Renault Group and Dassault Systèmes strengthen partnership

By Leave a Comment

Dassault Systèmes and Renault Group announced they are reinforcing their 20-year collaboration with a new partnership contributing to Renault Group’s strategic plan “Renaulution” focused on value creation.

In a first-of-a-kind deployment for an industrial company of this scale, Renault Group is adopting Dassault Systèmes’ 3DEXPERIENCE platform on the cloud globally, to develop programs for new vehicles and mobility services. This enterprise platform will provide Renault with a new backbone for sharing, in real time, all product-related data throughout the product life cycle, and for managing the virtual twins of its diverse product configurations.

Major trends in the transportation and mobility industry – increasing regulatory constraints, product complexity, electrification, connectivity, sustainability and new mobility services – require accelerating the interconnection of different functions and expertise within an agile and collaborative ecosystem.

Renault Group will deploy its use of the 3DEXPERIENCE platform on the cloud to more than 20,000 employees in vehicle development functions such as Design, Product Engineering, Industrial Process Engineering, Parts and Materials Purchasing, Costing and Quality. Connected to the cloud, the platform will provide access to the same systems and software, 3D modelling and simulations, updated in real time across the world. The large-scale collaboration based on virtual twins will improve data sharing between the different functions and agility within the company, while reducing costs and vehicle development time by around one year. Renault Group will benefit from continuous technological evolutions and functional enrichment of the collaborative 3DEXPERIENCE platform on the cloud.

“Our decision to adopt the 3DEXPERIENCE platform on the cloud demonstrates our belief in the leadership role of engineering and digital in our ‘Renaulution’. Our shift toward becoming a technology, services and energy company must be collaborative,” said Luca de Meo, CEO, Renault Group. “The 3DEXPERIENCE platform connects engineering to all disciplines in one digital company. We will gain agility, speed, and effectiveness to develop new mobility faster than ever.”

“Sustainable innovation is in the DNA of both companies. Renault Group’s transformation will radically change the mobility industry going forward, much like the first virtual development of a commercial passenger airplane did for all industries in 1989. We are fully engaged in this partnership and in supporting Renault Group’s success,” said Bernard Charlès, Vice Chairman and CEO, Dassault Systèmes. “Today’s industrial ecosystems are no longer linear, but circular. Innovating requires new collaborative approaches with virtual twin experiences that address and include the entire evolving value chain. As Renault Group moves to an enterprise platform, our partnership confirms that the 3DEXPERIENCE platform goes beyond vehicle creation and production. It is a lever to drive the industry toward the delivery of new, sustainable mobility experiences.”

3D CAD & CAE manufacturer catalogs powered by CADENAS now available in SOLIDWORKS Electrical 3D

By Leave a Comment

Good news for all electrical engineers and component manufacturers: SOLIDWORKS Electrical 3D joins the long list of software solutions for CAD, CAE, PLM and simulation that offer direct access to thousands of digital manufacturer catalogs powered by CADENAS. Millions of manufacturer-verified 3D CAD and CAE data are now directly integrated into the popular solution for electromechanical design. By integrating the Strategic Parts Management PARTsolutions, users have access to not only the countless 3D CAD models. They also benefit from an extensive selection of standards as well as intelligent functions for managing and finding proprietary, purchased and standard parts.

Optimized cooperation between MCAD and ECAD divisions
The electrical design situation is different from mechanical design, where not only, but above all, the geometries of the digital components are decisive. Electrical engineers need information about circuit diagram symbols, connections, component types (connector, cable, standard component, terminal, etc.) or parent-child relationships when selecting the appropriate component. The product models must also provide information on which connectors are compatible or how the installed components are to be correctly dimensioned in relation to each other. If this data is not stored within the CAD model, it must be compiled in a time-consuming process from various sources. Multi CAD capable product data based on CADENAS technology enables seamless collaboration between ECAD and MCAD, as component information can easily be transferred between mechanical and electrical design – without loss of information.

SOLIDWORKS Electrical 3D by Dassault Systèmes provides additional support for smooth electromechanical collaboration. With the software module, design data of circuit diagrams can be integrated bidirectionally into the 3D model of a machine or assembly. ECAD components such as wires, cables and harnesses can be easily positioned and automatically routed in the 3D MCAD model. Design and bill of materials are also synchronized in real time, minimizing sources of error.

The software indicates which connectors are compatible or how the installed components are to be correctly dimensioned in relation to each other. If this data is not stored within the CAD model, it must be compiled in a time-consuming process from various sources. Multi CAD capable product data based on CADENAS technology enables seamless collaboration between ECAD and MCAD, as component information can easily be transferred between mechanical and electrical design – without loss of information.

XVL on 3DEXPERIENCE is released after a three-year joint development project

By Leave a Comment

After a three-year joint development project between Dassault Systèmes and Lattice Technology Co. Ltd, working with Toyota Motor Corporation, native XVL on the 3DEXPERIENCE platform for Japan is available now (worldwide release is planned for 2022). The inclusion of native XVL with the platform enables increased usability downstream of product design in areas such as production engineering and service.

“Users can instantly and directly access XVL data on 3DEXPERIENCE. The members of design and production engineering feel that they have reached a new level of 3D utilization. The timeliness achieved in this project is very important in terms of accumulating the reduction of one small operation and not disturbing designers’ thinking“, said Hiroshi Kawazoe, Director/Toyota Systems Corp.

The source for this press release was a live interview between Hiroshi Kawazoe, Director/Toyota Systems Corp., Stephane Declee, ENOVIA CEO/Dassault Systèmes and Hiroshi Toriya, CEO/Lattice Technology Co. Ltd.
Toyota Systems: Different Needs for Design, Production Engineering & Services

“In Toyota, CATIA is widely used in the design area, and XVL is widely used in the production engineering and service document areas. When these two solutions are closely linked on 3DEXPERIENCE, I think Toyota might have bigger benefit from them,” said Hiroshi Toriya, CEO/Lattice Technology Co., Ltd.

“We need both the technical role of creating content, and a simple mechanism that many people can use for taking advantage of the content,” said Hiroshi Kawazoe/Toyota.

“Toyota uses CATIA for the former and XVL for the latter. It has great meaning that the technical department creates detailed data and people in production site or factory, suppliers can use lightweight 3D and simple tools even from places where IT infrastructure is not sufficient”, said Kawazoe.

“Also, such a situation greatly expands the range of 3D utilization. In particular, Lattice, a purely Japanese-like company, has been very effective developing applications that meet the specific needs of the Toyota production process”, Kawazoe went on to say.
Dassault: Need for Agility & Resiliency

“Agility and resiliency will become even more important in the future. Many manufacturing companies are considering how they can change the way of work according to these goals. The way of work in design and production will surely change”, said Stephane Declee, ENOVIA CEO/Dassault Systèmes“. It is necessary to reform the way of working so that we can provide appropriate information to people and collaborate with each other wherever they are. This also leads to remote work and to work anywhere. This is true not only for Dassault and its customers, but also for partners. In addition, “Cloud” will become a keyword in new measures for the design and production fields”, said Declee/ENOVIA.

”Global collaboration is also very important for the themes we are working on with Toyota Motor Corporation. Not only online but also offline collaboration is essential. That means delivering correct information based on 3D data. With 3D, various members can have a common understanding intuitively and without misunderstandings. Such aspects of 3D data will become so important as to be called indispensable”, said Kawazoe/Toyota.
XVL & The 3DEXPERIENCE Platform

XVL is an important addition as a native format available on the 3DEXPERIENCE platform for purposes other than design because it is extremely lightweight (about 1/100th the CAD file size) and maintains CAD level accuracy.

XVL can also accommodate all major CAD formats in a single representation, meaning SOLIDWORKS® models, CATIA® models, and models from other CAD systems can be combined into a single model, that is accurate for performing work outside of the design department from manufacturing planning, to assembly simulation, creating work/service instructions, and any technical documentation that needs the 3D model.

The process is seamless. Users can download any model in XVL format, regardless of its origin.

“Now XVL and CATIA data exist in a 1-to-1 state on 3DEXPERIENCE. Non-CAD users can get their job done while sharing the correct 3D data globally, both online and offline.”, said Toriya/Lattice.

“As a result of this strong partnership and great efforts by all three companies, I believe that the best collaborative solution has been achieved. XVL can be managed as a native format on the 3DEXPERIENCE platform, said Declee, ENOVIA

Dassault Systèmes and “The Inventor” launch the “3D Design Challenge” celebrating Leonardo da Vinci

By Leave a Comment

In celebration of Leonardo da Vinci’s ingenuity that has fascinated the world for centuries, Dassault Systèmes’ 3DEXPERIENCE Lab has teamed up with “The Inventor” – a new animated film about Leonardo from Jim Capobianco, the Academy Award-nominated writer of the Pixar film “Ratatouille” – Foliascope and Château du Clos Lucé – Parc Leonardo da Vinci to launch a new “3D Design Challenge” to bring Leonardo’s drawings to life.

The challenge invites individuals to showcase their 3D skills by using Dassault Systèmes’ 3D digital applications – which have enabled the design and engineering of groundbreaking industrial innovations for 40 years – to digitally reconstruct an invention from Leonardo’s codices.

Five winners will be selected based on how closely the 3D model resembles the original drawing, how well the model articulates the movements intended by Leonardo in the corresponding sketch, and how easily the model could be 3D printed.  Each winner will receive a 3D-printed version of their model, and gain access to Dassault Systèmes’ xDesign application for one year.

The winning designs will also be featured in the upcoming “The Inventor” stop-motion animated film that follows the incredible journey of Leonardo in a humorous and inventive story for the whole family, voiced by Stephen Fry as Leonardo, Daisy Ridley as Princess Marguerite de Navarre, and Marion Cotillard as Louise de Savoy.

The 3D Design Challenge is being run fully online from February 12-April 15, 2021 in the Open Codex Community.  Since 2012, this community has been bringing together designers, engineers, makers, hobbyists, students, teachers and others to draw inspiration from the past and use the virtual world to link imagination with innovation through international challenges focused on recreating Leonardo’s inventions in 3D.

Participants in the 3D Design Challenge must choose one of the 10 codices listed in the community and use CATIA, SOLIDWORKS or xDesign applications to accurately create a 3D working model of the drawing in real-life dimensions, then submit their entry by posting an explanation of how the final design works and uploading the 3D model in the online community.  These applications, powered by Dassault Systèmes’ 3DEXPERIENCE platform, enable users to digitally create, test and optimize the structure, mechanics and system.

In line with the 3DEXPERIENCE Lab’s collective intelligence and cross-collaborative approach to strengthen society’s future of creation, participants are encouraged to interact with other designers, participants and fans of Leonardo in the community throughout the challenge.

Generative design for flow applications

By Leave a Comment

Flow driven generative designer is a new application from Dassault Systèmes. Its intended use is to give users or designers access to simulation capabilities for fluid optimization.

As many designers know, the process of creating a part is typically based on experience and intuition. Generative design, however, offers a different approach. Generative design programs use boundary conditions, set by the designer, to drive and simulate how a part should look. Applications for flow driven generative design include powertrain design, HVAC, jet propulsion, injection molding, and valve and piping design.

Within the program, designers are encouraged to ask different questions. For example, rather than ask, ‘Does this shape meet the requirements?’, the question changes to ‘Which shape best meets the requirements?’

According to Colin Swearingen, generative design expert at Dassault Systèmes, “optimizing fluid flow for a particular component is a difficult process as it incorporates a number of aspects of engineering.” These aspects create an “over-the-wall” process where various engineering disciplines such as CAD, analysis, simulation, manufacturing, PLM and so on, are siloed and there is little collaboration.

One of the risks of siloed engineering is an increase in the number of data translation errors that can compromise a design. Another drawback is the lack of expertise in more than one engineering discipline. Few companies have designers who are experts in CAD, CFD, and analysis.

Thus, in a typical traditional design process, a designer begins with a design space and sets up boundary conditions. In the case of fluid, what are the inlet conditions and what are the outlet conditions? Are there any other restraints that need to be applied to the model?
Then the design is handed off to an analyst, who must then mesh the data and prepare it for a CFD model run.

The new shape also needs to be validated. In a typical design process, that’s a different tool that is used to compute the flow analysis as opposed to optimizing the shape to begin with.
So, designers do their best version of the design. However, it quickly becomes an iterative process every time a change is made.

The flow driven generative program is in the 3DEXPERIENCE platform, which also includes other engineering tools, such as CAD, simulation, analysis, optimization, and manufacturing. All of these are unified into one environment so that a designer can streamline the design process. This platform makes the process intuitive, helping users optimize the design earlier and eliminates all the data translations required in other tools and platforms.

In Flow driven generative, once the designer is satisfied with the initial iteration of the design, they simply click a button to begin a simulation. Then, they can run a flow analysis without leaving the design program.

File exchange is not needed in this process, and no data translation is necessary. Said Swearingen, “It’s intuitive, easy to use, and we really streamline the process. What we see is about a 10-times faster turnaround time.”

The program includes a design assistant that prompts the designer to answer specific boundary questions that help the program create a design.

Noted Swearingen, the program leverages best in class TOSCA fluid technology in the background. Tosca fluid and many of the Tosca applications are typically known as an expert tool. However, that’s being run in the background here. The designer is getting access to this simulation capability without needing to be a full-fledged expert in the program.

The goal of the Flow driven generative program is to remove the bottlenecks that make it cost prohibitive to explore optimized parts. Another goal is to develop a seamless collaboration with design and simulation departments. “In a unified environment,” said Swearingen, “it’s enabling collaboration and opening doors for users in a much more streamlined and efficient manner, to tackle the problems that arise with this type of workflow.”

Developing a zero-emission, all-electric regional commuter aircraft

By Leave a Comment

Dassault Systèmes announced that the electric air mobility pioneer, Eviation Aircraft, used the 3DEXPERIENCE platform on the cloud to develop the first prototype of its zero-emission, all-electric regional commuter aircraft – Alice – in two years.

In the race to create and commercialize new categories of sustainable air mobility systems, Eviation Aircraft accelerated the prototype’s development by deploying the “Reinvent the Sky” industry solution experience based on the 3DEXPERIENCE platform. This scalable cloud solution supported the company’s holistic approach to 3D, composite design and flow simulation with improved collaboration while securing data in a single, standards-based environment.

“The electrification of aircraft isn’t a question of if, but when. As we aim to make clean regional air travel accessible for all, we needed to be able to make a product that people trust, sit in and fly, and do it quickly,” said Omer Bar-Yohay, CEO, Eviation Aircraft. “The right way to go about it was to use tools that we would want to use in the long run, and to work in the cloud to ensure fast, secure access and global collaboration. When we selected the 3DEXPERIENCE platform, we were an early-stage startup with limited resources and time. We’ve developed our commercial-stage prototype faster than we imagined, and have already signed our first customer in the U.S.”

Eviation Aircraft realized that transforming a prototype into a product that can be manufactured by the hundreds each year would require empowering its engineers with the long-term knowledge and know-how to build it to maturity for the next generation.

Once commercialized, Alice will be the world’s first all-electric regional commuter aircraft, capable of carrying nine passengers and two crew on a single charge for 650 miles at 10,000 feet.

–Make Part Flexible is a new capability that allows users to display the same part in different conditions in the same assembly. For example, the same spring exists twice in the same assembly, but in two different conditions – compressed and not compressed. Make Part Flexible is useful in many design applications such as springs, bellows, hinges, o-rings and just about any part that can flex or change condition.

–Improvements to SOLIDWORKS PDM, the SOLIDWORKS Electrical connector and a new SOLIDWORKS PCB connector allow for complete electronics design and data management – including the secure storage, indexing and versioning of all user data – while enabling tighter collaboration between ECAD and MCAD teams.

With SOLIDWORKS 2020, and the 3DEXPERIENCE.WORKS portfolio, the 3DEXPERIENCE platform offers a growing set of cloud-based solutions that work together to help manage every aspect of developing concepts, designing products, and manufacturing and delivering them. Solutions like 3D Sculptor, which includes the xShape (sub division modeling) application, 3D Creator featuring the xDesign (parametric modeling) application, 3D Component Designer (data management), Project Planner, and Structural Professional Engineer (advanced simulation), enable users to reduce friction in their design to manufacturing process.

As announced at SOLIDWORKS World 2019 earlier this year, all these cloud-based solutions will be part of the 3DEXPERIENCE.WORKS portfolio.

“We aren’t just bringing powerful new capabilities to the SOLIDWORKS portfolio everybody knows and loves, but also extending it to the cloud through the 3DEXPERIENCE platform, the only holistic digital experience platform in the world. We’ve built a bridge to our platform-based portfolio, empowering our users to take advantage of 3DEXPERIENCE.WORKS offerings,” said Gian Paolo Bassi, CEO, SOLIDWORKS, Dassault Systèmes. “This gives organizations the environment and the applications to truly embrace the Industry Renaissance and its spirit of discovery for new ways of inventing, innovating, collaborating and producing.”

“Since 2002, Omax has used SOLIDWORKS applications to design every part of the fastest and most precise waterjet cutting technology in the industry,” said Eric A. Beatty, Senior Mechanical Designer, Omax Corporation. “Omax will continue to innovate and develop its waterjet machines and accessories with SOLIDWORKS 2020, which offers game-changing power, performance, and collaboration in the field by opening up access to the value creation process to everyone, everywhere, on any device.”
