Physics colloquium is Feb. 16


A physics colloquium will be held at 4 p.m. Friday, Feb. 16, in 211 Witmer Hall. Subhranil De (Physics) will address "inMultiscale Modeling of Polymer Rheology."

A novel simulation method is proposed which can be used to readily parallelize flow simulations on systems with a large spatial extent. Within the proposed scheme, small parts of the system are simulated with independent non-equilibrium molecular dynamics (NEMD) simulations, where only occasionally information is passed between these parts through an equation-free continuum approach. The power of this method is illustrated in the case of a polymer melt undergoing rapid one-dimensional shear flow. Since it is shown that this flow problem cannot be modeled by using a steady-state constitutive equation, this method offers the unique capability for accessing the non-linear viscoelasticity of complex fluids.

Coffee and cookies will be served at 3:30 p.m. in 215 Witmer Hall.
