AFT Software Products
Whether you're modeling gas or liquid piping systems, perfecting your system design, studying your system's transient behavior or need fluid property data, AFT has the engineering software tools for you. Our industry-leading fluid dynamic simulation software is used by a variety of industries around the world to develop design solutions and troubleshoot existing systems.  

Engineers use AFT for several reasons. The best reason is that AFT is a highly accurate calculation software that saves engineers from using extensive hand calculations or spreadsheets. What used to take days or weeks is able to be accomplished with AFT's pipe flow software in a short amount of time. The man-hours companies save by using AFT modeling and simulation software pays for software several times over. 

We might be biased, but when engineers tell us it is the best fluid flow software on the market... we can't argue. Our staff of engineers has worked for years to ensure it is a tool which delivers solid modeling calculations, incorporates robust features, and give users an intuitive interface.

We look forward to working with you.

AFT Fathom

AFT Fathom is used to calculate pressure drop and flow distribution in liquid and low-velocity gas piping and ducting systems. Includes heat transfer, time simulation, automatic goal seeking, cost calculations and built-in tools for modeling piping system components.

AFT Fathom Add-On Modules

Settling Slurry
Models the effects of pumping fluids containing settling solids using the Wilson/GIW method

AFT Arrow

AFT Arrow is used to calculate pressure drop and flow distribution in gas piping and ducting systems. Including adiabatic, isothermal, heat transfer, sonic choking, automatic goal seeking, cost calculations and built-in tools for modeling piping system components

AFT Arrow Add-On Modules

Goal Seek and Control
Identifies input parameters that yield desired output values and simulates control functions

AFT Impulse

Analysis software used to calculate pressure surge transients in liquid piping systems caused by waterhammer. Models and simulates your pipe system to help avoid the potentially catastrophic effects of waterhammer and undesirable system transients

AFT Impulse Add-On Modules

Pulsation Frequency Analysis
Helps identify and avoid resonant frequencies in systems, especially in those caused by positive displacement pumps.

AFT xStream

AFT xStream is a powerful fluid dynamic simulation tool for high-speed, acoustic transients that occur in steam and gas piping systems. Uncertainty in design and operations costs money and time. Now you can accurately simulate how your steam and gas systems will respond to potentially harmful transient events.

AFT xStream Add-On Modules

Pulsation Frequency Analysis
Helps identify and avoid resonant frequencies in systems, especially in those caused by reciprocating compressors.


A chemical property database of up to 700 fluids and 600 gases with mixing capability.

Nuclear Verification & Validation

Archon Engineering has developed Nuclear Verification and Validation packages to enable the use of either AFT Fathom, AFT Arrow or AFT Impulse software in safety-related applications in the nuclear industry.


Teaching pipe flow analysis and modeling can be easy. Once students learn the basic methodology, instructors are able to show their classes more advanced practices using our modeling software. Take advantage of these steep discounts on full licenses for classroom instructional use.

Interested in learning more about your favorite AFT products?
You're in luck! Below are a few options. Contact us for any further questions.

Free Demos

Sometimes you just have to jump in and work with it yourself. AFT provides a limited version of our software so you can get the basic idea of how it works. Note: these demos are not meant to show you all of the bells and whistles.

Introductory Webinars

Watch a recorded webinar and meet our products! AFT engineers will give you insight into how the products work. Additional webinars help you solve project issues so you can model, analyze, and simulate safe and efficient piping and ducting systems. 

Common Interface

AFT models can be imported between AFT products. For example, build your steady-state model in AFT Fathom, then use that same model in AFT Impulse to analyze the surge transients. Contact us for a live walk-thru or an evaluation license.
