I began using I-DEAS back in 1997 . Nearly a quarter century later we still do not have a free open source FEA package that is comparable to that 1997 I-DEAS. Back in 1997, I-DEAS had a huge list of cool feature, like non-linear analysis, contact elements, powerful geometry and meshing tools...
At my megacorop there are many folks who have never taken a class in CFD/FEA doing CFD/FEA work. I always perceive them as "garbage in/ garbage out" type of engineers. I would never trust their results.
In my opinion, to do FEA you must have taken a class in FEA. And same for CFD. just knowing...
I spent many years using it in the 90s and early 2000s . I liked it a lot . I think it is still better than some of the open-source free meshing tools available today. So is there any way to buy it? I assume it would have to run in some kind of old UNIX emulator?
I've always wondered why US citizens don't pursue advanced engineering degrees? They are a minority in most universities. It makes no sense because Silicon Valley is full of very high paying software engineering jobs. Other disciplines may not pay those high rates but still offer very well paid...
A user sent me and my bosses an angry email with these words:
"I HAVE PROJECT DEADLINES!!! THIS IS PREVENTING ME FROM MEETING THEM!!"
Thankfully, the issue was something not due my fault or anything and easily fixable. It is fixed now. My question is this kind of writing ever acceptable? I...
I find it annoying when colleagues engage in endless chat and email conversations when they can just talk to me to get a better answer in much less time. In face-to-face or phone I can get context, urgency and ask tangential questions. None of that is possible with chat/email.
In my opinion...
I provide IT and engineering tech. support to mechanical engineers. Often these folks want to learn more about some new programming language. They expect me to prepare a lecture and teach them how to program. This seems so inefficient to my method of just googling it.
In a few hours I can pick...
In my opinion, company's spend too much time trying to make simulation data secure. I never understood why. If someone is smart enough to reverse engineer simulation data, then they can just do the simulation themselves!
I think a lot of engineers have inflated egos and think their simulations...
Here's an interesting site that lets you run simple Abaqus models in Calculix online. See:
http://www.feacluster.com/web_calculix.php
Or to run any verification model:

Are any companies using Calculix? Seems it can do 80% of...
I got laid off after spending 16 years as an engineer at a Fortune 100 company. I was never into leadership, so remained an "individual contributor". My job career was unique in that for many years I hardly had enough work to do. It was a combination of laid back bosses and go-getter co-workers...
I was recently laid off after 17 years as an FEA support person for a large automotive OEM. The company had several hundred simulation analysts performing FEA ( structural, fatigue, CFD etc). My role was to help the analysts use the structural simulation software as well as manage the High...
I've been an individual contributor for my entire 15+ year career . I enjoy coding, simulation, and supporting other engineers who do the same. To me this is what engineering is all about. But I seem to be a minority. The vast majority of engineers spend only a few years doing actual engineering...
How come in competitive sports and arts, there is very little BS at the top levels? Almost all the pros have incredible technique that evolved from generations of pros prior to them. If any professional had a weakness, other pros would exploit that to their advantage.
But this is not the case...
I am looking for simple examples of calculus in real-world engineering problems. An example would be generating shear and bending moment diagrams for beams in civil engineering. Another would be calculating the fuel to send a rocket in space, where the weight of rocket is constantly changing as...
Just 30 years ago , workstations would cost millions of dollars , have less than 100 kb of RAM, and take several engineers working full time to operate and program.
My question is how on earth did large companies justify the cost of buying such expensive machines for such little return on...
I inherited an input deck that has this step after the first step of applying bolt pre-load. Unfortunately I am not sure I understand its purpose. fyi , node 90001 is a pre-tension node.
*STEP,INC=1
Step 2: Substitute bolt load with resultant length change
*STATIC
.1,1
*BOUNDARY, FIXED...
1. What is the exact relation between PEEQ and True strain of the material that we define in *Plastic card.
2. When I change the mesh in the contact region the PEEQ value shoots from 8% to 22%. Why there is so much difference? I have an edge contacting an edge, so perhaps this is a singularity...
While post-processing stresses, is there a way to make certain elements 'transparent' so one can see inside a 3D model?

Will all analysis software eventually be run through a web-browser? With online conferencing software one can access any remote PC and control it as though it were your own. It would be much better if FEA softwares could be available in such a way.
The customer would not have to worry about...
Once you run topology optimization, how do you interpret the element density plots to know how to size your design? I have been using anything higher than 0.3 density to include in the design as suggested in the Optistruct training.
