Hi, Laurent, 

      I have another question. Yes, because of the working directory problem, so the program read a unexist file and  I got the !empty() exception (The AABB_tree is empty). The working directory of qt-creator launching the program is 

/home/huayiwei/work/program/meshGenerator/example/Regular_triangulation/Mesh_3/build/

But the data is in 

/home/huayiwei/work/program/meshGenerator/example/Regular_triangulation/Mesh_3/data/

When the program use following code to input domain data:

 // Create domain

  Mesh_domain domain("data/fandisk.off");

it actually try to read the following file:

/home/huayiwei/work/program/meshGenerator/example/Regular_triangulation/Mesh_3/build/data/fandisk.off

which doesn't exist. 

My question:  when the program try to read a unexist file, it should directly 'complain' about it, isn't it?

The difference must be the working directory where the program is launched. It
must be the one of sources, in your case:
/home/huayiwei/work/program/meshGenerator/example/Regular_triangulation/Mesh_3/
