Easily model a wide range of system components and surge devices
Understand the transient response of your system, knowing how valves, pumps and other components will dynamically interact with each other.
Evaluate the effect of pressure surges due to vapor cavity collapse by modeling vapor cavitation and liquid column separation.
Validate the design of safety features to produce safer, more economical pipe systems.
Design and Operate Your System with Greater Safety and Reliability
Avoid potentially catastrophic effects of waterhammer and other undesirable system transients
Prevent transient pressure issues by properly sizing and locating surge equipment, such as surge tanks, gas accumulators, and relief valves
Initiate transients based on time or events in the system
Reduce surge magnitudes by adjusting system component transients such as valve closure time or pump speed
Easily animate and visualize a waterhammer event to improve fundamental understanding
Calculate transient unbalanced forces and define forces sets as location pairs or single points
Specify design alerts that automatically highlight output values that are out of range for flow, peak pressure, velocity, and more
Compile libraries of your frequently used piping components and quickly select them from a drop down list
