Title: Mesoscale Modeling Using Particle-based Methods
Abstract: Recent applications in micro-/nano-technology, material assembly and biological systems demand robust and accurate computational modeling of multiphysical processes at the mesoscale. In this talk, I will focus on mathematical models and numerical schemes that can effectively capture mesoscopic multiphysics using particle-based methods. I will discuss both
top-down and bottom-up approaches. In the top-down approach, the stochastic PDEs with consistent thermal scaling were solved to describe the important effects of thermal fluctuation in mesoscale. In the bottom-up approach, coarse-grained molecular models were developed for modeling complex fluids and soft matters in mesoscale such as concentrate suspensions of colloids, red blood cells, etc.
