Submitted: Inexact Krylov iterations and relaxation strategies with fast-multipole boundary element method

sketch of quadrature-points clustering on boundary element method

Submitted: 19 June 2015 This paper presents a method to algorithmically accelerate boundary element methods. The fast multipole method (FMM) is already used in this context to obtain O(N) computational complexity while solving a dense linear system. Using relaxed-accuracy matrix-vector multiplications in a Krylov solver, we can achieve speed-ups in the order of 4x... Continue »

After submission for peer review, and with the preprints on arXiv, we also make public the manuscript source files in the GitHub repository. View // Reply // Retweet // Like
