Adding a Parametric Sweep from a File
You can specify the parameters for a parametric sweep in a spreadsheet that uses either a .csv (comma delimited) or .txt (tab delimited) format. You can then import the parametric sweep using the HFSS>Optimetrics>Add Parametric Sweep from File command.
For example, a .txt spreadsheet file could resemble the following:
@a $b $c[in] d[m] $e $f
0.1 mil 2mm 11 21 0.6in 8
0.2mil 3mm 1.3 2.6mm 3 9cm
...
The first row lists the Project and Design Variable names, and when followed by parentheses, the units. The following rows provide the variable values and units. Project or Design variables must be defined before they are accepted from a file. The characters in variable names are not case sensitive. Consecutive separators are treated as one separator.
The header row also takes units in ( ) as well as the conventional [ ].

关于你的例子数据文件可以设置成：
（1）用全局变量的话：
$rin [mm]
4.2
5.0
6.3
6.9
8.2
（2）用局部变量的话：
rin [mm]
4.2
5.0
6.3
6.9
8.2
