提出了数值建模代码 INF&RNO（集成流体和粒子模拟代码，发音为“inferno”）。 INF&RNO 是一种高效的二维圆柱代码，用于模拟短激光脉冲与低密度等离子体的相互作用。该代码基于激光器的包络模型，而 PIC 或流体描述可用于等离子体。激光脉冲对等离子体的影响通过时间平均动力动力进行建模。与标准完整 PIC 仿真相比，这些功能和其他功能可实现 2-4 个数量级的加速，同时仍保持物理保真度。该代码已针对分析解决方案和 3D PIC 模拟进行了基准测试，此处介绍了一组验证测试以及性能讨论。
The numerical modeling code INF&RNO (INtegrated Fluid & paRticle simulatioN cOde, pronounced “inferno”) is presented. INF&RNO is an efficient 2D cylindrical code to model the interaction of a short laser pulse with an underdense plasma. The code is based on an envelope model for the laser while either a PIC or a fluid description can be used for the plasma. The effect of the laser pulse on the plasma is modeled with the time‐averaged poderomotive force. These and other features allow for a speedup of 2–4 orders of magnitude compared to standard full PIC simulations while still retaining physical fidelity. The code has been benchmarked against analytical solutions and 3D PIC simulations and here a set of validation tests together with a discussion of the performances are presented.
