Hi everybody, Does deal.II provide a way to use Gauss-Lobatto-Chebychev quadratures when using FE_DGQArbitraryNodes<2>? Specifically, I want to integrate functions f(x) using Lagrange polynomials on the GLC support points. The quadrature there is usually defined with a weighting function, as \int f(x) = \int w(x) \Phi(x) ~= sum a_i^GLC \Phi(x_i).
In order to use this in 2D, I need weights that are scaled with the weighting function, as a_i=a_i^GLC / w(x_i), otherwise they will not sum up to 1. Is this only possible via defining a new quadrature? Even when defining the weights a_i in a new quadrature, their sum would only appoximate 1, preventing the quadrature from being extended to 2D. What is the best way to approach this issue in deal.II, and in general?
