Hello Dimitrios, developers, I’ve written such a code some time ago, conforming adaptivity using Delaunay triangulation. Is that that you need? It was working well in my case where I had to solve elliptic and parabolic problems with first order continuous galerkin, P1 lagrange basis. I’ve sent a link to a downloadable example in this mailing list. Did you have a look? Developers? https://sourceforge.net/p/libmesh/mailman/message/35758424/
The link isn’t working anymore but if you need I can repost it or, Dimitrios, just come to my office ;) Regards, Giacomo Rosilho de Souza ————————————— EPFL SB MATHICSE ANMC MA C2 637 (Bâtiment MA) Station 8 CH-1015 Lausanne Il giorno 3-ott-2017, alle ore 16:44, Roy Stogner <[email protected]<mailto:[email protected]>> ha scritto: On Tue, 3 Oct 2017, [email protected]<mailto:[email protected]> wrote: I would like to ask if libmesh can support conforming mesh adaptation. Technically, "can support" - yes. One of the consequences of the "toolkit, not a framework" philosophy is that users can do a lot of things without specific library APIs to do them, and looping through elements to split some of them would be a good example. libMesh will even do a few things to help with that, like reconstructing neighbor topology for you if you don't do that on the fly yourself. But "can provide" - no. Currently the only refinement types built into the library are isotropic h refinement with hanging nodes, isotropic p refinement on hierarchic element types, nodal redistribution, and mixtures of those. If you do write conforming mesh adaptation code, though, and it's generic enough to work on others' problems (even if it's only for triangles/tets), we'd love to incorporate it. --- Roy ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org<http://slashdot.org>! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list [email protected]<mailto:[email protected]> https://lists.sourceforge.net/lists/listinfo/libmesh-users ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
