A specialized table slot used to hold periodic data that repeats at a regular time interval. For example, a set of monthly evaporation coefficients for a reservoir could be entered into a periodic slot. Periodic slots can also contain non-periodic data, as well as text or numeric column headings.

In the game of football, a player in the slot is one who gains only 8-15 yards, and rarely breaks out for a long gain unless they can make a defender miss. A good slot receiver stays close to the line of scrimmage, and focuses on speed and concentration. When playing slots, it is important to minimize distractions by eliminating unnecessary noise and shutting off your cell phone.

When a slot is highlighted, the Slot Viewer displays different menu options depending on the type of slot. You can click or drag a column header to rearrange the Slot Viewer columns. Some types of slots (such as Expression and Series Slots with Periodic Input) have additional configuration settings that can be accessed through the Slot Dialog.

You can configure the Slot Viewer to show warning messages when a value is set during simulation that violates a convergence limit. This is useful for preventing accidental overshooting of a target value. See Setting Convergence Options for more information.
