If I do an EPS and then decide to annotate the pipes and junctions with respective pressures and nodes, is there a way to identify which time step of the EPS is being displayed? I have a hard time understanding the results on the model itself. My summary is all green and everything is balanced per the results but if I try to get the system annotate everything the numbers are not what I expected. The same question applies for the Flex tables. I'm having trouble understanding what time step is showing up in the flex tables. I'm new to watergems and just need some help interpreting the results.
First, make sure the Auto Refresh option is selected (has a checkmark beside it) in View - Refresh. This Wiki article contains more information.
The results are probably reflecting the first timestep before water begins to flow through the system. See this Wiki article for instructions on how to look at certain time steps.
Also, as a new user, you might find the following article to be a good resource - Learning Resource Guide for new users of Bentley WaterGEMS and WaterCAD.

Thank you for this. It was definitely helpful. I definitely feel like I've gotten further than I was when I sent the message earlier but still having some trouble. If I understand this correctly, demand patterns represent the 'fixed demand' with multipliers for whatever time of day (i.e. 1 GPM with a 1.6 multiplier would be 1.6 GPM) then shouldn't I see that in the results? I understand you don't have my model in front of you but what I'm struggling with is that everytime I go to graph a demand for a junction, the junction graph over a 24 hr period is considerably different than what I expected it to be. My fixed demand is let's say 10 GPM and well it never even gets to 10 GPM? Is it saying my pumps can't handle the demand?
Can you please also include a screenshot showing the Demand Collection for this particular junction, showing the base demand and pattern name?

Thanks for the extra screenshots. I assume the top-left shows the demand collection for the junction in question.
Please check the "Daily Factors" and "Monthly Factors" tabs in the demand pattern to make sure they are not set to 0.1 (the calculated demands you're showing appear to be one tenth of what they should be based on the hourly pattern multipliers).
If this does not help, can you simplify the model down to one pipe for example (reservoir > pipe > junction in question) and remove any other library components, and send a copy of that using the private method mentioned in this article?
If that is not possible, please send me a private message with your company information ("Site ID" found under File > Help > About) so that I can open a Service Request for this and try to schedule a meeting if your company has a SELECT or ELS subscription. I was not able to locate your company based on your Communities account email address.
Thank you!! This fixed it! Apparently my Saturday and Sunday multipliers were set to 0.1. I changed them back to 1.0 and everything appears to be running how it should now. Funny how the smallest things can create such tedious problems. Is there a way to check the internal clock in the program?
I will send you a private message with our Site information. I do believe we have a Select account.
Great. I have added this to the related article: Calculated demand does not match entered demand
