A Blended Quadrature Approach for the Accurate Integration of the Gradient of the 3D Green's Function

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

This paper presents a partially closed form and partially numerical method for the accurate integration of the singular integral related to the gradient of the 3D Green's function. Verification examples are provided and compared with a brute-force integration using an arbitrary precision library.
