Abstract
This paper presents a novel non-iterative numerical quadrature method designed for integrands with singular/irregular behaviors well-approximated by generalized polynomials with real exponents potentially combined with logarithmic singularities. The procedure can be implemented easily at negligible computational cost and memory in finite methods for Multiphysics computing based on PDE and IE formulations.
