[GiDlist] Node Numbering (2 surfaces)

Post by sujith gowda »

Hello all,

I could get a sequential node numbering for a structured mesh as per the
solution given last time by Mr. Enrique With renumber method = 2.

But if I place another surface over the background mesh. I see that numbers
are distributed among 2 surfaces.

What I require is - as attached sketch.

Such that, Surface 1 should have a structured mesh with sequential node
Numbering from 1 to n
and then for the second surface node numbers should start from n+1 to m in
sequential manner.
Same for the Element Numbering.

Note:
I am able to get this kind of separate node numbering for 2 surfaces with
renumber method = 1.
But it is not sequential as we get with renumber method = 2.

Kindly help me regarding this,

Thank you,

The renumber method=2 renumber all nodes scanning ‘aligned nodes’ in x ,y, z directions based only on node’s coordinates.



You cannot have the numeration you want directly with GiD,



You must renumber the GiD mesh by yourself outside GiD, or inside with your own Tcl procedure (it is possible to register a Tcl procedure to be called automatically just after GiD generate its mesh)



To implement this kind of numeration must do something like:

1-find connected groups of elements, in your case there are two groups, one by surface.

2-for each group do a renumeration ordering nodes in a similar way of our renumber method=2: find rows of nodes with ‘near same’ y, and order in the group by increasing x, and order the rows by increasing y.
