A performance portable fast Ewald summation for Stokes flow
Gabriel Kosmacher, Ziyu Du, Joar Bagge +1
We present GPU algorithms for Ewald summation methods for accelerating N-body Stokes flow problems in periodic domains. Like most N-body codes, Ewald sums use a near-field/far-fiel…
A stable and fast method for solving multibody scattering problems via the method of fundamental solutions
Yunhui Cai, Joar Bagge, Per-Gunnar Martinsson
The paper describes a numerical method for solving acoustic multibody scattering problems in two and three dimensions. The idea is to compute a highly accurate approximation to the…
Fast Ewald summation for Stokes flow with arbitrary periodicity
Joar Bagge, Anna-Karin Tornberg
A fast and spectrally accurate Ewald summation method for the evaluation of stokeslet, stresslet and rotlet potentials of three-dimensional Stokes flow is presented. This work exte…
Parabolic velocity profile causes drift of inertial prolate spheroids -- but gravity is stronger
Joar Bagge, Tomas Rosén, Fredrik Lundell +1
Motion of elongated particles in shear is studied. In applications where particles are much heavier than the carrying fluid, e.g. aerosols, the influence of particle inertia domina…
Highly accurate special quadrature methods for Stokesian particle suspensions in confined geometries
Joar Bagge, Anna-Karin Tornberg
Boundary integral methods are highly suited for problems with complicated geometries, but require special quadrature methods to accurately compute the singular and nearly singular…
Fast Ewald summation for electrostatic potentials with arbitrary periodicity
Davood Saffar Shamshirgar, Joar Bagge, Anna-Karin Tornberg
A unified treatment for fast and spectrally accurate evaluation of electrostatic potentials subject to periodic boundary conditions in any or none of the three spatial dimensions i…
