How does Watergems CONNECT Edition handle multiple demand adjustments (via Calculator Options) applied to the same element?

If you have multiple demand adjustments accomplished via the simulation calculator that cover the same elements, in what order / priority are the multipliers applied?
The specific case is presented: using an Entire Network multiplier to adjust the system to a given demand, and then tweaking individual areas by using additional selection set based adjustments. 

  • Hello Jeremy,

    After testing, the program will apply all of these to a node. For instance, if a junction with a demand is in both "Entire Network" and "District H", the program will apply a multiplier of 0.35 to the demand (multiplier = 0.7*0.5). Given this, you will want to make sure the appropriate values are included for the multipliers to make sure that the right demand is generated at the end of it.

  • Thanks Scott - appreciate your help.
  • Hello Jeremy,

    The demand adjustments in the calculation options are applied first, in the order they are displayed. The order can be edited with the arrow icons.

    After the demand adjustments from calculation options have been applied, then the demand pattern multiplier is applied.

    For Example:

    Scenario 1:


    Row 1: 100*1.5=150
    Row 2: 150*.8=120
    Row 3: 120+10=130
    Pattern Multiplier: 130*2=260

     Scenario 2:

    Row 1: 100*1.5=150
    Row 2: 150+10=160
    Row 3: 160*0.8=128
    Pattern Multiplier: 128*2=256

    Scenario 3:

    Row 1: 100+10=110
    Row 2: 110*1.5=165
    Row 3: 165*0.8=132
    Pattern Multiplier: 132*2=264
