Parallel numerical algorithms for simulations of complex fluids

George Biros, The University of Texas at Austin

Complex fluids are challenging to simulate as they are characterized by fluid-structure interaction and the presence of a stationary or evolving microstructure. We will discuss the discretization of integral equation formulations for complex fluids. In particular, we will discuss the challenges and scalability of algorithms for volume integral equations and we will present a new open-source library for such problems. Key algorithmic primitives include tree-data structures (like octrees) and fast summation methods (like the Fast Multipole Method).  We will compare their performance to other state-of-the art codes. Representative applications will include blood flow in microcirculation and flow in porous media.
