Hello,
I'm running into an issue with an EPS simulation that I'm running and can't seem to resolve an issue. I'm running the model for week long time period and will eventually attempt to run constituent analyses with it for an emergency chlorination program. The issue I'm running into is with 1 of the 3 reservoirs in the system, this reservoir has a tendency to crash the model when it needs to be filled. The other reservoirs seems to be running fine. I think with this issue resolved and some refining, the model will be ready to proceed forward (I'm hoping). I've linked the model for help in obtaining assistance.
One complex thing that may be a source of this problem is that there is a joint use reservoir that is shared between this system and an adjacent system. We do not have SCADA data for that system, but we eventually decided upon using a FCV with a pattern based hourly demand that will call of water to and from this reservoir.
There are many controls in this system and am happy to walk someone through them if they can help me. Thank you for any assistance or guidance you're able to provide.
Please call me at 425-951-5466 if calling is better than the forum.

As discussed in this recent thread, the FCV will induce a headloss necessary to balance energy across the model while meeting the desired maximum flow.
If you're looking to inject a specific pattern of flow into the model, another possible approach is to use a negative demand on a junction, with a pattern. as explained in this article from our Wiki: Modeling an inflow (negative demand) in WaterCAD or WaterGEMS
