Center for Radiative Shock Hydrodynamics

About Crash

The Center for Radiative Shock Hydrodynamics (CRASH) was established in 2008 through a $17 million cooperative agreement from the National Nuclear Security Administration's (NNSA) Office of Advanced Simulation and Computing. With this agreement, CRASH is advancing predictive science in the nationally important area of radiation hydrodynamics (RH) via a unified, multi-prong approach.

The overarching goal of CRASH is to accurately simulate RH and quantify the accuracy with which we can predict a given measured output from a given experiment. The CRASH research team aims for a quantitative assessment of how closely their simulations reflect reality.

To substantially improve the ability to do predictive simulations of high - energy - density and astrophysical flows, Center researchers are:

  • Developing a software framework for RH to serve as a testbed for development, verification and validation of RH modeling elements.
  • Developing a system for hierarchically validating the software framework.
  • Extending an existing experimental effort, centered on radiative shocks, to obtain data and quantify uncertainties in the experiments.
  • Simulating these experiments and quantifying the accuracy of the simulations.
  • Establishing a doctoral program for Predictive Science and Engineering.

CRASH Research Team

The CRASH research team, led by Principal Investigator R. Paul Drake, has a 15-year track record of working together on large-scale multidisciplinary physics simulations and software development. CRASH team members, comprised of researchers from six University of Michigan departments and from two Texas A&M University departments, are experts in:

  • Numerical methods for fluids, plasmas, and radiation transport
  • Uncertainty quantification and propagation
  • High - energy - density physics experiments and theory
  • Applied mathematics
  • Software engineering and computer science
  • Uncertainty quantification
  • Parallelization of radiation transport algorithms
