Exnihilo is a transport code system that contains both deterministic and stochastic (Monte Carlo) solvers. The deterministic solvers are contained in the Denovo [1] package while the Monte Carlo solvers are imple mented in the Shift package. This document explains the mathematical and numerical methods employed within Exnihilo.
