What does the Extended CAV calculation option do?
Setting the “Run Extended CAV” calculation option to “true” changes the calculation approach for air valves. Sometimes it is more appropriate to use one versus the other. The extended CAV approach is an inelastic approach, so if you have a triple acting air valve with transition volume, it may not be appropriate. (since that is more of an elastic approach.) The extended CAV option is more suited for sufficiently large volume of air entering and the flow regime evolves from hydraulic transients to mass oscillations. Besides improved computational efficiency, the rigid approach allows for the tracing of the air-liquid interface (normally HAMMER only tracks the volume of air, not the location).
