A fast mesh-free boundary integral method for two-phase flow with soluble surfactant
Samantha G. Evans, Michael Siegel, Johannes Tausch +1
We present an accurate and efficient boundary integral (BI) method for simulating the deformation of drops and bubbles in Stokes flow with soluble surfactant. Soluble surfactant ad…

A hybrid interpolation ACA accelerated method for parabolic boundary integral operators
Sivaram Ambikasaran, Ritesh Khan, Johannes Tausch +1
We consider piecewise polynomial discontinuous Galerkin discretizations of boundary integral reformulations of the heat equation. The resulting linear systems are dense and block-l…
