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...

Let's face it, specifying every pipe size, length, elevation, pump curve and component loss in a hydraulic model can be tedious. While essential to fully defining a system, often there is avoidable redundancy during model specification. The Global Edit feature helps to ease this tedium and redundant specification by mass updating overlapping parame...

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...

Eductors, also known as jet pumps, are a clever way to pump a liquid without any rotating equipment, motors, shafts, or electricity using only the momentum from a supply fluid. However, these interesting pumps can quickly become confusing especially when trying to define them in AFT Fathom. In this blog we will explore exactly how eductors work and...

Non-Newtonian fluids are something almost every elementary school student is familiar with. Mixing cornstarch and water to create a liquid that acts as a solid is an experiment which has captured the attention of children (and adults) for generations. The Discovery Channel show Mythbusters even showed Adam Savage walking across a tub of cornstarch ...

In the final "Know Your Pump & System Curves" blog series, I am going to discuss the complexities behind pump vs. system curves for systems with pumps in series and parallel configurations. Multiple pumps in series configurations are relatively straight-forward and will be discussed briefly. Operating pumps in parallel configuration involve a f...
