Hello all,

It seems that GMSH (with `gmshload`) cannot load triangle whose the measure is smaller than 1e-8.

```auto
Triangles 40 1227 127 54
mes=4.64389e-09
bug : mes < 1e-8 !

```

Had someone already faced the same issue ?  
And how this problem has been solved ?

Thank you in advance,

Best regards,

Loïc,

You can change the code in gmsh.cpp line 436

```auto
              if (tff[it].area < 1e-8) {
                cout << "bug : mes < 1e-8 !" << endl;
                exit(1);
              }

```

or make a homothety on the mesh to remove this problem.
