DATASET NAME: Miranda
DATASET OWNER’S NAME AND CONTACT: Andy Cook (awcook@llnl.gov)
DATASET DIMENSIONALITY: Seven 3D scalar fields
DATASET DIMENSIONS: 384x384x256
x: 384 (fastest varying)
y: 384
z: 256 (slowest varying)
PHYSICAL DESCRIPTION OF THE DATASET:
DOMAIN: x, y, z
VARIABLES:
density
pressure (*)
viscosity (*)
diffusivity (*)
velocityx
velocityy
velocityz
(*) These three variables are unfortunately mislabeled and in fact correspond
to three different fields needed to restart Miranda, each of which is a time
derivative of a certain quantity. For consistency with several publications
in which they have previously been used, these fields appear here with their
(incorrect) legacy names. For further details, please contact Peter Lindstrom
(pl@llnl.gov).
DATA NATURE: IEEE-754 FLOATING POINT
ENDIAN FORMAT (LITTLE, BIG): LITTLE
PRECISION (DOUBLE, SINGLE): DOUBLE
Further description:
The fields correspond to a subdomain of an early time step of a Rayleigh-Taylor
instability direct numerical simulation run on a 3,072^3 uniform grid. The
initial conditions are a slightly perturbed planar interface between two
fluids of relative density 1 and 3. The chosen subset contains the mixing
layer between the two fluids.
The data set is named after LLNL's radiation hydrodynamics simulation code
Miranda that generated it. For details on Miranda, see
