Hi Philippe, you may want to have a look at the utility "connectivity" routine. Amongst other things, it will identify the boundary nodes in a mesh.

Author comment: v24 was posted to resolve a licence conflict. The Mathworks no longer allows code to be released under a GNU GPL, so this has been removed for v24.

There are some (minor) revisions to the code, based on user feedback. Specifically, v24 may be slightly slower than v23, but should generally produce higher quality meshes, especially for complex geometries.

Nice, used it in a problem with an unstructured grid and worked perfect.
