Refining quadrilateral and hexahedral element meshes

[fcdiass]

Hello everyone!

I would like to know GiD offers some way to refine meshes as proposed by Robert Schneiders in his work “Refining Quadrilateral and Hexahedral Element Meshes”.

Here we have some examples of this type of refining in 2D quadrilateral meshes:

… and in 3D hexahedral meshes:

Sorry, GiD cannot do this kind of hexahedra refinements, with pattern of edge subdivisions 1:3
The octtree mesher is doing internally a similar subdivision with pattern 1:2, but in any case it is an internal feature not accessible at user level.

Thanks for your quick answer! Currently, I am doing this transition manually (almost drawing one by one element).

Instead of manually you can do it at Tcl scripting level

e.g. can ask the current mesh for example with
GiD_Info Mesh

and can create new nodes and elements with the command
GiD_Mesh create|delete|edit|get|list

see GiD help on Customization->Tcl/Tk extension
