When a Lowly Engineering Student Ends Up Working With One of His Exalted Professors

Gary Vanderplaats was one of my (exalted) professors in 1985 when I was a (lowly) Senior engineering student at UCSB. If not for Gary, there would be no GSC modules for AFT Fathom or AFT Arrow, and no new AFT Fathom ANS module either. Why? First, back in 1985 UCSB had a required course for ME students in Design Optimization. It was probably one of ...

You Should Combine Your Pipes

 One of the many powerful features in AFT Impulse is the ability to calculate transient forces during a waterhammer/surge event (See "Evaluating Dynamic Loads in Piping Systems Caused by Waterhammer" white paper). The resulting transient forces can be exported into a pipe stress analysis software. Pipe stress analysis care about what the trans...

What’s Old is New Again: Introducing the New Automated Networking Sizing Add-on Module

Way back 18 years ago, in February 2001, AFT introduced a groundbreaking new technology to the marketplace. We called the technology IntelliFlow® and it was implemented in a new product called AFT Mercury™. We liked to tell people that "AFT Mercury is AFT Fathom on steroids". AFT Mercury built on the foundation of AFT Fathom, and the IntelliFlow te...

An Unexpected Honor After 34 Years as an ASME Member

I remember when I joined ASME as a senior in engineering school. I remember the day I received my first copy of Mechanical Engineering magazine - and what the cover story was about (I still have a copy of that magazine!). I remember attending my first ASME conference (where I presented my first paper). It is an understatement to say that my enginee...

Raise the bar using Vacuum Breaker Valves

Vacuum breaker and air valves are useful tools in the industry for protecting pipelines against vacuum or near vacuum conditions. High points in the pipe can be susceptible to these low-pressure conditions during surge events, as pressure waves moving through the system cause a sudden pressure upsurge or downsurge. AFT Impulse can help engineers to...
