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…

A scalable computational platform for particulate Stokes suspensions
Wen Yan, Eduardo Corona, Dhairya Malhotra +2
We describe a computational framework for simulating suspensions of rigid particles in Newtonian Stokes flow. One central building block is a collision-resolution algorithm that ov…

Computing collision stress in assemblies of active spherocylinders: applications of a fast and generic geometric method
Wen Yan, Huan Zhang, Michael J. Shelley
In this work, we provide a solution to the problem of computing collision stress in particle-tracking simulations. First, a formulation for the collision stress between particles i…
