AFT Fathom is practical fluid dynamic simulation software used to calculate pressure drop and flow distribution in liquid and low velocity gas piping and ducting systems. Designed for fluid systems containing water, petroleum and refined products, chemical products, cryogens, refrigerants, and more, AFT Fathom is an indispensable tool to help you tackle your most challenging systems.

  • AFT Fathom is particularly useful for:

    • Pipe Sizing
    • Pump sizing and Selection
    • Control Valve sizing and Selection
    • Simulating System operation and component interaction
    • Evaluating heat transfer in pipes and heat exchangers
    • Troubleshooting existing systems to determine the cause of operational problems


    • Advanced hydraulic solver using Newton-Raphson matrix methods
    • Detailed modeling for centrifugal and positive displacement pumps
    - NPSH evaluation
    - Variable speed pumping
    - Impeller trimming
    - Viscosity corrections using standards from the Hydraulic Institute
    - Wire-to-water efficiency calculation including pump, motor and variable frequency drive efficiencies
    - Power usage and motor sizing
    - Energy cost calculation

    • Scenario Manager to track all design variants and operational possibilities in a single model file with data linkage
    • Integrated graphing and reporting
    • Pump vs. system curve generation including individual head curves and composite efficiency
    • Conduct thermal analysis including piping heat transfer and heat exchanger modelling
    • Calculate the costs of pipes and other components
    • Supports Newtonian and non-Newtonian fluids
    • Address viscosity and frictional changes associated with pumping non-settling solids
    • Built-in library of fluids and fittings can be extended and customized
    • Optional Chempak add-on utility provides a thermophysical database of almost 700 fluids


    • Understand the hydraulic behaviour of your system and predict how pipes, valves, pumps and other components will interact with each other
    • Evaluate the performance of new designs and assure all design requirements are met
    • Identify and correct operational problems in installed systems
    • Produce less costly, more efficient and more reliable piping systems
