Computer Simulations

While a majority of the research to be carried out by the Center will be
experimental, it is not possible to achieve an understanding of the
complex plasma phenomena observed in high energy density plasmas without
the aid of state-of-the-art computer simulation codes. They have become
a key part of the discovery process because of the ability to test
hypotheses by turning off physical effects (such as radiation loss) or
moving from a 2D to a 3D calculation. Therefore, some research
activities will involve the development of numerical simulation models
to aid in the understanding of our experimental data, whether they are
from wire-array z-pinch implosions, single-wire explosion tests,
astrophysical simulation experiments, or are spectra from highly
stripped, high-Z atoms in near-solid-density plasmas. Still other tasks
will be for the purpose of developing a database for benchmarking
computer simulation codes used at the National Laboratories, such as
SNLA’s ALEGRA, and to check equation-of-state and resistivity models
used in those codes.
