QuaHOG
Quadrature for High-Order Geometries
QuaHOG is a repository of MATLAB functions for producing quadrature rules over high-order (polynomial or rational parametric) trimmed/intersected geometries in 2D. We plan to add 3D support as well.
This code accompanies the paper [1] Gunderman, D., Weiss, K., Evans, J.A.. Spectral mesh-free quadrature for planar regions bounded by rational parametric curves. Computer Aided Design, 130(102944) (2021). https://www.sciencedirect.com/science/article/abs/pii/S0010448520301378?via%3Dihub
The methods listed in the paper are in the SPECTRAL_quads.m (for spectrally convergent quadrature over 2D regions bounded by rational curves) and SPECTRALPE_quads.m (same behavior as SPECTRAL_quads, but exact for polynomials up to a pre-specified degree)
