Dear author Through your explanation and the explanation file you uploaded, I have a deeper understanding of the program. When I ran the program, I found the parameter m_elOrder can be used to calculate the Gauss2 to determine the accuracy of the integration. I want to ask you, what should I do if I want to improve the accuracy of integration? Do you need to change the triangular element from three nodes to six nodes when Gmsh divides the mesh? But I didn't find the relevant operation in Gmsh software. I hope you can reply to my email when you have time, and look forward to your reply. I wish you a happy life and smooth work.
