Adding a Transient Analysis

Right-click Analysis in the Project tree and select Solution Setup > Add Transient, or on the menu bar, select Twin Builder > Solution Setup > Add Transient. The Transient Analysis Setup dialog box appears.

A default name for the analysis appears in the Analysis Setup Name field.
The default name is TR. If you specify additional solution setups, the default name increments by 1 (for example, TR1). 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.

Set the desired values for:
- End Time - Tend – The default value is 40ms.
- Min Time Step - Hmin – The default value is 10us.
- Max Time Step - Hmax – The default value is 1ms.
  Hint
  See Guidelines for the Proper Choice of Time Step for help with these settings.
Select units for each value from the drop-down lists.
Select Use Initial Values to load initial values from a file.
Type the path and file name in the text box, or click for a file Open dialog box to locate and load the file.
Select Enable continue to solve to pause the simulator after the current end time. When you select Continue on the simulator progress bar menu, the Transient Analysis Setup dialog box opens, prompting you to enter a new end time (Tend) with which to continue the simulation. The new end time must be greater in value than the current end time. 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.
Right-click an analysis icon in the Project tree and select Disable or Enable to control the analysis. 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 current option.

The Select Solution Options dialog box also lets you add, edit, clone, and remove solution options.

An icon for the transient analysis setup appears in the Project Manager window under the Analysis icon.
