RSim: A Simulation Tool Integrating Radiation Codes and CAD.

It is important to NASA engineers to be able to model radiation effects through very complex vehicle structures. This requires a user-friendly cross-platform application capable of the full workflow execution: starting from CAD geometries and materials and setting up radiation environment; proceeding to run simulation in parallel and, finally, analyzing and visualizing simulation results. RSim application developed by Tech-X in Phase II offers such a solution and will be extended to TRL 8 in the proposed development. The main goals are to finish the full support for Geant4 simulations; extend RSim to run in parallel on clusters and supercomputers; add abilities to deal with problematic CAD geometries; and implement geometry conversion methods for the use in the additional Radiation Transport codes. In the course of the proposed development, RSim will to be used by the Space Radiation Analysis Group (SRAG) at Johnson Space Center to import full Spacecraft CAD models to simulate expected dose and particle flux throughout the vehicles and compare to post-mission data. This will result in NASA’s ability to know how well the high-fidelity models allow the mission exposures to be predicted. These particle flux predictions can also be used as input to the radiation risk model that is used to determine which astronauts can perform which missions without exceeding Permissible Exposure Limits. Non-NASA applications are in satellite industry, global radiation detection, monitoring and safety industry, radiation therapy, high-energy and nuclear physics in National laboratories and nuclear plants design and simulations.

This is a mature technology (TRL 8) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
