Re: [deal.II] finite element with shape functions having delta_ij property at quadrature points

> I asked myself why the constructor of FE_Q wants a quadrature object whos first and last qp is at zero and one, respectively? Because it is a continuous element and dofs at 0 and 1 are assigned to shared entities (vertices, lines, quads). Peter On Monday, 16 August 2021 at 22:03:44 UTC+2 Si

"You've already found this: Both the FE_Q and FE_DGQArbitraryNodes classes have constructors that create shape functions based on this information." The latter is the element I was looking for. The problem with the former is that the first and last quadrature point has to be located at zero and o
