Radiation Transport Model - A model which can be used to model the transport of photons in physical media along any user specified number of discrete propagation vectors or solid angle domains including interaction with any number of user specified boundary reflections and transmissions and interaction with non-equilibrium molecular dynamics via user specified photo-kinetic mechanisms (e.g. spontaneous emission, absorption, stimulated emission, etc...).
Electric Field Model - A model which can be used to solve for the electric field in arbitrary geometries given boundary applied electric potentials, dielectric regions, and dynamic volume charges (when coupled to the molecular transport model).
Material Properties Model - A model which can be used to apply user specified material property fits (e.g. constant, linear, polynomial, discrete data, functional equations, etc.) to any desired calculation property (e.g. viscosity, dielectric constant, heat-capacity, etc...) as a function of time, position, or other calculation properties (e.g. temperature, pressure, specie concentration, etc...).
