Can you please send us your command line, and the complete log,
until "Segmentation fault" happens? Are you using the Polyhedral_mesh_domain constructor that takes a filename as parameter? Le 14/04/2016 13:52, Timothée Nicolas a

Good question.
I am using CGAL-4.7 2016-04-14 20:49 GMT+09:00 Andreas

Are you both sure to use the same releases of CGAL? andreas On 14/04/2016 13:48, Timothée Nicolas wrote: Thank you for your answer. So you say you were able to produce a valid out.mesh file with the .off file I suggested ? I just checked on my Ubuntu computer, and it does the same as this afternoon at work on a Mac OS X. The error message here is Erreur de segmentation (core dumped) If I remember correctly, on the mac, it was something like Segmentation fault:11 I have added the verbose line you sent me, and it does not tell me anything else... Timothée 2016-04-14 19:45 GMT+09:00 Jane Tournois < <mailto:>>: Hi Timothee, I could not reproduce your seg fault. You can try to add the following macro definition on the very first line of your cpp file : #define CGAL_MESH_3_VERBOSE and then post the execution log? This could help you or us find the error. Also, you mention an "error message". What does it say ?

I figured that the easiest way to do this was to use a .OFF file of my boundary, which does not seem too difficult to produce, and feed it directly to this example program http://doc.cgal.org/latest/Mesh_3/Mesh_3_2mesh_polyhedral_domain_8cpp-example.html Before taking on my actual boundary surface mesh, I need to understand exactly what I am doing, so I tried replacing the file elephant.off with the following simple .off file representing a pyramid OFF 5 6 0 0.0 0.0 0.0 1.0 0.0 0.0 1.0 1.0 0.0 0.0 1.0 0.0 0.5 0.5 1.0 3 2 1 0 3 3 2 0 3 0 1 4 3 1 2 4 3 2 3 4 3 3 0 4 Unfortunately this produces a segmentation fault when making the mesh. I have no idea what causes it to malfunction. Anyone has a clue ? I have also tried with a simple tetrahedron or a cube with each face cut into two triangles, same error message.
