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 2012-06-13 11:32:02 MSK: [DEBUG] Program started 2012-06-13 11:32:02 MSK: [DEBUG] Using problem file: example.prb 2012-06-13 11:32:02 MSK: [DEBUG] Macroscopic data output file: macro.txt 2012-06-13 11:32:02 MSK: [DEBUG] Not writing ensemble data 2012-06-13 11:32:02 MSK: [DEBUG] Using body definition file: ./reentry2.geo 2012-06-13 11:32:02 MSK: [DEBUG] Starting simulation 2012-06-13 11:32:04 MSK: [DEBUG] Not steady yet; particles count: 1662080 2012-06-13 11:32:05 MSK: [DEBUG] Not steady yet; particles count: 1661946 2012-06-13 11:32:06 MSK: [DEBUG] Not steady yet; particles count: 1662026 … * dsmc-caster dsmc-caster is a program used to view bodies defined using `.geo` format. $ 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.
