AFT Fathom

Fluid Dynamic Simulation Software

AFT Fathom is a fluid dynamic simulation software to calculate pressure drop and pipe flow distribution in liquid and low-velocity gas piping and ducting systems.

  • Accurately simulate individual system components and interaction
  • Tightly integrates equipment characteristics, analysis and output with your system’s schematic representation
  • Provides a wide array of features without sacrificing your need for a short learning curve
  • Frees you to focus on your system, not the mechanics of software manipulation
  • Significantly improves the quality of systems engineering you can achieve, leading to less costly, more efficient and more reliable piping systems

AFT Arrow

Compressible Flow Simulation Tool

AFT Arrow is a fluid dynamic simulation tool used to calculate pressure drop and flow distribution in gas piping and ducting systems.

  • Accurately simulate individual components and their interaction including effects of heat transfer, real gases and choked flow
  • Tightly integrate equipment characteristics, analysis and output with your system’s schematic representation
  • Utilize a wide array of features without sacrificing your need for a short learning curve
  • Compare the performance of new designs and assure all design requirements are met.
  • Identify and correct operational problems in installed systems
  • Significantly improve the quality of systems engineering and produces less costly, more efficient and more reliable piping systems

AFT Impulse

Waterhammer & Surge Analysis Software

AFT Impulse is a powerful dynamic simulation and analysis software used to calculate pressure surge transients in liquid piping systems caused by waterhammer

  • 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.

AFT xStream

Steam & Gas Transient Analysis Software

AFT xStream is a powerful fluid dynamic simulation tool for high-speed, acoustic transients that occur in steam and gas piping systems.

  • Accurately simulate high-speed transients in steam and gas piping systems including choked flow conditions
  • Evaluate overall system response and transient pipe forces after steam and gas turbine trips
  • Predict transient supply pressures, temperatures and flows to operating gas compressors and turbines when one trips offline
  • Simulate tank blowdowns and charging, and how long it takes to reach desired pressures
  • Predict transient pressures and flows due to heat exchanger tube ruptures
  • Easily change system input data including transient valve positions, compressor operation, control set points, pressures, temperatures and more
  • Initiate transients based on time or events in the system
