Hi all,

Is it possible to identify and extract only the boundary nodes from a mesh? Also, related to this. what is the relationship between elements and node numbers? I have a mesh but not the original .xyz data and want to see which nodes align with the boundaries.

Reading the *cli file 1) is clearly node # for xy based on the original .xyz, 2) the elements, and 3) the prescribed boundary conditions with associated element.

There's a clear sequential relationship between the elements and nodes in the file. Is it possible to see which elements are associated with which node?

Thanks

Hi

I think the description of the *.cli file is well done in some documents...
The numbering is made continuously from the south west point (minimum of X+Y) in the counter clockwise direction... and if there is some island, the boundary nodes are added after with the same rule (minimum X+Y) but clockwise.
In Blue Kenue, you could extract easily the shoreline from a mesh but I don't know if this is what you want.

Regards

Hi,

Thanks for your response!

My mesh is of a river, the solid boundaries of which represent the channel. If the shoreline is also a solid boundary I hope it should work. What method should I look at?

Many thanks

Please ignore the above message. I see there's the Tools > T3 Mesh > Extract Edges (Shorelines) option.

Thank-you for making em aware.

Kind regards.
