How to make a 3D Cylinder Mesh?

[Leo]

Hi
Consider this:

from dolfin import *
from mshr import *

#Making a cylindrical geometry
cylinder = Cylinder(Point(0, 0, -1), Point(0, 0, 1), 0.5, 0.5)
geometry = cylinder

# Making Mesh (40 corresponds to the mesh density)
mesh = generate_mesh(geometry, 40)

# Save the mesh
File("cylinder.pvd") << mesh

Here is the mesh:
