This is for steady or unsteady three-dimensional flows. It employs a DSMC architecture that is similar to that in DS2V, but has an older graphical interface and requires the definition of surfaces by external triangulation programs.
This is a program for steady or unsteady plane, cylindrical or spherical flows. It
includes an interactive program for data file generation and the source codes are
included for both programs. This is a “research code” that I am currently using
for the development of molecular models and DSMC procedures. It may include special
routines related to current research and many potential applications have not been
tested. Users must be prepared to work at the code level if problems are encountered.
This is a well established commercial quality visual interactive DSMC program for
steady or unsteady plane or axially symmetric flows. Users need only specify their
problem in the data input windows and all computational parameters, apart from the
total number of available megabytes, are set automatically by the program. Continuing
unsteady flows or the unsteady development of steady flows can be observed through
the integrated graphics and a movie may be produced. The program employs the latest
DSMC procedures and a normal PC copes with near-continuum problems that would otherwise
require a parallel cluster. The program advises on the quality of the results that
it has provided.
DS2V and DS3V are now free programs and, while I no longer attempt to provide support,
obvious problems will be corrected and procedures and models may be updated. The
source code is not available, but parallel versions that also support Linux have
been produced by Dr Martin Rose and are described at www.pi-dsmc.com.
I have commenced writing a new book simply entitled The DSMC Method. A large proportion
of the DSMC procedures in Molecular Gas Dynamics and the Direct Simulation of Gas
Flows (OUP, 1994) have been either modified or superseded. The new book will be
concerned almost entirely with these DSMC procedures and will contain minimal background
material. I intend to publish through CreateSpace, an Amazon company. This will
drastically reduce the cost of the publication and will permit more frequent updates.
