PLOT3D is an interactive graphics program for visualizing results
from Computational Fluid Dynamics (CFD) simulations of fluid flow.
PLOT3D reads a (single or multiple block) structured grid file and
an associated flow solution ("Q") file. Plots can be made of any
collection of grid surfaces as well as contour, vector or particle
trace plot through specified subsets of the grid(s).
Functions which can be plotted are divided into five groups:
- GRID FUNCTIONS for walls (geometry), grids, outlines of
blanked-out regions, and grid-check diagnostics;
- SCALAR FUNCTIONS for contour or carpet plots of density,
pressure, temperature, Mach number, vorticity magnitude, helicity,
etc.;
- VECTOR FUNCTIONS for vector plots of velocity, vorticity,
momentum and density gradient;
- PARTICLE TRACE FUNCTIONS for tracing streamlines of vortex
lines; and
- SHOCK FUNCTIONS for finding and plotting shock locations.
PLOT3D is available for a variety of workstation and supercomputer
platforms, including
- Silicon Graphics IRIS workstation (some problems with IRIX 6.2)
- DEC/VMS with DISSPLA graphics software
- Generic Unix workstation with DISSPLA graphics software
- Apollo/Unix with GMR3D graphics (admittedly old)
- Generic Unix supercomputer with SGI workstation
(DISSPLA
is a commercial graphics library from
Computer Associates.)
In addition, third-party software may be available to run the
SGI version (which uses IRIS-GL) on other platforms. See the "Technical Details" page for more information.
Versions of PLOT3D have been released under a number of NASA case numbers, including ARC-12779, ARC-12782, ARC-12783, ARC-12784, and ARC-12789. It was originally released as part of the NASA COSMIC collection.
