Random Batch Ewald Method for Dielectrically Confined Coulomb Systems
Zecheng Gan, Xuanzhao Gao, Jiuyang Liang +1
Quasi two-dimensional Coulomb systems have drawn widespread interest. The reduced symmetry of these systems leads to complex collective behaviors, yet simultaneously poses signific…
Fast Algorithm for Quasi-2D Coulomb Systems
Zecheng Gan, Xuanzhao Gao, Jiuyang Liang +1
Quasi-2D Coulomb systems are of fundamental importance and have attracted much attention in many areas nowadays. Their reduced symmetry gives rise to interesting collective behavio…
A sharp interface Lagrangian-Eulerian method for flexible-body fluid-structure interaction
Ebrahim M. Kolahdouz, David R. Wells, Simone Rossi +3
This paper introduces a sharp-interface approach to simulating fluid-structure interaction involving flexible bodies described by general nonlinear material models and across a bro…
A fast Chebyshev method for the Bingham closure with application to active nematic suspensions
Scott Weady, Michael J. Shelley, David B. Stein
Continuum kinetic theories provide an important tool for the analysis and simulation of particle suspensions. When those particles are anisotropic, the addition of a particle orien…
Solving Fredholm second-kind integral equations with singular right-hand sides on non-smooth boundaries
Johan Helsing, Shidong Jiang
A numerical scheme is presented for the solution of Fredholm second-kind boundary integral equations with right-hand sides that are singular at a finite set of boundary points. The…
Kernel Aggregated Fast Multipole Method: Efficient summation of Laplace and Stokes kernel functions
Wen Yan, Robert Blackwell
Many different simulation methods for Stokes flow problems involve a common computationally intense task -- the summation of a kernel function over pairs of points. One po…
