When running Extended Period Simulations (EPS), the occurrence of the “Cannot Solve Equations” error currently causes the entire simulation to fail, with no access to results from the timesteps that were successfully solved prior to the error. It ...

It is sometimes necessary to view the average flow through an element. It's a strange ommission that min and max flow fields are available from Results (statistics) group, but average flow is not.

In HAMMER/OpenFlows, relief/surge valves are typically modeled as discharging to atmosphere, or with logic that does not adequately represent “in-line” relief valves (between two pipes) whose actuation depends on the pressure differential between ...

1. User Data Extension – Make all input fields available to create formulas. As it is right now, I cannot use labels of property fields from a manhole (or a TAP) and use it to create a formula for a conduit. It would be great to be able to use tha...

The discrete gas cavity model is used in other transient analysis software and is described in various texts such as Thorley. It captures variable wavespeed phenomenon due to changing air pocket volume. It has been observed that models which exper...

Objective: To develop a software solution that seamlessly integrates OpenFlows with OpenRoads, facilitating the generation of utility profiles (StormWater, WasteWater, WaterSupply, etc.) and ensuring efficient crossings with other pipes and networ...

In our system we have hundreds of physical customer meters that report hourly pressure. I have these in the model as SCADA elements and they are very useful but... the SCADA elements can only be associated with a junction somewhere else, so the el...

Summary: Enable defining a calculation start time based on a time from start (can be > 24 hrs, e.g., T = 82 hrs), instead of a clock time (has to be 00 hrs to 23 hrs) (see attached figure). Model Setup Information: Our model has 7-day (168 hrs)...

Summary: There is an issue with the default hydraulic parameters when setting up a new calculation option, which can lead to erroneous fire flow results. The hydraulic parameter “Use Linear Interpolation for Multipoint Pumps?” should default to "T...

The functionality of rearranging entries individually is not present in: Selection Sets, FlexTables, Profiles, Queries, Scenarios (on the same level), Alternatives (on the same level) and probably a few that I'm missing. For some of these there is...
