DSMC toolkit for rarefied gas dynamics

Latest on Hackage:

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

This package provides CLI to dsmc library to perform rarefied gas flow
simulation. The tool is named `dsmc-runner`. Another tool,
`dsmc-caster` is used to render CSG bodies to check if the body
geometry is defined correctly.

Both programs can be run with `-?` flag to obtain usage informaiton
and help of command-line flags.

To run programs using multiple threads, specify `+RTS -N` flag.

Extra data files which are installed with this package can be found in
`share` directory used by Cabal.

* dsmc-runner

To perform a simulation, input parameters for DSMC must be defined in
«problem file», which uses INI-like format, see `example.prb` included
in the package.

To define the body (which is then referenced from the problem file),
`.geo` format is used, see `body.geo`, `smiley.geo` and `reentry2.geo`
for example.

The runner dumps macroscopic data in text format to the file specified
using `-m` option, which can be then analyzed using visualization
software like ParaView.

To sum up,

$ dsmc-runner example.prb -m macro.txt +RTS -N

* dsmc-caster

dsmc-caster is a program used to view bodies defined using `.geo`

$ dsmc-caster smiley.geo +RTS -N

Drag with left mouse button to rotate the object and mouse wheel to
zoom in/out. More command-line options are available, see usage help
with `-?` flag.
