Having some trouble getting your modelling under control? This blog will discuss some tips on how to properly use a control valve in AFT Fathom and how to interpret some common control valve warnings. For simplicity this blog will primarily discuss control valves in the context of AFT Fathom. However, the concepts discussed in this blog also apply ...

AFT strives to make our interface intuitive and user-friendly, but we know that pipe flow modeling can be complex. That's why the AFT team have worked to put together the AFT documentation portal, a new centralized place to find all of our help resources for AFT Fathom, AFT Arrow, AFT Impulse, and AFT xStream. Here's a quick summary of what you can...

 New versions of AFT Fathom, AFT Arrow, and AFT Impulse are being released in the upcoming months. This round of releases focuses on major interface changes which will improve user efficiency. Check out these new features and improvements that will be in Fathom 12, Arrow 9 and Impulse 9. Analysis Setup To make the modelling process simple...

You've built a model, verified all of the inputs, and now you have results, but how are you going to organize and present these results? Here is a quick guide to some of the customization available in AFT software for displaying output and exporting your data using the Output, Visual Report, and Graph Results windows. The screenshots and examples f...

Trying to run a model and running into convergence errors? Here are a few common tips to help with model convergence for AFT Fathom, AFT Arrow, and the steady state modes for AFT Impulse and AFT xStream. Though these tips will not work for all models, they have helped with many of the steady state convergence cases that have come through the AFT su...

For gas systems flow is driven either by a pressure difference, or by a turbomachine. AFT Arrow allows users to model turbomachines such as fans, blowers and compressors. For this blog we'll talk about what differentiates these three options, and how to model them using AFT Arrow.    Definitions and Types Fans, blowers and compressors all...

While thinking in terms of pressure is often intuitive for engineers, thinking in terms of head can be more challenging. You may be surprised by the number of cases and questions that come to the support team here at AFT about the basic definition of head, and how it relates to hydraulic modeling. Let's get back to the basics with how head is defin...
