AFT Fathom™ 13

Steady State Pipe Flow Modeling Software

AFT Fathom is a fluid dynamic simulation software for engineers, used 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

Experiment with operating conditions and scenarios
  • Easily change system input data, including valve positions, pump operation, control set points, pressures, temperatures, and more
  • Model a wide range of system components for both design and operational cases
  • Vary your system line-up: open/close pipes and valves, turn pumps on or off, set control valves to fail position
  • Specify design alerts that automatically highlight output values that are out of range for flow, pressure, velocity, pump efficiency, and more
  • Find pump data from online manufacturer catalogs
  • Compile libraries of your frequently used piping components and select them from a drop-down list
  • Address the viscosity and frictional changes associated with pumping non-settling slurries and a variety of other non-Newtonian fluids
  • Evaluate codes and industry standards applied in the model
  • Calculate the cost of system pipes and components as well as energy cost
  • Import piping layouts from:
    • CAESAR II® Neutral files supported by AutoPIPE®, ROHR2, TRIFLEX®, etc.
    • PCF Files supported by AutoCAD Plant 3D®, SmartPlant®,  CADWorx®, and other GIS shapefiles supported by ArcGis, etc.
  • Import and export files in EPANET format
  • Clearly import Excel data into multiple scenarios and export with the Excel Export Manager
  • Export data to evaluate Flow Induced Vibration (FIV) according to Energy Institute Standards

  • Consider viscosity and frictional effects from non-Newtonian viscosity models or non-settling slurries
  • Model your centrifugal and positive displacement pumps to account for
    • Shifting performance curves through variable speed control and impeller trimming
    • Viscosity corrections using standards from the Hydraulic Institute
    • Wire-to-water efficiency including pump, motor and variable frequency drive efficiencies, used to size motors and evaluate power usage
    • Acceleration head loss for positive displacement pumps
    • NPSH evaluation
  • Size motors and evaluate power usage by considering wire-to-water efficiency (including pump, motor and VFD efficiencies)
  • Account for heat transfer effects in pipes and heat exchangers
  • Ensure a design adheres to industry standards such as API 526, ANSI/HI 9.6.3, API 610, or NFPA Standards
  • Import piping layouts from CAESAR II® Neutral files, PCF Files, and GIS shapefiles regardless of source
  • Integrate with Excel to import model data and export output data
  • Built-in libraries of fluids (including NIST REFPROP and ASME Steam Tables) and fittings which can be extended and customized
  • Optional Chempak add-on utility provides a thermophysical database of almost 700 fluids

How does it work?

AFT Fathom’s hydraulic solution engine uses the Newton-Raphson matrix iteration method plus proprietary methods developed by AFT to solve pipe flow and duct flow applications. AFT Fathom uses the Bernoulli’s Equation and Reynolds Number-based relationships for pipe friction calculation.
