Can someone explain to me what the "Time Step Critical Elements" are when running a SewerGEMS Model with the explicit solver? After a model run when looking through the summary report, there is a section titled "Time Step Critical Elements". My model shows one element listed here with a % value next to it. What is the significance of this?
Just to add - specifically regarding the section called "Time-step critical elements" in the SWMM output report - this refers to the element that was controlling the variable time-step during the simulation, when the "Use Variable Time Step?" calculation option is set to "True". You can trad more about this option in the Help documentation and in the article that Sushma mentioned. With a smaller timestep, there will tend to be fewer elements controlling the time step during the simulation.
