Development and benchmarking of radiation transport models in LSP.

POSTER

Abstract

LSP is a hybrid particle-in-cell (PIC) code widely used to model various plasmas. We report on the recently added improvements to the modeling of radiation and atomic physics within LSP. Multi-group radiation diffusion in 2D Cartesian and cylindrical geometries has been implemented and tested. Also, the ability to utilize detailed opacity and equation-of state tables has been added. We will provide details of the implementation, as well the results of various benchmarks against analytic solutions to the radiation transport problems in multi-dimensions and against one-dimensional hydrodynamics simulations.
