Trouble generating a mesh with high number of borders

[Pwaroquier]

Hello,

I am generating meshes with FreeFEM that contain a huge number of borders. When I try with a few borders, it works, the mesh generates and I can plot it.

However, when I increase the number of borders, the plot does not show up. It simply does not generate the triangles for the mesh, it stops after the nodes :

You can see that I do not receive any error messages, it just stops.

Has someone already met the same problem ? Do you know where it comes from and I can I fix it ?

Thanks in advance,
Pierre

You will find below a part of my code for clarity.

Thanks again,

Pierre
