Gambit Mesh A Cylinder
 

I want to mesh a cylinder of dimensions:

350 micrometers Diameter
40000 micrometers Height

I firstly determine a mesh for boundary layer for upper and lower circular surfaces of the tube.

Do you know how to control the mesh size ALONG the height?

I means I prefere a refined mesh for the upper and the lower surfaces and a much more coarse for the remaining surface.

In fact, I have several tubes to assembly at last and they are not centered.

Thanks in advance!
