Nov 23-25, 2014: APS 2014 (Nov 24: Talk by Prof. Koumoutsakos)


Prof. Koumoutsakos will give a talk at the 67th Annual Meeting of the APS Division of Fluid Dynamics within session L9 (Frontiers of Computational Science in Transport Phenomena):


Petascale Flow Simulations Using Particles and Grids

Monday, November 24, 2014, 3:35 PM–4:01 PM, Room: 3014/3016

How to chose the discretization of flow models in order to harness the power of available computer architectures? Our group explores this question for particle (vortex methods, molecular and dissipative particle dynamics) and grid based (finite difference, finite volume) discretisations for flow simulations across scales. I will discuss methodologies to transition between these methods and their implementation in massively parallel computer architectures. I will present simulations ranging from flows of cells in microfluidic channels to cloud cavitation collapse at 14.5 PFLOP/s.
