RSim 3.0.0 is now available

Tech-X Corporation has released RSim 3.0.0, a cross-platform radiation simulation tool with a user-friendly interface.  Inspired by a collaboration with NASA that required Tech-X to determine the level and effect of radiation on an instrument for the Europa Clipper mission, RSim allows engineers to predict radiation dose and flux in order to develop more effective radiation shielding.  With its comprehensive design and intuitive user interface, engineers can use RSim without needing to learn C++ input commands or secure their own access to radiation codes such as GRAS or Geant4.  In the latest version of RSim, ease of use continues to be emphasized, and RSim 3.0.0 includes multiple enhancements to visualization, modeling, and statistical analysis capabilities.

Improved Statistical Analysis, Histograms, and Probe Diagnostic Capability

The most common RSim application is in designing radiation shielding for delicate equipment and astronauts in unforgiving environments, which requires the development team to continuously look for improvements to accuracy.  In RSim 3.0.0, both source and geometry biasing have been implemented, allowing for a significant reduction of uncertainty in simulation results while minimizing simulation time.  Histograms have been added to provide another option in data analysis.  Finally, the introduction of probe diagnostics gives users the ability to probe radiation environments in different locations and with different materials, providing a more comprehensive picture of the situation being simulated.

Users of RSim 3.0.0 can plot 1D histograms for fluence, flux, and particle spectrum tallies
Increased Options For Simulation Visualization

RSim 3.0.0 simulation runs create a volume of data in areas of energy deposition, radiation flux, and more.  Visual exploration of 3D simulation data can provide additional understanding of simulation results, and visualization features have been greatly enhanced in this version.  RSim 3.0.0 features individual plot controls for clips, opacity, log scale, and number of surfaces.  Combined nodal and zonal imagery allows users to switch from zonal to nodal visualization for mesh tallies.  Lastly, slicing and scale control have been added to the setup interface providing more options during simulation setup.
