Code-to-code comparison and validation of the radiation-hydrodynamics capabilities of the FLASH code using a laboratory astrophysical jet

The potential for laser-produced plasmas to yield fundamental insights into high energy density physics (HEDP) and deliver other useful applications can sometimes be frustrated by uncertainties in modeling the properties behavior of these using radiation-hydrodynamics codes. In an effort overcome this corroborate accuracy HEDP capabilities publicly available FLASH code, we present detailed code-to-code comparisons between HYDRA code developed at Lawrence Livermore National Laboratory previously published simulations from Grava et al. [Phys. Rev. E 78, 016403 (2008)]. That study describes a laser experiment that produced jet-like feature authors compare astrophysical jets. Importantly, (2008)] included x-ray interferometric measurements electron number densities time-integrated measurement soft spectrum. Despite markedly different methods treating computational mesh, equations state opacity models, results resemble and, most importantly, experimental density.
