Waterhammer & Surge Analysis Software

AFT Impulse6 ComputerScreen

AFT Impulse is a powerful fluid dynamic simulation tool used to calculate pressure transients in piping systems caused by waterhammer.

Designed for use in liquid systems containing:

  • Water
  • Petroleum and refined products
  • Chemical products
  • Cryogens
  • Refrigerants
  • And more

AFT Impulse is particularly useful for:

  • Ensuring that pressure extremes are within design allowables
  • Sizing and locating surge suppression equipment
  • Determining imbalanced pipe forces and sizing structural supports
  • Troubleshooting existing systems to determine the cause of operational problems
  • Evaluating the effect of pressure surges due to vapor cavity collapse

Design and Operate Your System with Greater Safety and Reliability

AFT Impulse will help…

  • Avoid potentially catastrophic effects of waterhammer and other undesirable system transients
  • Alleviate possible financial and environmental issues associated with inadequate system designs or operational procedures
  • Prevent events that have serious consequences to life and property
  • Avoid lost revenue resulting from incidents that cause down time
  • Validate the design of safety features


  • Advanced transient solver based on Method of Characteristics
  • Built-in steady-state solver to automatically initialize waterhammer transient
  • Detailed pump inertial modeling for trips and start-ups including state-of-the-art, four quadrant methods
  • Built-in library of fluids and fittings
  • Models liquid column separation caused by transient cavitation
  • Extensive cavitation modeling
  • Scenario Manager to track all design variants and operational possibilities in a single model file with data linkage
  • Comprehensive relief valve modeling
  • Integrated graphing and reporting
  • Animation features to dynamically graph transients
  • Create video files from animations to share your results
  • Generates force imbalance files that can be automatically read into CAESAR II ® and TRIFLEX ® pipe stress dynamic models
  • Built-in intelligence to guide you in building better models
