Hi Foamers,

i want to generate layers in a small gap (1mm).
Here are my settings, with those i can see some layers:

hex (0 1 2 3 4 5 6 7) (30 30 20) simpleGrading (1 1 1)

// In z direction, i have to define 20 cells. With more or less cells, i can not see any layers.

// Surface-wise min and max refinement level
level (2 2);

//levels 2 3, 3 4... are not possible.


mode inside;
levels ((1E15 1));

//level 2, 3... is not possible.


As u can see in the picture, the mesh is not fine enough. The surface of the rough stl is also not satisfactory.
I changed the layer thickness to false and defined the thickness (min and average) manually to the smallest size (without improvement)

Mabye someone is experienced in meshing a micrometer region, or have an idea.
Tomorrow, i will post my complete snappyDict.
