摘　　要：介绍了辐射流体力学程序LARED集成程序的物理背景、模型方程、数值方法和数值算例。该程序主要应用于激光间接驱动惯性约束聚变的二维整体模拟,兼顾激光直接驱动、辐射驱动靶丸内爆过程和流体不稳定性等物理过程的数值模拟。通过与实验数据、一维辐射流体力学程序进行比对,验证了程序的可靠性。该程序实现了多群输运建模下NIF点火靶的全过程数值模拟,并已应用于惯性约束聚变的物理研究。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 1Dradiation-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.
