Petascale Flow Simulations using Grids and Particles
|
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.
