Question about Quadrature elements and their integration into variational forms

Hi. Just a regular user here. First, Read before posting: How do I get my question answered? (you need a MWE if ever you want an answer. Following the requests of those who are helping you–for free–is a very good advice–because I say so :stuck_out_tongue: ). Secondly, all sort of things can go wrong. I’ve been there. Good luck.
