PEGASUS 5 Examples

NACA 0012 Airfoil: A simple two-dimensional c-grid embedded in two box grids. 3 zones and 74K grid points.
Sphere: A simple three-dimensional spherical grid embedded in a box grid. 2 Zones and 48K grid points.
Wing-Body: A three-dimensional wing and fuselage. 7 zones and 2.62 million grid points.
Business Jet: A Generic Business Jet, including wing, fuselage, and engine. 13 zones and 3.52 million grid points.
Internal flow example: A duct with a sphere embedded inside. 2 zones and 106K grid points.

For each example case, you can download a gzipped .tar file which contains the example. Each example includes a PEGASUS 5 input file, sample output (log) files, input grid files, and an overflow input file. The contents will look something like this:

peg.i
sample.log
sample.mpi.log
overflow/overflow.inp
X_DIR/name1.x
X_DIR/name2.x
.....
X_DIR/namen.x

where name* is the descriptive name of each zone, and match the names used in the peg.i input file. The input grid files are stored as required for input into PEGASUS 5, in individual files (one zone per file) in the X_DIR subdirectory. The grid files are stored as FORTRAN unformatted data files. Therefore, you must choose the gzipped .tar file for your specific platform. Each example case has files for these platforms:

sgi_sp: Silicon Graphics single-precision (real*4)
sgi_dp: Silicon Graphics double-precision (real*8)
linux_sp: LINUX single-precision (real*4)
linux_dp: LINUX double-precision (real*8)
cray: Cray J90/C90
fmt: formatted grid files (must be converted before use by PEGASUS)

WARNING: Single-Precision: The bjet and the wb cases have fine enough grids such that if they are run with single-precision (32-bit) accuracy, the results will differ significantly from a double-precision (64-bit) run. All of the example output files provided here were from double-precision runs.
