[Gmsh] Wrong elements

[cristini paul]

Hello,

I am facing a problem with Gmsh. I am generating a 2D mesh (quadrangles) 
which consists in many disks put inside a box.

It is working for a configuration with ~ 1000 disks but unfortunately I 
have a problem when trying to generate a mesh with # 3000 disks.

I use the external python API  to generate the .msh file but my tool 
which detects elements with negative jacobians find some although Gmsh 
didn't mention anything. After reading the .msh file with the GUI I 
finally found that there is indeed problems at the places detected by my 
tool.

I enclosed screen captures showing the situation.

Do you have an idea of what's going on ?

Thanks

Paul
