Hello, I want to know how to handle hanging nodes. I read DofMap::heterogenously_constrain_element_matrix_and_vector() and found comments like // The constrained matrix is built up as C^T K C. // The constrained RHS is built up as C^T (F - K H) Are there papers or books on the algorithm used in libmesh? Or what I can do is just to read the code? Hello. For the constraint matrix C, here's a link to discussions on this list and Libmesh-devel a couple of years ago. I found this extremely enlightening (thank you very much to the original participants) and so have it bookmarked. I don't know of a reference in the published literature. https://sourceforge.net/p/libmesh/mailman/message/28886234/ ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
