[GiDlist] Node Numbering

Post by sujith gowda »

Hello,

I would like to know about some proper sequencing of node numbering in GID,
I tried with the options available as ReNumbermethod -2,-1,0,1,2..

What I need is, Node numbering for each and every surface i create
separately.
Like if I create 2 adjacent surfaces (2 squares) the node numbering I get is
1 3 5

2 4 6
but I need different numbers for the sharing node(3 & 4), as
1 3 5 7

2 4 6 8
(also in proper order)

Is it possible ?
Kindly suggest your views.

[GiDlist] Node Numbering

Post by escolano »

Two surfaces are connected if they share a common line, then the line’s nodes are shared by both surfaces (and a single node can’t have two identifier numbers)

If do you want two nodes, one by surface, then surfaces must not share any line.

You can ‘isolate’ each surface duplicating all shared lines and points with

Geometry-Edit-Uncollapse-Surfaces

Then all lines will have higherentities=1 (belong to only 1 surface), can see graphically with View-Higherentities-Lines

Then generating a mesh each surface will be meshed independenly.



The nodes for ‘neighbor’ surfaces won’t be located in the same location, you can try to force the same position with some trick, like set the number of division of lines (structured mesh for lines).



In any case the numeration of nodes won’t be ‘by surface’ with any RenumberMethod.

As a second trick it is possible to associate the number of the geometric entity to the mesh entities generated from this entity. Do do it must define in a problemtype a condition assigned to geometric entities, with a special automatic field #Num# that is filled when meshing for the mesh entities with the number of the geometric entity (e.g. to know which elements belong to each surface)
