Radiation hydrodynamics simulation of high-Z doped ICF targets

Abstract

We conducted a comparative study among the Bi-CG family with incomplete LU factorization employed for solving diffusion-type radiative transfer equation in radiation hydrodynamics (RHD) simulations for laser-produced plasmas. The result suggests that Bi-CGSTAB is the most suitable method thanks to its high convergence stability and low computational cost. RHD simulations were performed for Rayleigh–Taylor instability experiments of an inertial confinement fusion target. We found that higher harmonics of static pressure perturbation become important at an intermediate wavelength.
