Using existing Monte Carlo radiation transport codes, SWORD supplies a vertically integrated framework for creating models, assigning emission spectra, running the MC code and analyzing the results. The user interface is independent of the chosen MC engine.
SWORD gives the user the option of running his simulation using one of two well-known known simulation engines: GEANT 4 from CERN (Version 8.1 included in package distribution) and MCNPX. In general, the SWORD workflow consists of four steps:
- Design the scenario. In this step, all the geometric elements of the simulation are defined, together with material properties, radioactive emission and detector properties. The tool used here is the SWORD geometry builder, a CAD-like graphical tool.
- Configure the run. Here, all the simulation run parameters are defined. This includes simulated duration, which analysis processes will be run, and what outputs will be produced.
- Run the simulation. Normally this is done from within the SWORD interface. However, SWORD can also be run in ?batch? mode without graphical interfaces. The latter is useful for running high compute time runs on high performance machines.
- Examine the results. Spectra and images are output as ASCII text files. SWORD provides interactive viewers for spectra and images. Alternatively, the output files can be read and analyzed using a variety of software tools such as spreadsheet programs.
