Physics - Plasma Physics, Astrophysics and Multiscale Fluid Dynamics

Overview

Our goal is to use High Performance Computing (HPC) to understand through simulation and visualization complex phenomena, such as magnetized turbulence in fusion reactors, shock waves triggered by supersonic re-entry vehicles, the dense interior of exploding stars and colliding planets, and the diffuse gas of galaxies and star forming molecular clouds. We will use a great variety of computational tools dealing with a very broad range of physical conditions. We will build a new HPC infrastructure for plasma physics, astrophysics and fluid dynamics applications, putting a strong emphasis on our common methodological, algorithmic, software and visualization needs for the next 10 years.

The science covered by this Community spans several domains. The corresponding grand challenge goals pursued by the groups that constitute this PASC network are diverse and are exposed in the following sections. However, we consider that there is a strong case to regroup and coordinate our efforts in the context of HPC. The computational challenges in our communities are characterized by common features: we are all dealing with nonlinear, unsteady, multiscale problems requiring very high spatiotemporal resolution and simulations involving huge amounts of data. These features guide our common synergetic HPC objectives:

  • Simulations of magnetically confined plasmas
  • Cavitation dynamics
  • Structure formation in the universe (cosmology, galaxy formation and evolution, turbulent discs in astrophysics)
  • Magneto hydrodynamics and neutrino transport in stellar collapse and collisions (core collapse supernova explosions, aftermath of neutron star mergers and the neutrino driven wind, collapsars and its connection to long gamma-ray bursts)
