In Figure 1, the thickness of the surrounding film is a variable. In fact the project is to study the effect of the film thickness on the mode. Therefore this project should have a parameter for the film thickness, and the software may change it to other values during simulation.
To create a suitable parameter, follow these steps.
|1||Go to Solving >> Edit Parameters … to open the Variables and Functions dialog box.|
|2||In the User Variable tab, enter the name of the variable, “EtchedFilmThickness”|
|3||In the Expression field, enter a starting value, 0.4|
|4||Click Add/Apply to add the parameter to the User Variables list|
