Determine boundary elements

Jan 15, 2016 at 10:02 AM

Once again thanks a lot for the good work you’re doing with this library!

I am trying to get a list of the elements limiting with a specific contour line.

For instance in your example “refining regions” I'd like to get a listing of the triangles which are limiting with the outer circumference.

I’m still not completely familiar with the library. Is there any short cut to achieve this?

Sure, take a look at this example.

You'll have to download the latest source code to get the VertexCirculator class.

Thank you for the example!

I was able to define the boundary elements

The fact that you can get the elements adjacent to a segment is very useful

i just need to plot contour graph using button (like you used triangulate and smooth)

  1. Why not open a new discussion for a new topic like contour plots?
  2. The UI is plain Windows Forms. If you want to add a button, do it in Visual Studio's Designer. If you don't know how to do that, get a book about Windows Forms (or find a tutorial online).
  3. There is a simple approach to plotting contours, see It can be easily adapted for unstructured meshes.
