python是一款适用性极强的编程语言。一直期待HFSS（三维全波电磁场仿真的行业标准）能有python接口。后知后觉的本人才发现原来HFSS16（2015版本）已经不止支持VB脚本，还增加了python支持，当然它用的是Ironpython，基于.NET，和Cpython还是有一定区别，Numpy
和Scipy
这些库的使用上可能还存在问题。正好网上有牛人已经写好了使用指南，我就当下搬运工，希望有更多的人参与来发展hfss的python自动化仿真。

# ----------------------------------------------
# Script Recorded by ANSYS Electronics Desktop Version 2015.0.0

# ----------------------------------------------
import ScriptEnv
ScriptEnv.Initialize("Ansoft.ElectronicsDesktop")
oDesktop.RestoreWindow()
oProject = oDesktop.SetActiveProject("AntennaTemplate2")
oDesign = oProject.SetActiveDesign("HFSSDesign1")
oDesign.ChangeProperty(
[
"NAME:AllTabs",
[
"NAME:HfssTab",
[
"NAME:PropServers",
"AnalysisSetup:Setup8"
],
[
"NAME:ChangedProps",
[
"NAME:Solution Freq",
"MustBeInt:=" , False,
"Value:=" , "800MHz"
]
]
]
])
oDesign.ChangeProperty(
[
"NAME:AllTabs",
[
"NAME:LocalVariableTab",
[
"NAME:PropServers",
"LocalVariables"
],
[
"NAME:ChangedProps",
[
"NAME:N",
"Value:=" , "7"
]
]
]
])
ChangeProperty就分别是将Setup8的工作频率改为800MHz和改变设计变量N为7的全部代码了。
完全自动化（使用命令行）
ansysedt -RunScript my_script.py，或者你不希望在脚本运行结束后HFSS仍然打开着，使用ansysedt -RunScriptAndExit my_script.py命令。 system('"C:\Program Files\AnsysEM\AnsysEM16.0\Win64\ansysedt.exe" -RunScriptAndExit "my_script.py"')
在这里，你需要提供HFSS的完整运行路径，通过右击HFSS图标-属性-目标获取它。
一些实例
下面是一些示例脚本，它们仅与HFSS16兼容。
你可以在图形界面通过Tools运行脚本，也可以使用命令行的形式。
1. 创建一个新的工程
"""Create a new project"""
import ScriptEnv
ScriptEnv.Initialize("Ansoft.ElectronicsDesktop")
oDesktop.RestoreWindow()
oProject = oDesktop.NewProject()2. 打开一个已经存在的工程
"""Open an existing project"""
import ScriptEnv
ScriptEnv.Initialize("Ansoft.ElectronicsDesktop")
oDesktop.RestoreWindow()
oDesktop.OpenProject("C:/Users/pier3595/Desktop/Project1.aedt")3.1. 改变工作频率并扫频
""""Change sweep solution frequency and a sweep frequency"""
# Locate the project file on your desktop
# These three lines are just plain Python, and have *nothing* to do with HFSS.
import os
project_file = os.path.join(os.path.expanduser('~'), 'Desktop')
project_file = os.path.join(project_file, 'AntennaTemplate.aedt')
import ScriptEnv
ScriptEnv.Initialize("Ansoft.ElectronicsDesktop")
oDesktop.RestoreWindow()
oDesktop.OpenProject(project_file)
oProject = oDesktop.SetActiveProject("AntennaTemplate")
oDesign = oProject.SetActiveDesign("HFSSDesign1")
oDesign.ChangeProperty(["NAME:AllTabs", ["NAME:HfssTab", ["NAME:PropServers", "AnalysisSetup:Setup8"],
["NAME:ChangedProps", [ "NAME:Solution Freq", "MustBeInt:=", False, "Value:=", "500MHz"]]]])
oDesign.ChangeProperty([ "NAME:AllTabs", ["NAME:HfssTab", ["NAME:PropServers", "AnalysisSetup:Setup8:Sweep1"],
["NAME:ChangedProps", [ "NAME:Start", "MustBeInt:=", False, "Value:=", "460MHz"]]]])
oDesign.ChangeProperty([ "NAME:AllTabs", [ "NAME:HfssTab", [ "NAME:PropServers", "AnalysisSetup:Setup8:Sweep1" ],
[ "NAME:ChangedProps", [ "NAME: Stop", "MustBeInt:=", False, "Value:=", "540MHz"]]]])
该脚本改变Setup8的工作频率到500MHz，并且改变Sweep1的起始频率为460MHz、截止频率为540MHz。但是它还做了一些事：他利用普通的python函数来找到你的桌面并且打开指定的文件。这使得脚本更加强大。只要你在桌面上有AntennaTemplate.aedt 文件，它就会运行。能够使用python通用函数使得HFSS脚本编程非常强大有用。该脚本使用了python的os模块。
3.2. 改变一个设计属性
""""Change a design property."""
# Locate the project file on your desktop
# These three lines are just plain Python, and have *nothing* to do with HFSS.
import os
project_file = os.path.join(os.path.expanduser('~'), 'Desktop')
project_file = os.path.join(project_file, 'AntennaTemplate.aedt')
import ScriptEnv
ScriptEnv.Initialize("Ansoft.ElectronicsDesktop")
oDesktop.RestoreWindow()
oDesktop.OpenProject(project_file)
oProject = oDesktop.SetActiveProject("AntennaTemplate")
oDesign = oProject.SetActiveDesign("HFSSDesign1")
oDesign.ChangeProperty(["NAME:AllTabs", ["NAME:LocalVariableTab", ["NAME:PropServers", "LocalVariables"],
["NAME:ChangedProps", ["NAME:ws", "Value:=", "2mm"]]]])pip install hfsslib
