Capsule refers to a particle consisting of a liquid droplet enclosed by a thin-membrane. Analyzing the behavior of capsules in flow is needed to predict the transport and breakup of the capsules, and to understand the rheological property of the capsule suspension. We have developed a graphics processing unit (GPU) accelerated boundary element method (BEM) for the fluid-structure interaction analysis of capsule suspensions at the Stokes flow regime, where BEM for fluid mechanics is coupled with the finite element method (FEM) for membrane mechanics. Here, we provide an overview of the GPU-accelerated BEM and its application to the rheological analysis of capsules suspensions.
