Hi Dave

It is not currently possible to use the implicit surface mesher
if you have sharp features.
 However you can use for that the  tetrahedral mesher.
The 3d mesh generator behaves as the surface mesher
when it is launched with trivial criteria
for the mesh tetrahedra. Besides it has the advantage
to offer the possibility of handling sharp edges.

Hi Everyone, Is it possible to use features in the implicit surface mesher? 
What I would like to do is mesh an implicit surface (a level set) and have
the mesh respect a certain set of edges that are specified separately and
known to be on the surface.  I have looked through the manual quite a bit
and can only find the one (two spheres) example for a 3D tetrahedral mesh.

Thanks,
Dave
