[ GiDlist ] Request for advice on meshing parameters

[Ramon Ribó Rodríguez]

Hello,

To obtain meshes that describes correctly the geometry with a minimum of
elements it is possible to use:
Meshing-Assing unstr. sizes-By cordal error
To change the meshing size transitions, change the factor:
Utilities-Preferences-Meshing-Unstruc. size transitions
To assign meshing sizes to part of the geometry use:
Meshing-Assign unstruct. sizes

Documents on GiD are basically:

GiD User Manual
GiD Reference Manual
Tutorials
Some examples of 'problemtypes' included with the GiD installation.

To be able to help you in the surfaces item, I would need a more detailed
information.

Best regards,

Hi all,

I have recently started evaluating GiD, and am rather impressed, so far.

I am performing rather complex CFD work - with a 2d mesh consisting of 1
NURBS surface, consisting of an exterior closed boundary, with 750
enclosed closed boundaries.

Is someone able to provide advice on suitable selection of meshing
parameters, in order to both optimise meshing time, but to also give
reasoably optimal meshes.

Is there a way to say separate a complicated mesh into separate
"surfaces", and mesh each in its own optimal way? Will the mesher ensure
grid continuity between these surfaces?

Any tips & advice in this area would be welcomed...

Are any papers avalable beyond those in the excellent tutorials?
