Hello Foamers !

Here is a part of a mesh I am working on.

As you can see, the leading edge is not refine as told.
The rest is fine even with supplementary layers.
I forced the minRefinementCells to a huge number to see if it changes anything. It didn't :

minRefinementCells 500;
refinementSurfaces
{
wing_p1
{
// Surface-wise min and max refinement level
level (8 8);
}

}

Do someone have any idea to correctly mesh this surface ?
Thank you, have a great day !

Hi,

If you have a high value of minRefinementCells, then snappy will stop refining your mesh if the number of cells to be refined are below the minRefinementCells number.

So if you want snappy to mesh more, then you will need to make minRefinementCells smaller.

Also, have you tried using featureEdges to capture the leading edge to your satisfaction?

Hope this helps.

Cheers,
Antimony

I reduced the number, it changed nothing.
I was already using the SurfaceFeatureExtract in my meshing but the angle was set to 150°. I pushed it to 179° and remeshed. The meshing is perfect now.
Thanks Antimony!
Cheers
