Hi, I'm a new user. I'm wondering how to use spectral quadrilateral elements based on tensor product lagrangian polinomials on Gauss Lobatto Legendre points. Searching the mailing list and the classes, I found two different constructors to do this, namely: fe_Q(GLLpoints) (with GLL points on [-1,1] which must be shifted to [0,1]) or fe_DGQArbtrarynodes(...)? The latter solution seems to be the recomended one. Why do I need to resort to DG methods since I need a conforming triangulation?
Thanks, -- Stefano
