AFT Arrow 9
Significant New Features

AFT Arrow 9 incorporates over twenty new features
to make modeling gases and steam more efficient.

Analysis Setup

The System Properties window, Solution Control, Add-on Modules activation, Cost Settings, etc. have been merged into one window called the Analysis Setup window.

Multi-Scenario Graphs

Visually analyze alternatives with Multi-Scenario Graphing, comparing profile graphs from multiple scenarios on a single plot.

Output Alerts

Easily review better organized critical warnings, warnings and cautions. Double-click warnings to be taken to the specific pipe/junction referenced in the warning.


The Library Manager (previously the Database Manager) has been completely revised and now offers a consolidated way to use and customize libraries of fluids, pipe materials, junctions, etc.

Extended Time Simulation (XTS) Add-on Module

  • Model transient events such as:
    • tank filling and blowdown
    • changes in valve position
    • changes to compressor operating condition
  • Animate transient output, visualizing how parameters change over time at a point or along a flow path

Other features to look forward to

Zero-Length Connectors

Pipes can be modeled as zero-length connectors in order to represent a lossless connection between two junctions. This is useful for modeling two junctions that are directly flanged together.

Custom Unit Names

Customize the display names for engineering units of measure to accommodate language or notation differences

Equations of State

Apply the Soave-Redlich-Kwong and the Peng-Robinson equations of state as additional methods to model your fluid

Online Help System

Use the NEW online Help System for centralized documentation and examples from your browser


  • Contextually update Junction Special Conditions directly from the toolbar
  • Reset Pipes and Junctions as ‘Same as Parent Scenario’ during specification from the Workspace menu 


  • Design Alerts are grouped together on their own tab in the General Output section for easy identification
  • Spot concerns by reporting Warnings, Cautions and Design Alerts for each scenario in Multi-Scenario Output
  • Save time with enhanced Output window data loading speed


  • Batch runs of multiple scenarios now report the number of Warnings and Design Alerts in each scenario
  • Run batch runs “silently” in the background to minimize interruptions as each scenario completes
  • Search for text in Pipe and Junction Notes, useful for component specifications or intended operating conditions
