Yeah, important for shell elements too. Consider a plate welded perpendicularly to another plate. Could you model that as quads where you have an element coming out of the page? So an edge is connected to three elements? Find neighbors will fail, but as will the entire notion of one neighbor pe

Ok - we've kinda talked about this before but now I really want to know what's involved... We would like to connect more than one element to the end of a 1D element. i.e we want a "branch" kind of structure. The motivation is 1D structural dynamics (like truss and beam elements). I know that fi
