Adding an AC Analysis

Right-click Analysis in the Project tree and select Solution Setup > Add AC, or on the menu bar, select Twin Builder > Solution Setup > Add AC. The AC Analysis Setup dialog box appears.
A default name for the analysis appears in the Analysis Setup Name field.
The default name is AC. If you specify additional solution setups, the default name increments by 1 (for example, AC1). You can change the name by typing in the text field. The name must begin with an alpha character and may contain only alpha, numeric, and underscore characters.
In the Analysis Control panel:

Start Frequency - FStart – The default value is 1Hz.
Stop Frequency - FEnd – The default value is 1kHz.
AC sweep type (linear) – The default, or decadic.
Frequency time step - Fstep – The default value is 10Hz. This field displays when AC sweep type is linear.
Points per decade - Fstep – The default value is 10. This field displays when AC sweep type is decadic.

Select units for each value from the drop-down lists.
Select Enable continue to solve if you want the simulator to pause after the currently set stop frequency. When you select Continue on the simulator progress bar menu, the AC Analysis Setup dialog box opens, prompting you to enter a new stop frequency (FEnd) with which to continue the simulation. The new stop frequency must be greater in value than the current stop frequency. This process repeats until you manually stop the simulator. If you set Simulation Options to save the simulator state and/or the initial conditions, the corresponding .krn and .aws files are also updated.
Select Disable this analysis to exclude this analysis when analyses are run.
You can also right-click an analysis icon in the Project tree and select Disable or Enable. The icon is gray when the analysis is disabled.

To choose solution options other than the default options, click the button to the right of Analysis Options to open the Select Solution Options dialog box where you can choose the desired solution option for this analysis. The button name indicates the currently selected option.)
Use the Select Solution Options dialog box to add, edit, clone, and remove solution options.
Click OK to close the AC Analysis Setup dialog box.
The AC analysis setup appears in the Project Manager pane under the Analysis icon.
