RSim: A Simulation Tool Integrating Radiation Codes and CAD.

Tech-X will develop a standalone cross-platform application RSim. This application will have a Graphical User Interface (GUI) for performing common radiation transport simulations. Without the need to write code in C++ or Fortran and inputs for models, users of RSim will be able to set up the radiation environment, geometry and materials of the analyzed system, choose the analysis type (tallies), run simulations and perform visualization of the simulation results. RSim will be use two simulation engines: Geant4 and MCNP6. RSim will be integrated with the Computer Aided Design (CAD) by supporting CAD data import and translating it into the format understood by the underlying codes.In addition to providing the traditional geometry support used in these code, we will also implement the DAGMC technology under development at the University of Wisconsin-Madison that would allow us to improve simulations performance.RSim will provide a unique innovative combination of features: (1) validated support for CAD needed for integration with CAD tools, (2) a cross-platform standalone GUI application working with two radiation codes, Geant4 and MCNP6 and (3) unified visualization of setups and simulations outputs.
