Ansys Employee这个可能比较棘手。你可以试Custom:
但是对数里面不能出现0。
你也可以考虑将结构做成二值函数: Binary spatial data - Simulation object
也可能还有其它办法,需要先试一下这两个方法。

Ansys Employee第一种方法:最下面的Custom用所需要的材料,而第二个Custom用金材料可以。你可以用Index监视器检查一下。
第二种方法:正常的,你用Index监视器看基本上都是这样,因为FDTD是离散的。2000点应该比网格点多,已经不错了。
GDS也可以。
当然第一种方法看起来更好,更精确些,Conformal技术会更好。

Ansys Employee你需要改Mesh Order。把金属改为3,第一个custom不要选取etch,而应该先空气折射率1,Mesh Order2,第二个custom选取了Au, Mesh Order 1。 再通过折射率监视器看看。参见
Ansys Insight: Lumerical 不用布尔运算如何设置嵌套结构 (mesh order)
GDS你需要在SolideWorks画出这个形状,然后输入,材料Mesh Order 1,折射率1。
