Journal ArticleDOI
Simulating the dynamics and interactions of flexible fibers in Stokes flows
TL;DR: In this paper, the authors employ a nonlocal slender body theory that yields an integral equation along the filament centerline, relating the force exerted on the body to the filament velocity.
Journal ArticleDOI
Numerical approximations of singular source terms in differential equations
TL;DR: In this paper, the authors introduced a new high order multi-dimensional techniques for differential equations and numerical quadrature based on the analysis and numerical results of the singularity regularization.
Journal ArticleDOI
Discretization of Dirac delta functions in level set methods
TL;DR: Two methods for constructing consistent approximations to Dirac delta measures concentrated on piecewise smooth curves or surfaces are presented and are introduced to replace the commonly used but inconsistent regularization technique.
Journal ArticleDOI
A finite element based level-set method for multiphase flow applications
TL;DR: In this article, a numerical method for simulating incompressible two-dimensional multiphase flow is presented based on a level-set formulation discretized by a finite-element technique.
Journal ArticleDOI
Regularization Techniques for Numerical Approximation of PDEs with Singularities
TL;DR: The technique of local regularization for handling problems with singular source terms or discontinuous material coefficients is discussed and new numerical methods are presented and analyzed and numerical examples are given.
