open TELEMAC-MASCARET The mathematically superior suite of solvers

I have extracted the node numbers of boundary nodes in BK. Is there a way I can extract the xy coordinates of the same boundary nodes in BK or otherwise.

Thanks in advance

In BlueKenue, you can obtain node coordinates in extracting polylines of the mesh boundaries with
Tools > T3 Mesh > Extract Edges (Shorelines).
Then you can save it as an xyz or i2s files for example (be careful it contains all the boundary segments, including the islands).

If you need to have both nodes and coordinates, I would write a short script to extract them.

Hope it helps,
Luc

Thanks for the reply. I need the corresponding node numbers also along with the xy coordinates for all the boundary points.

Hi,

Saving the mesh as a "Trigrid Neigh File" will give you the desired info.

The columns in the file are defined as follows:

1. node number
2. X
3. Y
4. Code (0=interior,1=outside edge,2=island)
5. elevation
6... neighbouring node ids

Hope this helps... Martin

Hmm, found a solution already?
I'm facing the same problem. The ngh file is close, but doesn't include the boundary number. Could use this to extract the combination, but maybe you've found an easier option?

Hi,

In that case you could do a table join on the contents of the ngh and conlim files.
