We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

您好,这里有一个问题就是 2D 仿真里面最后的电流是使用的 2D 浓度分布乘以这个 norm length 的结果,可以理解成是这个 2D 结果平移增厚的结果。但是 3D 仿真是直接在 3D 做网格划分计算,因此两个结果有差异是合理的,如果想要尝试减小这个差异,首先要确保模型在第三个维度是均匀的,其次需要网格划分足够精细,即收敛性测试。

另外提醒一下中文贴请发到对应中文分区:/forum/forums/forum/discuss-simulation/photonics-chinese/
