Hi everyone,

I'm using the triangulation method *make_mesh_3()* to tetrahedralize any 3D
mesh with *detect_features() *to make tetrahedron as big as possible. That's
why I use this criteria : 

*Mesh_criteria criteria( facet_angle = 20 )*

In release mode it works but in debug mode it generates the following error
: 

*terminate called after throwing an instance of
'CGAL::Precondition_exception'
  what():  CGAL ERROR: precondition violation!
Expr: sp > 0
File:
/net/rnd/src/cgal/CGAL-4.0.2/linux-x86_64-gcc-4.1.3/include/CGAL/Mesh_3/Protect_edges_sizing_field.h
Line: 629
Abort*

So, I add some parameters to complete the criteria like *edge_size = 5 * and
*cell_radius_edge_ratio = 4 * to have big tetrahedron but it doesn't work
like before, in release mode. 
Any idea to help me fix this problem setting the parameters correctly ?

Thanks a lot

Julie
