Flow simulation negative pressure warning
WebDec 12, 2024 · Use a total pressure boundary condition for the inlet (23 PSI), and outlet volume flow at the outlet (20 ft^3/s). This gave me a negative pressure warning while … WebSimulation Options. The Simulation Options dialog box is used to adjust some facets of a model prior to running it. Simulation options are usually associated with specific scenarios. For example, suppose you would like to specify a global bulk chlorine decay of -0.5 for one simulation and have another simulation with a decay of -0.7.
