Smooth-Rigid-Body Contact as a ReLCP: A Recursively Generated Linear Complementarity Problem

Bryce Palmer, Hasan Metin Aktulga, Tong Gao

This paper reformulates complementarity-based time-stepping for frictionless nonsmooth contact between smooth rigid bodies as a recursively generated linear complementarity problem…

Analytic preconditioners for decoupled potential integral equations and wideband analysis of scattering from PEC objects

J. A. Hawkins, L. Baumann, H. M. Aktulga +2

Many integral equations used to analyze scattering, such as the standard combined field integral equation (CFIE), are not well-conditioned for a wide range of frequencies and multi…

High Performance Evaluation of Helmholtz Potentials using the Multi-Level Fast Multipole Algorithm

Michael P. Lingg, Stephen M. Hughey, Hasan Metin Aktulga +1

Evaluation of pair potentials is critical in a number of areas of physics. The classicalN-body problem has its root in evaluating the Laplace potential, and has spawned tree-algori…
