After setting up a trace, age or constituent analysis, There are no results for calculated trace, age or constituent results.
1) Confirm that the Calculation Type in the calculation options is set appropriately. If it's set to "hydraulic only", water quality results will not be computed.
2) Make sure the model is successfully computing. If you see red messages in the User Notification window after computing the model, there may be issues preventing the model from computing, which will need to be addressed first.
3) When viewing the water quality results, ensure that you're either looking at the maximum or minimum, or a graph. If you're only looking at the "Trace (Calculated)", "Age (Calculated)" or "Concentration (Calculated)" field for an element directly after computing a model, that will be showing you the result at time zero.
Either use the Time Browser and step through time to see the calculated result change, or right click the element(s), choose Graph and select the water quality result in question.
4) Ensure that the respective alternative has been set up correctly, or for Age, make sure there is a source of fresh water.
For an age analysis, the calculated age represents how long the water at that element has been in the system. In a model where there is no source of "fresh" water (a reservoir), the age of the water on all nodes will be the same. However, by adding a reservoir to the system, age will start to vary on different nodes.
Note: if you need to analyze multiple trace sources or multiple constituents, use the Water Quality Batch Run feature.
How can I troubleshoot my model when my water age results don't appear correct?
Water age results in a pipe are different than the age in a downstream junction
Age (Calculated) vs. Age (Minimum) vs. Age (Maximum)
Is WaterGEMS capable of modeling the formation of constituents in networks?
The concentration at the stop node directly after a constituent source in a tank is decreasing rapidly
