One of the main research areas of the CRUNCH group is to develop and employ stochastic multiscale computational techniques to diverse problems in complex fluids and soft matter. Currently, we are working on this research area developing different simulation techniques including Dissipative Particle Dynamics (DPD), Smooth DPD (SDPD), and Smoothed Particle Hydrodynamics (SPH) as well as concurrent coupling between these methods. The DPD Club meets weekly in the Division of Applied Mathematics at Brown University in order to provide opportunities for enhanced exchanges and collaborative research among researchers interested in DPD, either inside or outside of the group. Our main sponsors are the Department of Energy (DOE) via the Collaboratory on Mathematics for Mesoscopic Modeling of Materials (CM4) and the National Institute of Health.

If you have done exciting work on DPD or other particle-based methods and you would like to share it with us, just contact Dr Xuejin Li, Xuejin. If you are interested in visiting us, we will cover related travelling and accommodation expenses.
A couple of software projects have been actively developed within the group and available under the GPL license to the general public.
