Problem

When I create a graph under View > Graphs, or a profile under View > Profiles, this seems to only show the initial conditions (steady state). Where can I view detailed graphical results of the transient simulation?

Solution

The transient results are viewed in the Transient Results Viewer, located under the Analysis menu. The amount of results included in here is determined by the report period, report points and "generate animation data" settings, under Analysis > Calculation Options > Transient calculation option

The Transient Results Viewer displays transient results in graph form and also can animate hydraulic grade in a profile.

In the Profiles tab, you can select a profile (defined in the main user interface under View > Profiles) and then either plot or animate it. The plot will provide the minimum/maximum transient envelope. With a profile animation, you can see how the hydraulic grade profile as it changes over time. This is useful to understand how certain transient inducing events affect the system as a whole. If the animate button is grayed out, make sure to set "Generate Animation Data" to True in the transient calculation options. See this link for details: Using Transient Results Viewer animations for visualizing a transient simulation. To reduce the amount of profiles available, go to View > Profiles, right click on the ones you'd like to omit from the transient results viewer and deselect "Transient Report Path".

The Time Histories tab displays results at the connection point of a pipe and node as a graph. The available points is defined by the "Report Points" option in the transient calculation options. Note that transient simulation results are available at the ends of the pipes where they meet a node element. For example, the upstream side of a pipe or the downstream side of a pump. For time histories, you have options to plot hydraulic grade, pressure, flow, air/vapor volume, and force (if you've chosen to compute transient force). With Time History graphs, you also have the option to view results for multiple scenarios on the same graph, for easy comparison of results. See this link for more details: Viewing HAMMER results for multiple scenarios.
