## 15.1. Using the User Interface

The following topics will be discussed:

- Domain: Initialization Tab

- Global Settings and Fluid Settings Tabs

The Global Settings and Fluid Settings tabs for the global initialization object (listed as `Initialization` under `Simulation` in the tree view) contain settings that specify how initial values are to be determined, and, in some cases, the initial values themselves. They are accessible by clicking Global Initialization , by selecting Insert > Global Initialization, or by editing the initialization object listed in the tree view under `Simulation`.
