Experience with Unstructured-Mesh Electron Transport with Massively ParallelComputing

摘要

The ability to model the transport of electrons through materials is needed forsuch diverse applications as the radiation hardening of electronics, satellite shield design, and medical radiotherapy. Furthermore, it is desirable to faithfully model complex geometries with an arbitrary grid and to perform the computations efficiently on massively parallel computers. Monte Carlo methods have been applied to electron transport problems for some time. However, Monte Carlo is notoriously inefficient for computing differential quantities and for tracking unlikely events.
