Gentlemen, we have a plane! Big Frog.

A few months ago, we welcomed a project with the strange name of Big Frog in the Passion for Innovation program.  Big Frog is an audacious project to compete in the Reno Air Races with a diesel engine and yet win thanks to faster, greener aerospace design. 

For a limited time Big Frog itself is on display at Dassault Systèmes Campus.  Boy was everyone surprised Monday morning when they saw the splendid, shiny, black carbon aircraft on display! 

Yes, using our CATIA and SIMULIA solutions, the Big Frog team integrated the diesel SMA engine to this 100 percent composite racer and brought several betterments to the aircraft.  All these operations were conducted with the help of our experts.

We were delighted when the Big Frog team decided to display the aircraft at Dassault Systèmes to celebrate this important step on their road to Reno.   We’re proud to have this “Formula 1 with wings” on site!

It seems that Reno Air Races organizers have also understood that something special was cooking here. As a matter of  fact, Big Frog has just just been moved up from Sport Class to Super Sport Class, a development that has fired up the team with even greater enthusiasm.

There’s still much work and training to do before the race in September 2010.  Reno Air Races are introduced by the ritual sentence “Gentlemen, you have a race” issued from the pace aircraft. Today, we cas proudly say “Gentlemen, we have a plane!”

Best,

Zaha Hadid: Vision to Reality

What a passionate life and career.

I’m lucky to have crossed the path of Zaha Hadid early on her way to become one of today’s most acclaimed architects.

Back in the mid-1980’s at the architecture department at the University in Stuttgart, Germany she gave an evening lecture and showed us stunning pictures of her visionary building designs and sculptures. I was there attending the presentation to build my culture and compliment a scientific education I enjoyed during the day.

One of the projects Zaha Hadid presented was her first internationally celebrated work, the 1983 first prize winner with the design of “The Peak”. It’s a luxurious leisure club in Hongkong, where she was quoted referring to it as “architecture as a knife cutting through the site.”

We were all blown away from the boldness of her work – so extremely advanced that until then these projects remained unbuilt images and models, as nobody dared to construct them.

Around 1993 my wife, who’s also an interior architect, brought me along to visit Madame Hadid’s first fully constructed building.

The furniture and design firm Vitra had engaged her to build a fire station as part of a museum and seminar center in Weil am Rhein, close to the country triangle Switzerland, France and Germany. It was so much fun to walk through the building and to experience spaces at extreme angles and curves. I recall that being inside this building lent a particular sentiment far different from the usual 90° feeling in a normal room. I was impressed.

Thereafter I lost track of Zaha Hadid and – poufff – by 2004 she had become the first female recipient of the Pritzker prize and transitioned to an architectural celebrity.

And she is still producing those visionary designs which now are realized into totally impressive buildings – one after the other. Her approach to architecture has been described as the one of a painter who uses computers.

Zaha Hadid Architects (ZHA), her London-based firm, was founded in 1980 and now employs 300 professionals. Their challenge is immense: taking Mme Hadid’s ideas into a reality made of steel, glass, concrete and composite materials, while taking into account physics and engineering constraints, within the economic boundaries of timing, budget and quality control.

You might have seen the recent press announcement about ZHA extending the use of Digital Project (DP). ZHA is using a Building Information Management solution with CATIA as the core design engine from Dassault Systèmes’ partner Gehry Technologies.

What started as just a trial software usage at ZHA (offered by her friend and fellow architect Frank Gehry) to let her team explore the possibilities of 3D design has concluded in their decision to rely on Digital Project as the system to help them managing their extremely complex projects. This includes capturing original designs with extreme curves and surfaces into the CATIA modeler, building 3D assemblies fit for manufacturing, and managing changes efficiently all the way from idea to delivery.

Why is this exciting news?

I believe that ZHA’s commitment confirms the trend that after leading architectural powerhouses such as SOM (e.g. Al-Rajhi Bank Headquarters in Riyadh) and ARUP (e.g. Birds nest Olympic stadium in Beijing) started to rely on DP as an end-to-end solution to support architectural project delivery, now even the explicitly artistic representatives of their genre such as Zaha Hadid select it as master tool and trust it to capture their architectural vision to become reality. Is this the resolution of antagonism between art and technology for architecture?

What do you think is next?

Best,

3D City Management: Traffic!

By Bruno

Hello dear 3D Perspectives readers and bloggers,

This is a follow up on 3D City Management as promised in my previous post. In the last episode I explained how noise could be simulated and visualized in a 3D scene.

Today, I’d like to talk about another aspect of our everyday urban life. Traffic!

Most of us spend a lot of time in traffic and wonder how car flow could be optimized and made more fluid, saving us precious time. The old-fashioned way to create roads and traffic infrastructure is by building roads that connect point A to point B.

But if we want to create a city with a sustainable design and framework, we need to consider different elements before finalizing decisions: noise, air pollution, carbon footprint, energy consumption, etc. As a result, decisions about road infrastructure become more complex and need to be supported by simulation software that can optimize the combination of all these factors.

We are currently working with talented people at a French public research institute focused on traffic simulation: LICIT (ENTPE/INRETS) and LTE (INRETS) who have developed a dynamic traffic simulation application (SYMUBRUIT). The value of their approach is to be able to open their model to dynamic attributes like, speed, size of the streets and random events.

The outcome of these studies gives a much better understanding on the decisions that need to be made to optimize traffic and environmental impact.

For example the result of a recent study demonstrated that a roundabout reduced noise by 60 percent, fuel consumption by 80 percent, and the fluidity of the traffic was improved by 30 percent.

Now I’m not sure all of us believe that roundabouts are the best solutions everywhere!

We all need to be convinced. A realistic 3D simulation would help to better understand these studies. That is why, in cooperation with the CSTB (MoDev), the SYMABRUIT results can be rendered in a 3D scene with modifiable simulation attributes. It becomes much easier to understand.

See for yourself in the video below. Here you can see the impact of a traffic light being moved combined with a modification of the average number of cars per hour.

Once again we see that building and city management require powerful simulation capabilities combined with a powerful way to communicate the results to citizens. This is where the potential of 3D can be fully exploited. It’s also a direction we are exploring at Dassault Systèmes.

This post concludes this first series on 3D City Management. I hope you enjoyed it! Stay tuned, I’ll announce the next series soon.

See you soon!
