silvaco atlas仿真光谱响应的问题

使用silvaco tcad模拟雪崩光电二极管，结构工艺与网格应该都没有问题，击穿电压也能模拟得到，但是在模拟光谱响应的时候，运行到solve prev b1=2 lambda=0.1这一行就没有反映了，也没有任何提示。贴上atlas一段代码，希望大神指正啊。

有可能是一开始就把光强加到2太大了，试试逐步增加光强看看

rays改小一些看看，比如10

请问Si、poly和SiO2这三种材料的折射率还要输入吗?还是silvaco里面这些信息都有，运算的时候就自己调用了?

应该是不需要输入折射率的

现在有结果了吗?亲，这个是不是要加折射率的呀。

请问各位大神：我刚接触 silvaco有几个问题不怎么懂，我简单的仿真一个3维器件的电阻，为什么我网格的疏密程度不一样，器件的电阻值就不一样，也不一定是越密越好，如何确定一个比较正确的网格大小呢?
而且在调节的时候老是出现Electrode shortened in Z-direction.或x或y
Error: Memory allocation failure.Try killing processes or see system administrator.这是什么问题呢?
谢谢

请问各位大神，为什么我做出来的光谱响应图是折线 不是曲线呢?
