ATLAS Detector, 3D version

‘Every great advance in science has issued from audacity of imagination’ – John Dewey.

Nowadays, mankind tackles new challenges within the R&D industry. One of the leading places is hold by particle physics and its ambitious project to explain phenomena of the material universe and its origins.

The European Organization for Nuclear Research is the place where people started the quest to find this explanation by constructing the Large Hadron Collider, including its large scale detectors called ATLAS and CMS (ATLAS is 45m long, 25m high, it weighs about 7,000 tons which is almost the Eiffel Tower weigh!). It required high engineering excellence in different areas, but as a major in 3D design, I want to talk about the assembly parts.

The ATLAS collaboration gathered 169 partner institutes from 37 countries with over 3,000 physicists and engineers. Quite a lot of people huh? :) Everything started by developing 3D assembly of the detector which took 10 years and consisted in 10,000,000 sub-assemblies and parts.

3D visualization made a huge impact in calculation of heat transfer for cooling, simulation of stress and dynamical 3D modeling of installation (which in reality is one of the main concerns for engineers). How to place large and complex assemblies below 100m with 50mm clearance?

To give you an idea, the video below shows you a simulation of a 220 tones End Cap Torroid installation. In reality, lifting down such a heavy baby needs a special approach, like stopping it every five meters in order to reduce and avoid its swinging, which could cause significant damage to the surrounding assemblies.

This is a new field of engineering activity, called nuclear engineering, and it has no major ties with the traditional auto, aerospace or ship building industries. Basic difference is, in nuclear engineering, there are no standards. Thus, 3D design plays a major role as assembly or installation process is unique and based on ‘know – how’.

Does it make you feel dizzy? ^^

The Cloud: Easier, Better, Together

cloud computing dassault systemesA lot of fuss is happening right now on the Web with the launch of Google +, the company’s social network. But if you dig deeper than a mere battle between social networks, you realize that it’s the entire computing experience which is going on the Cloud: social activities, alright, but also file sharing, work spaces and other services are all more and more on the Cloud.

But think about it… What’s the Cloud goal but to bring people closer? Social networks such as Facebook are the tip of the iceberg and represent it perfectly: it brings the social back! :-)

Cloud: the Bigger Picture

Of course it’s the same for the CAD and PLM industries. More than ever, people need to work together from different places and different workstations. Thus, there is a double objective: facilitate the work environment and share with others. Oleg Shilovitsky stated rightfully that we should “work together without thinking about how collaborative or social a particular software is performing”.

My point is that if it’s got to be natural, it’s got to be easier, simpler and a part of a whole system that drives the work experience. Generation Z is the only one (so far) which is born in that kind of environment and for them it will be natural to have everything in one place, easily. And eventually, that’s where Clouds are all about I guess…

What do you think?



Our Holidays Program: Experience Ancient Egypt!

Khufu Reborn Pyramid Egypt Djedi

We already talked about it: we love pyramids! And actually we love them so much we thought you’d like to experience them as well… in 3D (and even on your 3D TV!). So Dassault Systèmes developed an application to truly go back in time and visit old Egypt.

Still skeptical? Let me tell you, you’ve never seen a lecture this fascinating: the topic’s hot, the technology to showcase it kicks ass and whenever you have a question, just stop and hang around to explore the pyramid and get your questions answered! And to quote our friends from the BBC:

we may be on the very edge of uncovering some of our past’s greatest secrets.

So if you feel like going on holidays, discovering pyramids and ancient Egypt just like they were 4,500 years ago, just click here! Otherwise, if you don’t have time to browse through the whole adventure, I thought I’d split it so that you can pick your choice! ;-)

First part is called “the two enigmas of the Great Pyramid” and talks about how the pyramid was built, especially regarding other pyramids. So if you want to have an overview of what’s so mysterious about Khufu’s pyramid, I’d recommend you take a look at this part.

Second part is about “the genius of the builders”. Basically, if you want to learn about the architectural side of the pyramid construction, head there! Plus, it’s divided in three parts so you can understand the whole construction process (it’s my favorite part!).

Third part is named “seventy days to be reborn” and explains the whole process behind Khufu’s preparation before being put inside the pyramid. You’d like to see the rituals? That’s over here!

Fourth part is called “the paths to eternity” and gives you Jean Pierre Houdin’s point of view about the King’s chamber and its construction secret! (My second favorite part… The architects back then were truly geniuses!)

The final part “simply” allows you to travel completely freely around the pyramid and its construction site.

Enjoy the ride and tell us what you thought about that! :wink:



PS: just an advice, during the loading process, be sure to say “no” if your browser asks if you want to stop the 3Dvia plug-in. It happens sometimes but always loads afterwards… I’m guessing this is ancient Gods testing if you’re worth seeing their land! ;-)

PPS: if you want to share the adventure, feel free to do so! Here’s the link: www.3ds.com/khufu
