The development of a sophisticated multi-dimensional non-local thermodynamic equilibrium code for the transfer of radiation through objects where geometry is important will be continued. Such objects (binary stars, novae, supernovae, Be stars, T Tauri stars, etc.) have been extensively observed from both the ground and space and this code will provide an important diagnostic tool of abundances and physical parameters. Towards this end, several activities are planned to further improve and generalize the program: 1) a refinement of the current numerical techniques for greater speed and accuracy; 2) the implementation of the code in a parallel environment (exploring various possible parallelization routes); and 3) applying the code to real astrophysical objects (specifically Be stars, rapidly rotating hot stars, and luminous blue variables) as a method of testing as well as extracting useful scientific results. The training and support for a postdoctoral fellow in modeling radiative transfer is included. This is an area with few students despite its importance throughout astronomy. The final code will be released to the public.
