[Gmsh] mesh a cylinder with hole

[jean pierre aubry]

hello Alberto and Mikail

i do not agree with your method
Surface(2) is not cylindrical, you ca see that if you increase r

the intersection of two intersecting cylinder cannot be defined as a
(plane) circle it is a 3 D curve like in the enclosed pics one large
pipe intersected at 45° by a smaller one (smaller pipe not shown here)

if you want i can post here the bit of code that do it
