Welcome to the DASSAULT SYSTÈMES User Conference in Hanau!

Here are some news from the Hanau Congress Park, where over 500 users of Dassault Systèmes solutions for CATIA, SIMULIA and SIMPACK have gathered. The Congress Park integrates the historic baroque royal stables of the Hanau Castle, which was rebuilt into a town hall, with a modern extension. This is a showcase of Dassault Systèmes solutions, as well as resellers and partners, who are busy visiting during breaks. Gold Sponsors are Cenit and Technia Transcat.

9:35 am: Philippe Laufer, CEO of CATIA, and David Holman, VP of SIMULIA R & D, will open the event with an overview of the 3DEXPERIENCE platform. The platform is - among other things - operating system and business model. The 3DEXPERIENCE now offers over 300 roles - these are function sets adapted to specific tasks - in the cloud.

Few CATIA Champions on stage @DSUC 2018, in Hanau Germany

The scene is set ... Transformation is there ...

Joby Aviation develops an electric, autonomous air taxi on the 3DEXPERIENCE platform. The cloud enables collaboration around the world without IT support.

ECAX Reference Model: Enterprise, Collaborative, Apps and Software as a Service. Enterprise means: Working with local software packages, Collaborative is the connection of these packages with the platform. If the packages are integrated into the platform, this is the apps category, after all, the packages go into the platform and are available everywhere and on any medium. With this model Dassault Systèmes classifies the digitization degree of companies in the implementation of solutions.

Laufer demonstrates how seamlessly the platform can be integrated into work with a locally installed CATIA V5. It only changes the handling of data, these are stored in the so-called POWER'By solution in the platform and called from there, instead of working with drives.

The separation between CAD and computational engineer is not a "God-given" separation, but arose because the tools were so complex that the specialists had to focus on one of the two disciplines. Today, that's changing as the tools become simpler and smarter. Holman now discusses the Simulia portfolio from design-accompanying to multi-body multi-discipline simulation.

Laufer: "We are evolving from CAD to CAD - from computer aided design to cognitive augmented design." The system supports the developer with modeling and generative design. You do not model the geometry, but the specifications and the desired function, the computer develops an optimal geometry based on these specifications.

An Industry Solution Experience consists of roles that in turn define function sets - all based on the 3DEXPERIENCE platform. The customer no longer buys fixed, extensive packages whose functionality requires only fractions, but tailor-made combinations that are tailored to the processes in the industry. The experience for the development of electric cars, for example, consists of nine industrial processes that contain functionalities from all areas of the platform.

Among other things, the industrial process for battery development includes simulation functions that map the chemical processes in the battery, but also mechanical and, above all, thermal simulations.

The 3DEXPERIENCE platform enables huge productivity gains.

The introduction of the 3DEXPERIENCE enables productivity increases of five to ten times. Laufer has some arguments to support this - but the load times of models are 7-10 times shorter, the geometry performance increases by 35 percent. 3D immersion fifths the necessary training times.

The speakers introduce the Champion Program and its first participants. The 65 participants are particularly active in the appropriate forums and get access to new versions, features and apps to test them.

11:00: After a short break, the big plenary hall continues with Olivier Ribet, EVP Global Field Operation EMEAR. He talks about the vision and strategy of Dassault Systèmes in cross industry initiatives. "Digitalization does not work when you connect email and data to a SharePoint server, you need a real platform."

Olivier Ribet talks about the visions surrounding the 3DEXPERIENCE.
He talks about different industries, first aerospace. The production figures of aircraft increase from 1415 in 2015 to 1816 in 2033, AM is rapidly gaining in importance, at the same time the regulatory requirements for aircraft, for example in the field of noise emission. Energy efficiency and new types of drive play an important role.

There are similar requirements in the area of ​​life sciences: faster innovation rates, the need for virtual tests, increasing regulation, the capitalization of knowledge and know-how, and personalized and precision medicine. Preoperative planning on 3D printed models of the individual patient's real organs, created directly from CT scans. This allows a very accurate planning of the operation before the first cut is made. This makes the surgeon's work easier and protects the patient.

High-Tech: A fingernail-sized chip has more subsystems than an airplane. Electronic devices will change completely if the circuits can be integrated directly into a piece of plastic.

Dassault Systèmes offers solutions to all these challenges, covering entire industries and uniting them in one platform. "From the atom to the city" reaches the scale of the solutions. Dassault invests heavily in research and interesting companies. "We are here for the long run."

11:38: It goes on with additives: Steven Ribeiro-Ayeh talks about "Print to Perform", the industry experience for additive manufacturing. The Experience consists of the apps Generative Design, Process Planning, Virtual Printing and Post Processing.

Dassault's AM Experience Print to Perform includes four apps.
Generative design can adapt geometry to manufacturing processes, such as milling or AM. Completely new is the possibility of generatively optimizing complete assemblies. Lattice / grid structures make it possible to generate extremely stiff and lightweight components.

Process Planning works with a digital twin of the 3D printer, which makes it possible to plan the construction process very accurately and realistically. Support structures can be created and changed interactively. This accurately predicts printing times and costs.

Virtual printing means exactly simulating the printing process. The app includes a process simulation architecture that generates realistic simulations of the printing process based on part geometry, material data, and digital twin of the machine. The mesh intersection tool generates optimal networks based on the slices for fast calculations. Even the free surface of the powder bed is taken into account in the heat distribution. In addition to the printing process, cracks are discovered and taken into account in the simulation in order to adapt the process and to be able to produce the remaining parts in a clean manner. Multi-laser systems can be simulated, as well as the HP MultiJet Fusion systems developed using Dassault Systèmes solutions.

The post processing app can simulate heat treatments and milling to remove parts from the build platform and supports. The remaining residual stresses and their resulting lifetime effects can also be analyzed.

Shape Compensation: The parts twist and bend in the heat treatment. This app makes it possible to "pre-shape" the CAD model so that the desired shape results after the heat treatment by the bending.

12:00: With a little delay, it's the lunch break. Afterwards parallel sessions will start, I will continue to report live the highlights from the many lectures by Dassault Systèmes, partners and customers.

David Holman and Eric Bienvenue with an executive summary on SIMULIA

13:30, Paul Hindemith Hall: Eric Bienvenue, VP of Worldwide Sales SIMULIA, gives an overview of Dassault Systèmes' simulation portfolio. He is supported by David Holman. The question is: how do we bring together previously separate silos modeling and design to create added value? Simulation is essential for the transformation.

Interesting comparison: When the electric motor replaced the steam engine, this initially resulted in no productivity boost in production, which came only 20 years later with the invention of the assembly line. New technology in itself is not enough, it needs a change of mindset.

Multibody simulation is just as out of the corner as multi-discipline simulation. Complex products can be organized with Model Based Systems Engineering, analyzing electromagnetics as well as acoustics.

Impressive algorithmic design on a design study by DS Automobile

14:05: It continues in the design track with Nicolas Deluy DS Automobiles. He shows a design study whose grid-like lighting concept should be implemented in real models of the DS series such as the DS7. In the DS3 Dark Side 3D-printed grid structures made of titanium were used for the first time. The structure, which derives from the DS logo, was created by parametric programming in Catia.

14:30, Brothers Grimm Hall: Nicolas Deluy is also part of a design roundtable on "The next Mobility Experience". Other participants are Taiki Furuki of Kubota and Gray Holland of UX-FLO. Furuki talks about smaller and smaller farm machinery working together. In Japanese, "co-design" means "living together". The customer is the target of all development efforts and is drafted into development processes.

 

Anne Asensio of Dassault Systèmes, who leads the conversation, says that we no longer design products, but product experiences. Gray Holland: "People do not really like change. Holland designed one of the first electric vehicles developed by GM around 40 years ago. He used the then very new stereolithography technology. Gray: The job of the designer is not to follow trends, but to set and support trends - to create experiences. In the process, brands are changing - they are no longer inaccessible "heroes", but rather a component of the customer.

Deluy: The designer becomes a hybrid that determines not only the design but also technologies and integrates into his work. Deluy: We're designers who need to learn more about the tools, more about the technology we've just packaged. Furuki: The changes in society must be incorporated into the design.

Holland is a consultant and helps companies build teams that implement modern technologies. Interestingly, he often experiences the resistance to change in the company more than between companies and customers. Asensio praises the three designers as prototypes of the new generation of designers, who have a new focus on their tools.

14:42: The designers are fast, almost 20 minutes ahead of time - Xavier Melkonian of Dassault Systèmes is pleased that he has more time to present the strategy & trends for CATIA Design. He sees it as essential that designers, System architects and designers work together seamlessly as the disciplines and their work grow together. In the past, the designer was primarily concerned with the outer shell, so today's design and function are increasingly merging - see the active surfaces in various concept cars, in which movement, functions or lighting conquer the surfaces of the vehicle.

 

That's why designers need to be able to work on the 3D model - at the same time as the designers. CATIA Natural Sketching allows drawing in 3D. It allows you to open 3D models on the Wacom tablet and draw on them. With Release 2019x Dassault Systèmes extends this to immersive design, which is used with the VR glasses. A colleague from Melkonian shows a fascinating VR design in which she designs a backpack on a 3D model of a human - simply by drawing in the air, she spans surfaces, positions and edits curves. Very impressive.

CATIA Imagine & Shape: At the heart of development are productivity gains, new features, and a consistent workflow across the various modeling technologies. Different curves - different in relation to the mathematics behind them - can be blended together and adapted to each other. An impressive video shows how the technology is used in Honda Power Products.

15:25, Conference room 5: Modeling an aerospace part in the additive / additive process with Andrés Bellés Meseguer of Prime Aerospace, an Austrian engineering service provider for the aerospace industry. The Prime designers developed a hinge for the service doors of the engines of the Airbus A340 neo. By optimizing with Abaqus / Tosca, a reduction of the weight to 25% of the original part could be achieved - with doubled stiffness!

In a second step, a workflow was developed to simplify this relatively complex process. A menu in 3DEXPERIENCE guides you through the process, which still requires a lot of engineering knowledge to achieve meaningful results. Depending on which constraints are defined, the result of the optimization changes very much, the designer must readjust a great deal - the proof that it is not far with the much-vaunted "artificial intelligence". The optimization algorithm does exactly what you put in it, regardless of whether the result makes sense. Nonetheless, the results are very impressive.

16:20, Landgraf Room: After the coffee break, we continue with a customer presentation from the SIMPACK area: BMW's Basem Abdelfattah and Dassault Systèmes' Magdalena Niedhammer talk about the analysis of chain drives in car engines. The timing chains of different engines were analyzed - as a model with all chain links.

Using the SIMPACK analysis, Abdelfattah was able to show that the well-known chain whining could be reduced by stiffening a bearing support. A revision of the SIMPACK solver in Release 2018x and 2019x enabled a reduction of the computing time to a quarter.

16:50: Carsten Schulz, CAE professor at Anhalt University of Applied Sciences, talks about "Maintenance Prediction using Real-time Digital Twins". The intention of the study was to calculate the true load of a gear instead of fixed maintenance intervals, and then perform the maintenance based on it, if it is really necessary.

Today's condition monitoring allows the documentation of the CV, but no real forecast about the future. By contrast, virtual condition monitoring - validated with real condition monitoring - makes it possible to predict the next 30-40 seconds and even influence a motor control in such a way that, for example, natural frequencies are avoided. With the help of a self-built gear this is currently being tested in real life, later experiments will follow at a commercial locomotive transmission.

17:10, Gebrüder Grimm-Saal B: "Concept Modeling @ Ford" with Axel Hänschke from the Ford Motor Company. The automaker has a four-stage development concept from the 1D function simulation to the detailed simulation and the transfer of the concept to the detailed design. So far, however, it has not been possible to play back the results of detailed design back into the concept phase, for example, for the development of a new vehicle generation. Hänschke hopes for the introduction of the 3DEXPERIENCE platform at Ford.

Hänschke talks about the mathematical capture and optimization of design spaces in the car. The necessary components such as wheels, drive, but also passengers and their fields of view are recorded and arranged in a Matlab-like language, the space in between is then the space for the vehicle structure in which, for example, with Generative Design an optimized structure can be defined.

Jaguar Land Rover's Tayeb Zeguer was unable to attend, so his lecture will be held by Nikolai Baumeister of Dassault Systèmes. It is about the connection of SFE with the 3DEXPERIENCE platform, concept modeling of bodies. Jaguar Land Rover has automated this process into parts on the 3DEXPERIENCE platform to optimize parts of the body using simulation. Among other things, positions of roof pillars and their cross-sections are optimized with respect to roof crash simulations.

JLR has implemented an interesting process that exemplifies the benefits of integrating modeling or geometry generation with simulation on a single platform. Safe at a high, complex level, but today's "takeaway" is that we should think a lot more about integrating the simulation into the design process. The advances in simulation tools as well as the emergence of platforms or integrated file formats make this much easier than it was years ago. The advantages and potential of this combination are certainly proven in practice and really amazingly large.

17:50: End of the sessions. This is followed by an evening event and we hope to see (or read) again tomorrow at 9:00 am. I wish a nice evening!

Thanks to Ralf Steck for his blogging.

Stay tune for next news from the event!
