The Opposite of Good Vibrations - Evaluating FIV, AIV, FIP Guidelines from AFT Fathom and AFT Arrow
Learn how to use AFT Fathom and AFT Arrow to help calculate the Likelihood of Failure (LOF) for Flow Induced Vibration (FIV), Acoustic Induced Vibration (AIV), and Flow Induced Pulsation (FIP) in accordance with Energy Institute Guidelines to avoid v...
What Is Transient Analysis?
You're tasked to perform a transient analysis of a piping system and it would be really helpful if there was a good software tool out there to help you. Well, you've come to the right place because AFT has great solutions! ...
Know Your Pump & System Curves - Part 3
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 s...
Digital Twin – Identical or Fraternal?
When I was a child, I was jealous of twins. I thought how cool it would be to have a twin. I had twin cousins a few years older than I was that I saw on a frequent basis. I always got them confused. Which one was Roger, and which one was Ronny? A buz...
When I wrote AFT Impulse 1 back in 1996, I slipped in an undocumented feature to make it capable of modeling the first waterhammer project I did in industry. Since then, this feature had a secret (i.e., undocumented) way of being enabled. AFT Impulse 8 will be released any day, and we have finally made this feature accessible to all. In the User Op...
In June 2020, AFT's Reinaldo Pinto presented the webinar Calculating Transient Forces for Pipe Stress Analysis. The webinar focused on generating unbalanced forces due to surge in AFT Impulse and exporting them to CAESAR-II. During the webinar, 28 questions were asked. Below are the responses.

I am a child of the Space Age. When I was a young boy we had one color television. On one day I was watching the original Star Trek TV series with my father (through reruns), then the next day watching the Apollo missions take men to the Moon. The fiction and reality of space travel were intermixed in my young mind of around 1970. Fast forward to t...
Really? Another blog about features in AFT software? Yes, really. And there is a good reason for it. Because this new feature in AFT Impulse 8 will change your life. Well, it may not change your life, but it will forever change how you do your waterhammer analysis. I am talking about the new multi-scenario graphing and animation feature. This brand...
Every year countless people make predictions on a countless number of things. For example, every year there are people who predict a financial crisis of some kind. There are people who predict significant natural disasters. And there are people who predict a health crisis – such as the current COVID-19 pandemic. When one of these unusual events act...
Like most of you, I have no expert advice to give related to the current worldwide pandemic caused by COVID-19 – also known as the Coronavirus. Thus, I won't presume to offer advice or wisdom on that topic. But everyone is talking about, reacting to and being affected by the pandemic. It seems almost insensitive to not acknowledge that. As the Pres...
Sometimes you just get lucky. When I accepted my first engineering job, I only knew that I wanted to work on fluid and thermal engineering. And wow did I ever get to do that! I was fortunate to work on a wide variety of applications in fluid and thermal behavior in cryogenic rocket design. Super cool. But I got lucky in another even more important ...
