Ansys Employee不知道你看的是哪里?
你可以用脚本把
Poynting vector
提取出来:
pv=getresult("CD::T","P");
px=pv.Px;
x=pv.x;
y=pv.y;
z=pv.z;
image(x,y,px(:,:,1,5));
这里的监视器垂直Z轴,其中5代表频率第5点。
你可以根据矢量作图做矢量图:

下面的例子是用Matlab,在输出数据为Matlab之前,要先将FDTD网格插值为均匀网格,否则图像会失真:

Subscriber你好,我想请问你这个poynhting vector有没有示例呢?这串代码我实在看不懂,导出的X,y,z分别代表什么呢?

Ansys Employee代码看不懂就需要学习,你可以逐行操作,看看工作空间结果是什么样的。X,y,z分别代表监视器每一点的空间坐标,对应面监视器,其中一个坐标值是常数。
