<>HFSS学习笔记（四）利用MATLAB脚本进行HFSS快速建模
在HFSS中，我们经常会遇到复杂且重复的模型，比如你要画30个不同的矩形块，每个矩形块都有自己的参数比如，a1,a2,…,a30
,那么此时你就要重复建立30个模型，这样的话，耗费时间且效率低，因此，使用HFSS的脚本功能，利用代码的循环功能，来实现快速建模。
<>一、HFSS脚本录制
1.打开HFSS，点击上方Tools-＞Record Script to File，HFSS开始记录你的操作，并将你的操作转换为代码（有点类似录像的意思）
保存成vbs格式（将你的操作记录保存成相应的文件）
2.建立了一个长为ax11，宽为w的长条
3.停止记录
4.用打开记事本的方式打开你保存的vbs文件，查看代码
Dim oAnsoftApp Dim oDesktop Dim oProject Dim oDesign Dim oEditor Dim oModule
Set oAnsoftApp= CreateObject("Ansoft.ElectronicsDesktop") Set oDesktop =
oAnsoftApp.GetAppDesktop() oDesktop.RestoreWindow Set oProject = oDesktop.
SetActiveProject("cucao_unit_impedace_ay=7_number=5") Set oDesign = oProject.
SetActiveDesign("13_jiaoben") Set oEditor = oDesign.SetActiveEditor("3D Modeler"
) oEditor.CreateRectangle Array("NAME:RectangleParameters", "IsCovered:=", true,
"XStart:=", _ "-ax11/2", "YStart:=", "-w/2", "ZStart:=", "h", "Width:=", "ax11",
"Height:=", _ "w", "WhichAxis:=", "Z"), Array("NAME:Attributes", "Name:=",
"Rectangle9", "Flags:=", _ "", "Color:=", "(143 175 143)", "Transparency:=", 0,
"PartCoordinateSystem:=", _ "Global", "UDMId:=", "", "MaterialValue:=", "" & Chr
(34) & "vacuum" & Chr(34) & "", "SurfaceMaterialValue:=", _ "" & Chr(34) & "" &
Chr(34) & "", "SolveInside:=", true, "IsMaterialEditable:=", _ true,
"UseMaterialAppearance:=", false, "IsLightweight:=", false)
5.以上操作相当于有了一个模板，依据以上模板可以修改各种值。
<>二、MATLAB复现
1.首先用matlab复现以上功能-即建立一个长为ax11，宽为w的长条。
该段matlab代码主要功能是：
（1）创建一个txt文件
（2）用fprintf()功能将vbs文件中的代码打印到目标txt文件中
clc;clear;close all; fid = fopen('ax-model3.txt', 'wt');%会在当前文件夹下生成ax-model3.
txt文件fprintf(fid, 'Dim oAnsoftApp\n'); fprintf(fid, 'Dim oDesktop\n'); fprintf(
fid, 'Dim oProject\n'); fprintf(fid, 'Dim oDesign\n'); fprintf(fid, 'Dim
oEditor\n'); fprintf(fid, 'Dim oModule\n'); fprintf(fid,'Set oAnsoftApp =
CreateObject("Ansoft.ElectronicsDesktop")\n') fprintf(fid,'Set oDesktop =
oAnsoftApp.GetAppDesktop()\n') fprintf(fid,'oDesktop.RestoreWindow\n') fprintf(
fid,'Set oProject = oDesktop.SetActiveProject(
"cucao_unit_impedace_ay=7_number=5")\n') fprintf(fid,'Set oDesign = oProject.
SetActiveDesign("13_jiaoben")\n') fprintf(fid,'Set oEditor = oDesign.
SetActiveEditor("3D Modeler")\n') fprintf(fid,'oEditor.CreateRectangle Array(
"NAME:RectangleParameters", "IsCovered:=", true, "XStart:=", _\n') fprintf(fid,'
"-ax11/2", "YStart:=", "-w/2", "ZStart:=", "h", "Width:=", "ax11", "Height:=",
_\n') fprintf(fid,' "w", "WhichAxis:=", "Z"), Array("NAME:Attributes", "Name:=",
"Rectangle9", "Flags:=", _\n') fprintf(fid,' "", "Color:=", "(143 175 143)",
"Transparency:=", 0, "PartCoordinateSystem:=", _\n') fprintf(fid,' "Global",
"UDMId:=", "", "MaterialValue:=", "" & Chr(34) & "vacuum" & Chr(34) & "",
"SurfaceMaterialValue:=", _\n') fprintf(fid,' "" & Chr(34) & "" & Chr(34) & "",
"SolveInside:=", true, "IsMaterialEditable:=", _\n') fprintf(fid,' true,
"UseMaterialAppearance:=", false, "IsLightweight:=", false)\n') fclose(fid);
2.将生成的ax-model3.txt文件修改为ax-model3.vbs文件，修改很简单，直接重命名，将后缀.txt改成.vbs即可
3.打开HFSS，运行我们生成的ax-model3.vbs脚本
4.生成相应的长条
<>三、MATLAB实现循环建模
1.首先，因为每个长条尺寸不同，我们要先建立好每个长条对应的变量ax，这一步也可以用脚本来去建立
2.然后就是循环建模，代码如下
clc;clear;close all; fid = fopen('ax-model4.txt', 'wt');%会在当前文件夹下生成ax-model4.
txt文件fprintf(fid, 'Dim oAnsoftApp\n'); fprintf(fid, 'Dim oDesktop\n'); fprintf(
fid, 'Dim oProject\n'); fprintf(fid, 'Dim oDesign\n'); fprintf(fid, 'Dim
oEditor\n'); fprintf(fid, 'Dim oModule\n'); fprintf(fid,'Set oAnsoftApp =
CreateObject("Ansoft.ElectronicsDesktop")\n') fprintf(fid,'Set oDesktop =
oAnsoftApp.GetAppDesktop()\n') fprintf(fid,'oDesktop.RestoreWindow\n') fprintf(
fid,'Set oProject = oDesktop.SetActiveProject(
"cucao_unit_impedace_ay=7_number=5")\n') fprintf(fid,'Set oDesign = oProject.
SetActiveDesign("13_jiaoben")\n') str = ["ax11" "ax12" "ax13" "ax14" "ax15"
"ax21" "ax22" "ax23" "ax24" "ax25" "ax31" "ax32" "ax33" "ax34" "ax35" "ax41"
"ax42" "ax43" "ax44" "ax45" "ax51" "ax52" "ax53" "ax54" "ax55"] %先要建立所有变量 for ax
= ["ax11" "ax12" "ax13" "ax14" "ax15" "ax21" "ax22" "ax23" "ax24" "ax25" "ax31"
"ax32" "ax33" "ax34" "ax35" "ax41" "ax42" "ax43" "ax44" "ax45" "ax51" "ax52"
"ax53" "ax54" "ax55"] fprintf(fid,'oDesign.ChangeProperty Array("NAME:AllTabs",
Array("NAME:LocalVariableTab", Array("NAME:PropServers", _\n') fprintf(fid,'
"LocalVariables"), Array("NAME:NewProps", Array("NAME:%s", "PropType:=",
"VariableProp", "UserDef:=", _\n',ax) fprintf(fid,' true, "Value:=",
"8mm"))))\n') end %开始3D建模 fprintf(fid,'Set oEditor = oDesign.SetActiveEditor(
"3D Modeler")\n') for ax = ["ax11" "ax12" "ax13" "ax14" "ax15" "ax21" "ax22"
"ax23" "ax24" "ax25" "ax31" "ax32" "ax33" "ax34" "ax35" "ax41" "ax42" "ax43"
"ax44" "ax45" "ax51" "ax52" "ax53" "ax54" "ax55"] fprintf(fid,'oEditor.
CreateRectangleArray("NAME:RectangleParameters", "IsCovered:=", true, "XStart:="
, _\n') fprintf(fid,' "-%s/2", "YStart:=", "-w/2", "ZStart:=", "h", "Width:=",
"%s", "Height:=", _\n',ax,ax) fprintf(fid,' "w", "WhichAxis:=", "Z"), Array(
"NAME:Attributes", "Name:=", "%s", "Flags:=", _\n',ax) fprintf(fid,' "",
"Color:=", "(143 175 143)", "Transparency:=", 0, "PartCoordinateSystem:=", _\n')
fprintf(fid,' "Global", "UDMId:=", "", "MaterialValue:=", "" & Chr(34) &
"vacuum" & Chr(34) & "", "SurfaceMaterialValue:=", _\n') fprintf(fid,' "" & Chr(
34) & "" & Chr(34) & "", "SolveInside:=", true, "IsMaterialEditable:=", _\n')
fprintf(fid,' true, "UseMaterialAppearance:=", false, "IsLightweight:=", false)
\n') end fclose(fid);
3.将生成的txt文件修改为vbs文件，然后在hfss中运行
4.建模的效果如下
5.因为在创建变量的时候，每个变量的值都是一样的，所以，可以根据自己的参数在左栏的properties中进行修改
