ACMM Mini-Symposium on Multiscale Simulations at the Physics-Chemistry-Biology Interface

24May2017 15:30 - 17:00

Lecture

The guest of honour is ACMM professor Sauro Succi, from the IAC-CNR in Rome, Italy and the Institute for Applied Computation Science at Harvard.

He will deliver an ACMM Lecture titled:
Multiscale Simulations at the Physics-Chemistry-Biology Interface

Abstract

Over the last near three decades, the Lattice Boltzmann (LB) method has gained a prominent role as an efficient computational scheme for the numerical simulation of complex flows across a broad range of scales, from fully-developed turbulence in real-life geometries, to multiphase micro-flows, all the way down to nanofluidics and even quantum-relativistic subnuclear fluids. After a brief introduction to the main ideas behind the LB method, we shall illustrate a few selected multiscale applications to biological problems, such as biopolymer translocation across cell membranes, protein folding-aggregation and granular hemodynamics. Finally, we shall comment on the prospects of extreme simulations of biological organelles on future exascale computing platforms using the Lattice-Boltzmann-Molecular-Dynamics code MUPHY.

This lecture will be preceded by a presentation by Dr. Christopher Lowe ( HIMS, UvA) on 

Detecting Networks

Abstract

Does a system possess a network spanning the entire system? This is the classic question addressed in percolation theory. If one considers a finite system with external boundaries it is a relatively simple question to answer. However, in simulations an external boundary has an artificially large surface compared to the bulk, so we usually prefer to use periodic boundary conditions. The question then becomes, do
we have a network that spans the entire periodic network? Answering this question, I will show, is a bit more tricky. We have devised a method that can do so, and I will illustrate its usefulness particularly regarding simulating polymer gels near to the gel point.
