LARED-Integration code for numerical simulation of the whole process of the indirect-drive laser inertial confinement fusion

This paper introduces the radiation-hydrodynamic code LARED-Integration, including its physical background, model equations, numerical algorithms and numerical results. The code is developed by Institute of Applied Physics and Computational Mathematics (IAPCM) and mainly implemented to simulate the whole process of the indirect-drive laser inertial confinement fusion (ICF). The code can also be used to study the direct-drive laser fusion process and the radiation-drive capsule implosion process. Compared with the experimental data and the numerical results of the 1D radiation-hydrodynamic code, the reliability of the LARED-Integration code is validated. The numerical simulation of the NIF ignition target is realized by the LARED-Integration code and this code is widely used in the physical research of ICF now.
