  如图，我将已经计算出来的稳定结构在FDTD中设置好，光源为基膜高斯光束，延z轴正向传播，我现在想知道如何设置探测器和脚本，才能得到单个球体粒子所受到的光力。

  计算光力可以参考这个帖子https://optics.ansys.com/hc/en-us/articles/360042214594-Methodology-for-optical-force-calculations

    感谢回复，我现在在用程序里的MST分析组和volumetric分析组来计算光力，有个问题是两个组出来的值相差非常大，我不知道具体是什么原因。

  链接的最下方有介绍这两种方式的区别。直白的讲就是volumetric适合算体积较小或者复杂的情况，但是需要更高的仿真精度（提高网格划分）。

  你设置的高斯光没有直接照到粒子上，偏了很多，你修正一下，把高斯光源的中心与纳米粒子端部重合，位置也要变，保证从一端照明。
