Simple calculation problem? ?

The DSTWU module uses the Winn-Underwood-Gilliland shortcut method for the design of distillation columns. 1: Where is Winn-Underwood-Gilliland chosen? 2: Where is Rmin set? :L hopes experts can tell me!
Beginner’s attempt: 1: Winn-Underwood-Gilliland is its default calculation method; it cannot be selected. 2: Rmin is the result of the calculation :)
The DSTWU module uses the Winn-Underwood-Gilliland shortcut method for the design of distillation columns; it calculates the minimum reflux ratio and the minimum number of theoretical plates based on the given feed conditions and separation requirements, or it determines the number of theoretical plates and the location of the feed tray for a specified reflux ratio.
Winn-Underwood-Gilliland is the calculation method for DSTWU. Its purpose is to (1) calculate the reflux ratio corresponding to a given number of theoretical plates, and (2) calculate the number of theoretical plates required for a given reflux ratio. In either case, the value of Rmin that is calculated remains constant; it depends only on the recovery rate desired for the light and heavy components
