When computing a model in HAMMER which contains discharge to atmosphere elements the following user notification is returned."Invalid results. Please check the input data for the connected elements."
If the discharge to atmosphere element property "Discharge Rating Type" is set to "Rating Curve" then make sure the Pressure Head vs. Flow data contains a sufficient range of values.For example, the image below shows an additional point that was inserted into the table, which ensured that the range would not be exceeded during the simulation.
