This document is the beginnings of combining the theory of electron production and the code implementations in MCNP and other codes. The hopes of this is to help translate all the theory into the theory manual of MCATK. In addition, this will help the MCATK team to know how other codes treat electron physics.
Slides documenting some of the basics in how MCATK handles the mesh, mesh indexing, materials (IDs and Densities), material indexing, and domain decomposition indexing. These basics hold when using the hybrid parallelism; a full domain decomposition is one replica; a full domain replicated is when number of replicas equals the number of ranks; for the other cases of replicas then the decomposition is what is described here within each replica.
This whitepaper provides details for the background, conventions, definitions, transformation equations, examples, and implementation used in the Solid Body Geometry (SBG) transformations in Monte Carlo Application ToolKit (MCATK).
