[Gmsh] Error : Could not restore all edges/faces ....

[Jose Paulo Moitinho de Almeida]

Hello

While "playing" with gmsh (1.41.0) I got this problem when I tried to get a 3d 
mesh of a cube. 

.....
Info : Final check: 11 missing edges, 15 missing faces
Info : ===================================================
     : Surface coherence results (number of intersections)
     : 58 EV, 14 EE, 23 FV, 13 FF, 1 FE, 0 EEE, 0 EEEE
     : ===================================================
Error : Could not restore all edges/faces
Error : Surface recovery failed (send a bug report with the geo file to 
<gmsh at geuz.org>!)
Mesh 3D... (final)
Nod=70 Elm=329
Vol(2.74427) Conv(3.4641e+11->0.8)
.....

By changing the length from 0.5 to 0.7 I managed to solve my "problem", but 
perhaps this is a good test case...

Regards

Ze Paulo
