Discharge Element Bentley Modeling Reference Modeling Reference How are demands treated during the transient simulation in HAMMER?WEBQ - Discharge (cfs, cms) C - A 'discharge coefficient' (distinct from CV used elsewhere in HAMMER) A - The cross-sectional area of the opening (sq. ft, sq. m) g - gravitational acceleration P - Pressure head (ft, m) The C coefficient is calculated using the initial flow and pressure head from the initial conditions calculation.Bentley - Product DocumentationFlow Control Vale (FCV) Attributes - Bentley SystemsWEBDischarge Coefficient (Transient): Discharge coefficient, Cv, is defined as: Flow / (Pressure Drop) ^ 0.5. Operating Rule: Specifies the operation of the valve during a transient simulation.

I am trying to model a pipe burst scenario in the vertical portion of the pipe. I am not sure how to model a pipe burst in Hammer. I tried a discharge to atmosphere, but it doesn't seem correct, when looking at the results. Any advice would be appreciated.
