RE: Pattern (Demand )

RSP
Offline

Dear All,

Again, I strucked  up in performing Age analysis. I considered a demand pattern named as 'DC' without any time duration for it. while validating the following error message i received. if i changed it as fixed demand pattern it works well.

41566 "min 150 mm dia ADD + 10% for Age" "Pattern" "3427" "DC" (N/A) "Not enough points in pattern. At least two unique points are required." Pressure Engine

I need to run age analysis with DC option or any other solution for this?

Thanks,

RSP

    Hello RSP,

    A demand needs to have at least two points in order to be valid. Even if the pattern is basically a multiplier (or a pattern that is the same over a 24 hour simulation), similar to the following, you need at least two points in it.

     Time from Start (hours) Multiplier
    1.000                                 0.800
    24.000                               0.800
     

    If this doesn't help, could you send a screenshot of what the pattern looks like?

    Thank you.
