Subscriber老师您好,我用的模式光源TE基模,前面放置了监视器(如图1),看到透射率大于1,提高网格精度还是比1大,所以我改用了port,但是这样看到的模式和source不一样,用source看到的是图2,用port看到的是图3,请问这个是为什么呢?我又该怎么解决呢? -

Subscriber不好意思老师,好像因为我网不好,发了两条的同时图片也没发出来,麻烦您帮我删除了,等我网络好了我再上传请教

Ansys Employee根据你的描述大致回复如下:
大于1的原因很多,首先不要将监视器放在光源灰色区。如果用Port可以避免此问题。

模式是可以选择的,只要Port和模式光源大小位置一样,选择基本模式应该不会有区别。你可以都选Custom,进到FDE界面看看里面的波长是否一样。如果模式不同很可能是计算的波长不同。
