摘要:

我们描述了一个新的框架耦合一个完整的PIC算法与减少PIC算法已实施到代码OSIRIS。我们表明,OSIRIS与这种新的混合PIC算法可以有效地和准确地模拟高能量密度的情况下,如离子加速激光固体相互作用和快速点火的聚变目标。我们第一次在完全自洽的混合PIC模拟中模拟了快速点火目标的全密度范围,说明了以相对较高的效率在核心区域停止激光产生的电子通量的可能性。计算加速超过1000倍的演示,开辟了道路,全尺寸的高能量密度的情况下,多维建模和指导未来的实验。

英文摘要:

We describe how a new framework for coupling a full-PIC algorithm with a reduced PIC algorithm has been implemented into the code OSIRIS. We show that OSIRIS with this new hybrid-PIC algorithm can efficiently and accurately model high energy density scenarios such as ion acceleration in laser-solid interactions and fast ignition of fusion targets. We model for the first time the full density range of a fast ignition target in a fully self-consistent hybrid-PIC simulation, illustrating the possibility of stopping the laser generated electron flux at the core region with relatively high efficiencies. Computational speedups greater than 1000 times are demonstrated, opening the way for full-scale multi-dimensional modeling of high energy density scenarios and for the guiding of future experiments.
