Interior boundaries

[griff10000]

Does meshpy have a way of identifying interior boundary nodes?

For, say, the given example of a rectangle with two circular holes.

info.set_holes([(0, 0)])

Thank you for your reply.
I wonder if you could expand your answer to provide an example of how I can extract node indices for hole boundaries.

I have been using examples from jw_meshtools.py

Look at facet attributes.

Thanks. I have now found a solution using jw_meshtools.py
