I have a question about the total number of quadrature points in the triangular element: results from the chk file show that each element has totally 30 quadrature points (instead of 31), and coordinates of these points are plotted in the following figure. It seems that these quadrature points don't include the singular point. I wonder why is this the case and could someone kindly recommend references about this issue? It will help me a lot to understand the results generated by Nektar++. Thanks a lot. Best wishes, Yong Wang [image: image.png]
