I would as much as possible like to avoid copying all-to-one -> one-to-all. Originally I was using DMClone but have now discovered that this is a shallow copy. I am trying to add distinct sections to an existing mesh (not refine) and would like the new DM to:</div><div class=""><br class=""></div><div class="">a. Be distinct from the old one (i.e. not a super or sub dm).</div><div class="">b. Not “know” about any additions. i.e. the new DM should act as if it was brand new.</div><div class="">c. Carry over any other appended objects such as petscds’es, fe’s, fvm’s, labels etc. </div><div class=""><br class=""></div><div class="">If I had to do it by hand, exactly what can I copy directly and what needs to be recomputed, especially in parallel? Getting and setting mesh coords, dimension, cones are somewhat straightforward, but what about the SF's, PetscSections, and others? </div><div class=""><br class=""><div class="">
