 mm x 12 mm x 17 mm), the flow around it is laminar. So no need of very fin boundary layer like with RANS k-omega SST.

The fin is tilted, so I created a fluid volume also tilted (and I use transitional periodic boundary conditions for the left/right sides). I already ran 2-3 simulation, and was able to it to converge easily (the mesh was more refined than the ones in the pictures, but it was very similar).

Thank you!
