Hi Mike,

Gmsh will not remesh these STL faces, though. It's something we will
reintroduce at some point, but the remesher is not ready yet.
...
Cheers,
Dave

Dear All,
I have an STL model which I load (with the `Merge' command) into Gmsh.
The model is a boundary representation (a shell).
When meshing this model (and others), the mesh on the surface of the
model seems fixed and unaffected by the characteristic length settings.
Any suggestions how to control this surface mesh (preferably with fields)?.
Here is a simple script which loads `sph.stl', a sphere shell in saved
STL format:
Mesh.CharacteristicLengthFromPoints = 0;
Mesh.CharacteristicLengthExtendFromBoundary = 1;
Mesh.CharacteristicLengthFromCurvature = 0;
Mesh.Format = 1;
Mesh.CharacteristicLengthMin = 0.01;
Mesh.CharacteristicLengthMax = 0.05;
Merge "sph.stl";
Surface Loop( 1 ) = { 1 };
Mesh 2;
Save "sph.msh";
Cheers,
Mike.
