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 »

Submitted: Probing protein orientation near charged surfaces

Figure from our paper on probing protein orientation near charged surfaces.

First submitted: 31 March 2015. Submission of split papers: June 7 and June 12.    UPDATE: The material in the original manuscript was split in two papers, submitted to different peer-reviewed journals. The editorial decision on the first submission was that the paper was out of scope for the journal, which led us to reorganize... Continue »

Ph.inally D.one!

Congratulations Anush! Friends surprised Anush with this lovely cake to celebrate his accomplishment.

Two Barba-group Ph.D. students successfully defended their doctoral dissertation this week. Congratulations to them! Anush Krishnan came to Boston University on 2009, after completing a Dual Degree (B. Tech & M. Tech.) in Aerospace Engineering at IIT Madras, Chennai, India. He has worked on development of immersed boundary methods (IBM) for solving Navier-Stokes equations at moderate... Continue »
