HydrauliCAD's
Scenarios "ALL the Way"
|
Example
of a Complex scenario with "Varying Demands.
Tank
Level controls Pump & Valve On & Off" running in 2 separate
scenarios within it.
(With
a "What IF" Pipe Size + Specification change thrown in for the
last Time Step)
Some use term "alternatives" but HydrauliCADs' Scenario engine
structure is far more flexible & encompassing than the more limited
"alternative" structure, allowing the modeler to "Play
What IF" with the epanet math engine to degrees not possible
with any other software that we have examined to date

(line 1) - This Scenario
also is running an independent Scenario to Close a valve based
on Tank Level
+ (line 2) - it is also running an independent Scenario to Turn
a Pump On or Off based based on Tank Level
+ (lines 3&4) - At start of Time Step 3, it sets Demands for selected
Outlet Node(s) to an Absolute value of 250 gpm
+ (lines 5&6) - At start of Time Step 5, it resets the Outlet Node
Demand(s) to it's original value
+ (lines 7&8) - At start of Time Step 10, it multiplies the current
values of the selected Outlet Nodes X 1.55
+ (lines 9&10) - Reset those values back to their original settings.

+ (lines 11&12)
- At start of Time Step12, it multiplies Demands for selected Outlet Node(s)
X 1.1
+ (lines 13&14) - At start of Time Step 15, it sets the selected Outlet
Node Demand(s) to the absolute value of 215 gpm
Similar for (lines 15-18),
Then,
+ (lines 19-21) - At start of Time Step 20, it performs 2 independent
operations a & b:
a - (line 20) - Resets Demand Value for the selected Outlet(s) to the
Original Value X 1.3
b - (line 21) - Sets, for selected pipes, Specification
to "PVC" ASTM-2241 SDR42 and Size to 10"
