Epanet Software(New user) base demand Vs actual demand

Epanet Software(New user) base demand Vs actual demand

Epanet Software(New user) base demand Vs actual demand


I am new to Epanet so might be asking a silly question.

I ran a couple of simulations a few months ago and saved the results in an excel file. In these results, the base demand and the actual demands were equal. However, I tried to run the same model again and now I see that the actual demands are much less than the base semands. So I want to know what is the difference between the base demand and the actual demand? ( I dont think I tampered with the initial settings).

RE: Epanet Software(New user) base demand Vs actual demand

Have you engaged a pattern?
A pattern multiply's the base demand by a factor to simulate the diurnal cycle of demand or other changes over time

Have you added an emitter? emitters are variable demands that depend upon the supply pressure, good for simulating leaks or sprinkler heads.


RE: Epanet Software(New user) base demand Vs actual demand

Hi hydrae,

I did engage a pattern earlier but I removed all the patterns from the nodes and changed the simulation duration to zero (I assume this is how to run a steady state?).

I have not added an emitter as far as i know.

Another question I have is: By standard, should the actual demand be equal to the base demand?

RE: Epanet Software(New user) base demand Vs actual demand

At this point my suggestion is to simplify the model until you can see what is going on

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
