HFSS 3维曲线导入

简介

如图一所示，CST中可以通过导入和到出由任意点组成的曲线，但是HFSS中貌似不能导入（如图二所示），如果我们要将matlab的产生的曲线的点的数据导入特变麻烦，特别是在点特别多的情况。这时可以可以使用脚本导入海量个点所组成的曲线。

环境

python 3.11.5
Ansys Electronics Desktop 2022 R1
vscode

参考

【1】MATLAB-HFSS-API入门教程-第1讲参考了HFSS的脚本使用的基本的介绍

代码

脚本代码由【1】的灵感在HFSS录制出的脚本基础上修改得来。

使用

保存点数文件的格式为坐标由逗号隔开。

将上述修改对应的路径和点数后保存为.py文件，注意保存格式为ascii（win11的记事本不行），或在vscode保存为windows1252格式，只有这样才能正常使用。

在HFSS中运行脚本，Tools=》Run script=》选择刚刚保存的.py文件。

结果

这样就导入了10000个点到HFSS中。
