The Function Sweep (

) study step is a special case of Parametric Sweep study step, where the solver sweeps over functions defined under a 
Switch node defined under 
Global Definitions>Functions (see 
Switch for Functions). After running a function sweep, you can select from the swept functions from a 
Switch list in the 
Data section of plot nodes to, for example, postprocess and visualize the function sweep.
 
    Add information to the table for each column: Switch, 
Cases, and 
Case numbers. Use the 
Move Up (

), 
Move Down (

), 
Add (

), and 
Delete (

) buttons under the table to organize the data. Use the 
Add (

) button to add a list of existing function 
Switch nodes in the 
Switch column. From the list under 
Cases, select 
All to sweep over all function nodes under the switch. For 
User defined, define a list of functions to switch between as positive integers, representing the first function from the top under the 
Switch node as 1, the second function as 2, and so on.
