[GiDlist] A better Sphere mesh?

[Oguz Tanzer]

Hello,
I generated a mesh of a Sphere using the ready-made
"Sphere" Geometry in the toolbar and the resulting
mesh has more triangles (seen on the boundary) near
the "circle lines" defining the sphere.

How can I get a more "homogeneous distribution" of the
triangles on the sphere?

Can it be done with some adjustment of mesh quality
parameters? Or anything else?
Thanks.
Oguz-

Try to assign manually the same unstructured mesh size (menu
Meshing-Assign unstruct. sizes) to all entities: lines, sufaces and
volumes, and unselect the "automatic correct sizes" mesh preference
(utilities-preferences-Meshing).

You can also select the preference to mesh using "Rsurf" instead "Rfast", to
try to obtain a best triangle quality in
non-uniform parameterized surfaces.
