The Simulation Parameters Library contains preset saved configurations for simulations. You can view existing simulation parameter sets, modify them, and save new definitions that you can then choose for any model.
You can use this library to create your own default settings. Copy an existing simulation parameters entry or create a new on from scratch. Adjust the settings as desired. Then, as described for Batteries in the main Library section of the help, click on "Simulation Parameters" and change the entry in the drop-down menu to the right of the Library list.
The parameters here correspond to those in the Project Set Up.
