老师您好,我利用脚本自定义一个椭圆光光源并在z=0处输入,光源visualize的图像是一个椭圆光,但是我用一个监视器观察光源的传输情况,此时没有添加结构,发现在监视器中visualize的电场跟输入的电场不一致,发生了变形,请问老师是什么原因呢?
October 21, 2021 at 2:54 pmGuilin SunAnsys Employee"同样是z=0处"就有问题了: 光源的灰色区域因为抑制后向传播有一到两个的网格使用了非物理的方法,因此里面的场是不正确的,你需要将监视器加在离开光源灰色区域一个网格以上的距离。你再试一下看看。October 22, 2021 at 2:28 pmOctober 22, 2021 at 3:12 pmGuilin SunAnsys Employee传播一定距离会有变化,但是你这个好像是旋转了,不知道你的高斯光束脚本是什么样?不是正椭圆?仅凭结果很难猜测原因啊。October 28, 2021 at 10:44 amOctober 28, 2021 at 12:35 pmGuilin SunAnsys Employee某点的场可能有较大差别,这是因为理论结果是简化的标量结果,实际仿真的是矢量结果,你看看场分量就知道了。也就是说,这种情况所谓的“理论”并不正确而是近似。这种情况再发散角比较大时特别突出。
