The simplified spherical harmonics (SPn) method has long been shown to produce accurate solutions for radiation transport problems in a wide range of applications, but it was developed without much theoretical rigor. Recently, new theoretical advances have finally addressed major gaps. However, reference implementations based on the new theory do not exist. Tools built on the SPn method fill an important technological gap between less accurate, fast running methods and first-principles approaches that require peta-scale or exa-scale computing resources Additionally, there is evidence that high quality open source radiation transport tools that support research into numerical methods and parallel algorithms, are extremely valuable to the broader community. Consequently, a high quality library for “low-order” transport physics would enable more rapid progress in research applications focused on nuclear energy, fusion energy, plasma physics, thermal radiaiton transport, and more.
Funding: $60K (2022)
Goal: The goal of this project is to produce a production grade, open source library for solving multi-dimensional radiation transport problems with the simplified spherical harmonics method on unstructured grids.
