I have a part that I can only mesh with max. element size of 2 using Netgen. It fails to generate meshes with all other element sizes. I would like to reduce the element size so I can have 2 or 3 elements in the thickness direction.
I appreciate your help - Hooshsim

This Step is suitable to extrude or even revolve.
Use a good quality algorithm to get a surface mesh.
I suggest a Gmsh custom command.
Mesh.Algorithm = 11;
Mesh.MeshSizeMax = 2;
Mesh.MeshSizeMin = 2;
Mesh.MeshSizeFactor = .5;
Mesh.ElementOrder=2;
Mesh 2;
Once meshed, hallow, clean one of the surfaces and extrude the remaining one with the desired number of elements.
The minimum number of elements per curvature and edge can’t be less than 1.
By other hand, your step has different parts. Try merging them before exporting.
It shows some intersecting elements.
