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...

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".

An Unexpected Honor After 34 Years as an ASME Member

Every once in a while I write a blog related to my life before AFT. Today is one of those days. And I am going to talk about swords and plowshares. This is a reference to the Old Testament book of Isaiah of moving from war to peace. First, bear with me while I tell a humorous story of the early days of AFT that relates to plows. I was applying for ...

One such book is The Undoing Project by Michael Lewis (author of several other books that have been made into major Hollywood films – including The Blind Side and The Big Short ). The Undoing Project discusses the insightful and innovative work of psychologists Daniel Kahneman and A...

What Do the New AFT Impulse 7 and Bordeaux, France Have in Common?

I think this is the third monthly blog article I have written this year from an airplane over the Atlantic Ocean. Truly I do not save my monthly blogs for airplanes. I am really busy most all the time these days. Being on an international flight means having a long, forced time disconnected from the Internet and more free time than normal to write....
