Hi All,

I am new to CGAL and has a question regarding 3D mesh generation from a 
specific domain. The code file cgal_mesh.cc is attached with two data 
files included. If I use fandisk.off data file as the domain, it works 
fine. But if I use T3d_rec.off as the domain, it crashes with error 
information as below.

terminate called after throwing an instance of 'CGAL::Assertion_exception'
  what():  CGAL ERROR: assertion violation!
Expr: !r_tr_.is_infinite(*cell_it)
File: /usr/include/CGAL/Mesh_3/Refine_cells_3.h
Line: 385
Aborted

The latter data file T3d_rec.off is just a simple hexahedron with 
similar scale as fandisk.off.

Could anyone let me know what is wrong with the code, especially the 
mesh criteria.

Thanks and regards,

Danyang
