Focus on: Joints & Connections

As most structures involve some sort of jointing or connection, often running into many thousands, or even millions of connections in one individual body, the analyses involved can be among the most difficult an engineer can face. As you can imagine, there has been a significant amount of activity

Focus on: Composites

NAFEMS has been engaged in activities related to the application of numerical methods to the analysis and assessment of composite materials for many years. We have produced a significant number of resources in the field, and we've collected some of these together here. Many of the resources below

Focus on: Simulation Data Management

The effective management of simulation data and process information is increasingly important as simulation becomes a core business practice and organizations rely on simulation results as the basis for business decisions. “Simulation Data Management (SDM)” is a technology which uses database

Analysis Origins - ABAQUS

May 1st 2018 from the analysis origins series by Lynn Manning In the first of this new regular series on the roots of some of the major players in the analysis world, we take a look at the origins of HKS and ABAQUS, from its beginnings in the 1970’s, to the present day. An Englishman, a Swede

Focus on: Computational Fluid Dynamics

Computational Fluid Dynamics (CFD) is now used for a huge range of applications across all industrial areas. Its use can provide insight that is difficult, dangerous or impossible to obtain from other methods, yet the complexity of the physics of interest and numerical methods used can prevent or

Focus on: Structural Dynamics

As you would expect, NAFEMS has produced a significant number of papers, articles, presentations and much more on the subject of structural dynamics. We've collected some of the more interesting pieces together here in this email. Many of the resources below are available free for you to download,

Focus on: Manufacturing Simulation

Manufacturing Simulation covers a multitude of processes, materials, techniques, and methods. Almost every engineered object in use in industry or in our homes has undergone a transforming process taking it from a raw material to a finished product. These processes change the shape and, in many

Focus on: Optimisation

Optimisation (or optimiZation, depending on where you're from..) is everywhere. If you're involved in a design, you're involved in the optimisation process. And if you think you're not, then you're probably mistaken... NAFEMS has long had a significant focus on optimisation in engineering analysis

FEA Puzzler: a Tale of Two Analysts - Solution

This FEA puzzler, published in the April issue of Benchmark, was devised by Barna Szabo of Engineering Software Research and Development, Inc. We had a number of great responses to the challenge (business card holders are now in the post) but very few respondents spotted the singularity that

From Wind Tunnels to High Performance Computing

April 19th 2016 by The CAE Guy Back in the 1930s, the Tennessee Valley Authority (TVA) was created by congressional charter in May 1933 as a federally owned corporation in the United States and ultimately declared constitutional by the U.S. Supreme Court in 1936 [1, 2].The TVA was, in part,

Wind tunnels winding test engineers up

January 11th 2016 by The CAE Guy I confess to be continually surprised at the lack of understanding of Computational Fluid Dynamics by some (repeat, some) test engineers and managers. Not that they are not good at their jobs, but it comes up often enough that I have had to issue and edict that

Hendrix, Van Halen, Newton and Einstein

October 28th 2015 by The CAE Guy Back in the 1980s, when I was 16 or 17, I was arguing/discussing the “best” rock and roll guitarist off all time with a high school classmate of mine. While I remember it was a heated “debate” where we agreed to disagree: Long story short [1], I was advocating for

I want (CAE) candy!

July 22nd 2015 by The CAE Guy Springtime is in the air here in the Midwestern US, which means there is a transfer happening from indoor to outdoor activities. For me, that means the end of coaching volleyball to attempting to find time to ride my bicycle more (one of my New Year’s resolutions …),

The CFD interview

The CFD interview May 5th 2015 by The CAE Guy Now that I have a few months to further settle in to the aero-thermal department manager role, I have had the chance to think more about expanding the role of Computational Fluid Dynamics within the department and potentially within the rest of the

Big Time Manager

February 6th 2015 by The CAE Guy This is now what our two teenage daughters call me occasionally.Mostly in the context of when they think I am trying to get away with something. Such as: Oh, Dad thinks that since he’s a Big Time Manager now, he can do what he wants and not follow the rules. For

They've Found it! Beagle 2 Lander Found on Mars after 12 Years

They've Found it! Beagle 2 Lander Found on Mars after 12 Years January 16th 2015 Well time makes fools of us all. It didn't return calls, we didn't see it around - it was as if it had disappeared off the face of the planet (well, it had technically...), but the UK led Beagle 2 lander, which

Boyhood

October 9th 2014 by The CAE Guy Usually, when a movie is trying to convey the passage of time, say by a flashback to a character’s childhood, a young actor is used that someone, perhaps the casting director, has determined bears some resemblance to the adult actor. “Boyhood” is the story of

Simulation Driven Design: Just How Far Have We Come?

October 16th 2013 by Chad Jackson, President and Principal Analyst of Lifecycle Insights It's time for a litmus test, isn't it? We've been talking about this issue for well over a decade now. Simulation has traditionally been used for verification and validation right before testing begins. Its a

Shot-Peening Over Coffee and Pie

Shot-Peening Over Coffee and Pie September 20th 2013 by Tony Abbey, NAFEMS Training Manager Firstly, I must make an apology for yet another aviation related blog intro. On Saturday I was offered, out of the blue, a ride in an open cockpit Stearman biplane from 1942. It has a 220 hp engine, but
