Hi Matt,

I have inlined some responses below.

That's right, the common contour filter, contours each patch individually
and therefore
you get cracks across patch interfaces. If you don't care much about
producing a water-tight
contour surface (I am assuming your data is 3-D), one potential quick and
dirty solution could
be to extrude the boundaries of each patch (let's say by one layer of
cells) and contour that. This
approach will still produce cracks, but depending on your end goals, it
might be sufficient.

Yes, that is contouring the dual and it will stitch the contours across
patch interfaces. However, to the best of my knowledge this is intended for
non-overlapping AMR, which is probably why you are running to problems.

Would it be possible to share a sample dataset with us? I have worked on a
dual-grid algorithm for overlapping, patch-based AMR and I can try to look
in to this.

Best,
George
