Being a design and manu-facturing engineer in the automotive or aerospace industries today is a more challenging job than in the past! Changing regu-lations and the need to produce and deliver more environmentally friendly products, calls for chang-ing sheet gauge, mate-rial and/or geometry. It is now possible to meet the rapidly growing challenges by using Virtual Prototying.

Virtual Prototyping is a principal instrument in man-aging these challenges. For any given metal forming process, it is possible today to conceive everything in a virtual engineering equivalent – from detailing cus-tomer requests to virtually inspecting the final prod-uct, as well as setting-up the production facilities. This includes material cost estimation, die design and feasibility, part design validation, and tooling design and forming processes.

But we do not stop here! In the case of the hot forming process, engineers can validate the cooling capabilities of a die, merging the results of a thermo-mechanical sheet metal forming simulation into a conjugate heat transfer model. This delivers engineer-ing insight into pressure drops, coolant velocity, cool-ant temperature, heat transfer in the cooling channels, and die face temperatures. Finally, the function of the complete hot forming line including the physics of the part manufacturing process can be inspected in a virtual environment using 3D immersive Virtual Reality – all this way before any costly prototypes and manufacturing lines are built.

In our special report, we have chosen to demonstrate how our Chinese customers have achieved great suc-cesses through the use of ESI’s advanced manufactur-ing simulation tools. From the latest Centrifugal Cast-ing processes to Aluminum & Magnesium Die Casting and Super-Plastic Forming & Diffusion Bonding. Here we have selected a few technologies that we have seen emerge and become embedded across industry sectors.

Forming of high performance materials and use of new assembly techniques in the Aeronautic & Defense sector

Shenyang Aircraft Corporation, an entity in the Chinese national AVIC group, has managed to reduce the weight of parts in its new fighter jet structure. They achieved this by using state-of-the-art Superplastic Forming processes and Diffusion Bonding assembly techniques.

The advanced simulation capabilities of ESI’s sheet metal forming solution PAM-STAMP enabled Shenyang to leverage advanced manufacturing techniques to form parts made of high-performance TA15 titanium alloy. Thanks to simulation, they

successfully overcame the challenge of forming the titanium parts into the many intricate shapes the design required and achieved a substantial weight reduction.

Some challenging geometrical requirements were also met through the use of Superplastic Forming (SPF) and previously experienced thinning and local striction issues were eliminated by using PAM-STAMP.

To sustain the weight reduction achieved during the forming stage, Shenyang looked for an alternative to traditional assembly fasteners (such as riveting, screwing and adhesive joints) and ultimately turned to Diffusion Bonding (DB), a process that could also be modeled and controlled thanks to PAM-STAMP.

Implementing manufacturing simulation rapidly andefficiently,totacklecostlymanufacturingdefects

Taiwan based Zheng Yang Mould Manufactory has been producing dies for the High Pressure Die Castings of Aluminum & Magnesium alloys, supplying to the automotive, machinery & electronic industries since 1993. In order to achieve greater product complexity by means other than costly trial & error methods, they turned to simulation, selecting QuikCAST, ESI’s fast and efficient simulation solution for casting process evaluation.

By working with ESI’s local partner Elite Crown, Zheng Yang ensured they could gain not only a correct usage of the software

tool, but, more importantly, the right methodology. That way, they rapidly led Zheng Yang’s die designers, who had no significant experience in CAE software, to successfully adopt simulation within the frame of their traditional die design cycle and to save on development costs and time.

The Zheng Yang factory is now able to use advanced manufacturing simulation methods that enable them to anticipate and then correct filling and solidification defects, typically linked to air entrapment, surface defects and shrinkage porosity. They have now mastered the art of casting simulation coupled with thermal effects, so they can correctly account for the evolution of die temperatures and the effect on the viscosity of the molten metal. Thanks to QuikCAST, Zheng Yang now easily manages process and design modifications for the filling system, including runner profile and positioning, gate balancing, and placement of overflows.

All in all, Zheng Yang is a great example of how casting simulation software empowers small size companies to meet their customers’ needs for faster and better quality dies.

Centrifugal casting of large parts made of titanium alloys, for the Aerospace sector

Recently, an ESI team based in Switzerland has taken part in the sino-european research project focusing on the Casting of Large Titanium Structures (COLTS). Funded by the European Commission within its Seventh Framework Programme, the project combined technical knowledge already available in Europe with the considerable industrial experience of centrifugal and gravity casting of components up to 1.5m in length that exists in China.

The COLTS project also included development of a comprehensive database of the mechanical properties of Ti6Al4V, which is the most common titanium alloy used in aerospace applications.

Through the project, ESI built and applied modeling capabilities to accurately predict and control the essential aspects of each technical process involved. In order to achieve this, ESI extended the capabilities of ProCAST; improving its fluid-flow solver to handle complex turbulent flow patterns and include the effect of the direction of the centrifugal force on porosity formation.

ESI’s casting simulation software needed to enable the early prediction of potential problems such as filling-related defects (inclusions, misruns, blowholes…), porosity formed during solidification, and deformation during subsequent cooling. This had to be done in such a way that the effect of process parameters (including filling time, filling temperature, mold pre-heating temperature, and mold rotation speed) could be readily assessed.

The COLTS project has contributed to the rapid development of cost-efficient manufacturing techniques for titanium parts used in the aeronautic sector and thus reinforced the competitiveness of both Europe and China in that sector, while strengthening strategic international cooperation between the two regions.

The deformation (right) observed in the cross beams of the cubic shaped frame are in good agreement with the predicted results (left).


“The extended functionalities of ProCAST,

gained through the COLTS project, will be

invaluable at industrial level to set up cost-

efficient centrifugal casting processes for tita-

nium parts. Manufacturers using the software

will gain a considerable amount of time and

money, contributing to the production of

better quality parts for aeronautical applica-

tions, both in Europe and in China.”

Dr Rui Yang, Director from the Institute of Metal Research in

China, who participated in the COLTS project.

“If time and cost weren’t constraints,

we could solve many issues without

simulation. Thanks to ESI’s QuikCAST

casting simulation software, we can test

and improve our designs, while building

our internal expertise relative to various

scenarios unseen before.”

What trends do you observe in China’s manufacturing industry today?

“Improving quality and protecting the environment, through lower energy consumption and CO2 emissions, are the main priorities for the Chinese government and local manufacturers today.Theseprioritiesdrivetheirspecific interest ingreenmanufacturing and intelligent manufacturing technologies.

In the past few years, Chinese Research and Development, as well as manufacturing capabilities, have grown and enabled us to face global competition in terms of innovation. For example, the performance of high-speed trains has greatly improved during the past years – achieving greater speed, comfort, and reliability, along with lower noise and production cost.

Our automotive industry, restructured and streamlined, is now equipped to address global markets: through numerous mergers and acquisitions, our automotive industry has been reduced from hundreds of manufacturers to a handful of world-class OEMs.

New materials and new technologies are constantly being developed. China’s ability for innovation has been enhanced. Design and manufacturing are being integrated... Many of these recent advances are directly linked to simulation: using CAE to support development of advanced manufacturing and to open new perspectives that will bring economic welfare and increased social value. Our team at ESI China is proud to contribute to the country’s socio-economic progress.”

Grace Cui,COO of ESI China.

4 questions to Grace Cui, COO of ESI China

In what areas of manufacturing is China becoming one of the world leaders?

“The scale and production capacity of the Chinese manufacturing industry have helped China become the largest manufacturing country in the world, ahead of the U.S. since 2010. Leader in terms of volume, China has also developed numerous new materials and technologies. But from my point of view, we still have a long way to go in order to catch up in terms of technical leadership.

I think China is in a good position to deliver world-class innovations for casting processes (especially for precision casting and large parts), for mold design and manufacturing (especially for precision molding in the automotive sector), composite material processes, and 3D printing. From an industry perspective, China excels in developing innovative processes for rail and heavy machinery.”

The automotive industry worldwide continually faces great challenges in product and process development. Due to the increasing number of models and variants, the market demands shorter and shorter development cycles. As a result, the use of virtual engineering and virtual technologies is becoming increasingly necessary in product development to support styling, engineering and production.

To be able to face these challenges, Ford decided to invest in technological innovation and to integrate ESI’s Virtual Reality solution IC.IDO in its Product Development Processes. Today, Ford has five IC.IDO Virtual Reality installations in Europe and in the United States. In Cologne, Germany, Ford’s team uses the sys tem to manage product development and engineering.

With ESI’s PAM-RTM, we now have a tool and a methodology to predict and correct all possible defects occurring during the injection process; starting at the beginning of the design of the mold, before any physical trial.

Federico Martin de la Escalera, Head of Research and Technology Dept.,

Aernnova Engineering Solutions Iberica.

Aernnova is a Spanish aerostructures company which takes on the integral design and manufacture of large aircraft sections for customers worldwide. In the past they have successfully produced composite aircraft components by manual draping of preimpregnated fibers (prepregs) and curing in an autoclave. Unfortunately when their engineers tried for the first time to apply a Resin Transfer Molding (RTM) process to two Airbus A350 XWB parts – the bearing rib and the leading edge of the horizontal stabilizer – their experience proved to be not directly transferable. Performance expectations of such critical parts are high, and manufacturing defects such as wrinkles, excessive shearing in the preform or porosity levels had to be managed within strict tolerance levels.

Aernnova made a video recording of the injection process and confirmed the accuracy of the PAM-RTM filling simulation when taking into account the draping effect. These impressive correlations led Aernnova to gain high confidence in simulation results. Consequently, and at little cost, they modified the leading edge mold and achieved a much higher part quality.

and defined the injection strategy (injection pressure, location of vents, and injection gates and channels). They immediately spotted wrinkles in the preforms originating from the manual draping process. They were able to remove these by applying manual pressure on the preform.

Additional issues were encountered during the injection process. In spite of several costly and time consuming trials to determine the optimum injection strategy, the team still observed dry spots that would affect the mechanical performance of these structural parts.

Predicting the shearing of the preform

Simulations using PAM-RTM also demonstrated the importance of the shearing of the preform on the accuracy of prediction of resin flow during injection.

Aernnova’s engineers simulated the preforming stage using ESI’s composites forming application, PAM-FORM, to predict the fiber angle in the preform and used these results in the PAM-

RTM setup. The permeability of a preform could be defined as a function of the shear angle in PAM-RTM, consequent ly improving the p r e d i c t i o n of resin f low p at t e r n a n d filling time.

ESI takes part in a European biomedical project led by the UniversityofSheffieldtohelpdiagnose dementia

c u s t o m e r s u c c e s s b i o m e d i c a l

Virtual Prototyping improves our daily lives by application in multiple industry sectors – from automotive to nuclear, aeronautics or electronics. ESI solutions can also be applied to biomedicine, and more specifically to support the early diagnosis of dementia, thus improving the patient’s quality of life.

Today roughly 36 million individuals in Europe are suffering from dementia. It is expected that this number will increase to 115 million by 2050, due to the ageing population. The consequent annual cost is estimated at €55B in Europe and €450B worldwide (1% of the World Gross Domestic Product). In 2012, the World Health Organization declared dementia a global health priority, highlighting the urgent need for improvements in treatment.

Providing multi-scale modeling of cerebral fluid transport with ACE+ Simulation Suite

From the European Initiative on Alzheimer’s disease and other dementias in 2011 to the G8 Dementia Summit in 2013 , and choice of 2014 as the Year of the Brain by the European Brain Council (EBC) , nations around the wor ld show a new impulse to spur improvements in brain health. The EBC’s Manifesto highlights that the complexity of the brain requires an interdiscipl inary approach . In th i s context, the European Commission initiated

the VPH-DARE@IT project (Virtual Physiological Human: DementiA Research Enabled by IT), co-funded by a number of industrial stakeholders.

A four year and €18 million project, VPH-DARE@IT will use computational methods to discover new biomarkers of dementia. The project will deliver the first image-based patient-specific predictive models for early differential diagnosis of dementias and their evolution. Project partners, including ESI, aim to create the first personalized, multi-factorial model of brain structure and function including biophysical and metabolic knowledge. This project will be the first to combine a wide range of physiological data from medical imaging – such as blood flow, brain tissue properties and

cellular activity – with psychological measures such as memory and cognitive function. It will also bring in demographic, genetic, lifestyle and environmental factors, making it much more sensitive than existing diagnostic tools.

As part of this project, ESI will extend its computational fluid dynamics solution ACE+ Suite to model complex poroelastic phenomena in combination with multiple brain fluids. Using ACE+, scientists will be able to better understand the advanced fluid structure interactions taking place in different brain tissues. Researchers will also be able to see the implications of factors such as pulsating blood flow, or the increase of cerebral liquid. Models will then be personalized depending on factors such as age or tissue rigidity.

Today roughly 36 million individuals in Europe are suffering from dementia. It is expected that this number will increase to 115 million by 2050, due to the ageing population.

German manufacturer EUROS manages the production of 80 meter long composite rotor blades using simulation

c u s t o m e r s u c c e s s w i n d e n e r g y

Founded in Berlin in 1996, EUROS is expert in the field of manufacturing wind turbine rotor blades for customers around the world. From its German development office, EUROS carries out all tasks connected with rotor blade design - starting with the concept and design phase, through model and mold building, prototyping, certification, up to serial production using hand lamination and vacuum infusion technology. EUROS customers select blades from the existing range of products or ask to modify available blades according to their requirements.

As current industry trends require increasingly longer and larger blades, one of EUROS’ customers asked for an 80 meter long wind turbine rotor blade. EUROS set to develop an optimum manufacturing process that would achieve high quality and high strength for a blade of this dimension. They customarily use a specific manufacturing process called Vacuum Assisted Resin Infusion (VARI) and note that the downside of this process is that it often requires many costly and time-consuming trials to achieve the desired quality.

EUROS gains a better understanding of the resin infusion process

and the influence of different process parameters on product quality

To avoid this pitfall, EUROS decided to use ESI’s PAM-RTM simulation suite, enabling them to minimize risk while ensuring product quality, reducing manufacturing time and assuring process repeatability.

Validating process parameters on small samples with PAM-RTM

To achieve this, they followed a step-by-step approach. First, they determined key input data for the simulation by measuring in-plane and through-the-thickness permeability of all the glass fabrics used in the root – an area of the blade which plays a key structural role. Then, they validated measured permeability values and calibrated process parameters (such as pressure and viscosity) on small infusion models and compared with experimental results. EUROS was able to achieve good similarity between predicted and experimental resin flow patterns and filling times.

Full scale tests with PAM-RTM

EUROS then built a representative test mold (4.3 meters outer diameter) and used it together with PAM-RTM to validate their infusion strategy. The first simulation of a one shot infusion on a stack of 130 plies conformed to reality.

During a whole year, EUROS conducted additional tests on critical segments from the first 20 meters of the blade using the same methodology described above. These pre-trials on representative samples of the root of the rotor blade allowed EUROS to validate their numerical models by comparing simulation and experimental results. PAM-RTM simulation also contributed to building a better understanding of the parameters influencing the process, and allowed the virtual

testing of multiple process variations in order to retain only the optimal ones.

Thanks to PAM-RTM, EUROS was able to evaluate upfront several process alternatives with varying parameters in order to get the best results in terms of product quality, filling time, and process repeatability.

Early in the second quarter of 2013, EUROS built the first blade, 81.6 meters long and weighing 32.8 tons. They reached all of their pre-defined goals for product quality, infusion time, resin consumption and repeatability of the process.

Architecture of the CSDL demonstrator

Renault achieves complex part design collaboratively, using Vdot™

c u s t o m e r s u c c e s sa u t o m o t i v e

This case showed that we could successfully optimize iteration loops based on multidisciplinary criteria to produce better engine design, with the help of Vdot™ (ESI’s lean process management solution), Alternova (Renault’s optimizer), and centralized computing services. Rolling out this methodology will enable us to reduce both time and design costs, while improving the performance of our engines.

Christian Fourcade, Research Engineer, Renault

Along with ESI and several third-party software suppliers, French car manufacturer Renault took part in the Complex Systems Design Lab (CSDL) project, an €18 Million R&D project led by competitiveness cluster Pole Systematic. The objective of the project, partly funded by the French government, was to address issues linked to concurrent engineering and multi-domain optimization. Through this project, Renault was looking for solutions that could be applied early in vehicle development programs for maximum impact on cost efficiency.

Renault supplied a case to the CSDL team: the design optimization of a gas engine, with the aim to maximize its lifetime. This example was well suited to evaluating the capacity of current systems to perform optimization campaigns for rather complex 3D parts.

Renault was particularly interested in the collaborative aspects of the workflow platform and the interoperability of CAD & CAE engineering applications. Two workflows were modeled and executed in Vdot™, ESI’s lean process management solution:

· An optimization process aimed at minimizing the thermal gradient between the intake and exhaust valve bodies, thus reducing the risk of fatigue induced fracture;

· A multidisciplinary simulation process to validate the resulting optimum design through a comprehensive analysis of the engine, including its manufacturing aspects.

All software was installed centrally on an HPC cluster and in Software As A Service (SAAS) mode, so team members could work remotely on laptops. The optimization workflow developed in Vdot™ invoked third-party optimization tools as well as CFD thermal and mechanical simulation workflows.

The orchestration of multidisciplinary simulation processes in a

homogeneous environment enabled an efficient collaboration between design teams

As a result, the definition of the new virtual tests, related simulations and the creation of response models ran in batch mode, and Renault teams could analyze optimization results and interactively make decisions at the end of each iteration cycle.

The second workflow demonstrated the capacity of Vdot™ to orchestrate a complex multi-physics design process, allowing independent tasks to run in parallel (casting and CFD thermal simulations) while downstream tasks (mechanical simulations) were set-up to start computing as soon as results were available. Vdot™ also ensured that engineers were notified when a job was completed, and ensured they were working with the right data in the right applications. The teams could track progress using management dashboards.

Pharmaceutical machinery leader Bausch + Stroebel uses Virtual Reality to gainefficiencyinengineeringprocesses

IC.IDO allows them to predict usability

issues early in the development process

German company Bausch + Stroebel, world leader in pharmaceutical packaging machinery, has recently implemented Virtual Reality solution as part of its engineering processes. This deployment illustrates the ability of Virtual Reality to help industrial clients accelerate product development processes. It also demonstrates that Virtual Reality, now widely used by large companies in the automotive and aerospace sectors, can also be successfully implemented within smaller businesses in diverse industries, including the pharmaceutical domain.

A midsize business, Bausch + Stroebel serves some of the world’s largest pharmaceutical companies. They aim to deliver packaging machines that provide the highest possible standard of precision, while offering the best production rates, and complying with exceptionally demanding industry regulations. They have customized their offer to match often complex customer demand and today, they individually design each machine produced for specific operations, including decontamination, cleaning, sterilizing, filling, closing, inspection, and many more.

Looking for solutions to gain efficiency in their engineering processes, Bausch + Stroebel have sought to find an alternative to the wooden full-size prototypes formerly required to assess assembly aspects and reachability for their machines. Today, they have invested in Virtual Reality to enable their engineers to immerse themselves in a 3D environment in which they can interact in real-time with a life-size CAD model.

Using IC.IDO, ESI’s Virtual Reality solution, engineers can simulate assembly & disassembly sequences of their machines, check the reachability of control elements, operate design reviews and predict possible ergonomic issues. Bausch + Stroebel have also identified the potential of Virtual Reality to share current and future models with their clients in an interactive way. This minimizes the risk of misunderstanding at an early stage and assures that developments can be comprehended by everyone - not only the technical staff. According to a recent survey by Bausch + Stroebel, 98% of their clients consider that Virtual Reality is an improvement compared to

the previous CAD and wooden mock-ups they used to work from.

By choosing the portable Virtual Reality system IC.Road, Bausch + Stroebel is also able to use this technology to demonstrate their products at trade shows. The system can be set-up in 45 minutes and provides an interactive environment to showcase existing and upcoming machines to potential clients.

for more information: www.esi-group.com/VPS

p r o d u c t n e w s

Using a common core model for their simulations, engineering teams from various departments and from different geographical sites can now collaborate efficiently towards the creation of virtual prototypes that can be used to predict the behavior of parts or products in all domains of performance.

Aside from delivering faster results for crash simulation, the new version also offers new approaches for modeling product assembly, for assessing Noise, Vibration & Harshness (NVH), and for predicting airbag opening behavior more accurately. Virtual Performance Solution

brings industrial clients a decisive competitive advantage, especially when facing the numerous challenges introduced by lightweight engineering; including the need for numerous design iterations, for trade-offs between performance domains, and for managing safety margins.

Depending on the industry, domains of application may include structural stiffness and strength, crash, occupant safety, NVH & interior acoustics, comfort, durability, and high velocity impact.

Thanks to a new execution scheme that supports Multi-Model Coupling, the new version of Virtual Performance Solution is simpler to set-up, offers easier task submission, and delivers significantly faster calculations. Distributed Memory Processing (DMP) has been complemented by an alternating job execution per model, reducing processing time by 20 to 30%.

This latest version also offers a new approach

for modeling adhesive bonding by introducing

special 3D connection elements.

The Finite Pointset Method (FPM) module

now includes turbulence models for gas flow,

enabling increased precision in the simulation

of even the most complex airbag systems;

notably curtain airbags.

The latest version of Virtual Performance

Solution also comes with improvements for

NVH assessment. A new method to evaluate

Random Response enables vehicle engineers to

achieve a more consistent vehicle by providing

more precise prediction of how different

road loads and other conditions influence the

performance of parts or products. Furthermore,

a new scheme for non-linear transient implicit

calculations is added to improve the accuracy

of durability and strength predictions.

Acquisition of CyDesign Labs. Inc., a lead innovator in Systems Modeling

In October 2013, ESI acquired CyDesign Labs, a US company based in the Silicon Valley that owns a disruptive proprietary technology for advanced product design. Aligned with ESI’s proven strategy that fosters the gradual elimination of physical prototypes, this acquisition brings a major technology leap to accelerate industrial product and process development.

Founded in 2011 as a start-up company, CyDesign, was awarded a significant contract in early 2012 by the United States Defense Advanced Research Projects Agency (DARPA) to support the Fast, Adaptable, Next-Generation Ground Vehicle (FANG) Challenge. In 2013, CyDesign successfully delivered a cloud-based systems modeling platform for use by FANG Challenge registrants.

CyDesign Labs core capabilities enable an organization to address a series of design challenges of increasing complexity, while leveraging fab-less design, foundry-style manufacturing, and crowd-sourced innovation models to control in real time manufactured products from their very first digital models. This provides designers using simple 0D-1D models with the possibility of validating collaboratively, online, the compliance of a product - as a system or as one of its components right from the beginning of design - with respect to environmental, safety, comfort, and other multiple performance requirements and technical standards. When the solution from CyDesign Labs is combined with ESI solutions it is possible for designers to connect ‘live’ with the 3D models of CAE engineers.

This evolution will allow ESI Group to provide its customers with a more comprehensive offering that covers the entire value chain of a product: from inception to verification, validation and certification. This extension of

ESI Group’s past focus on validation positions the company higher in the product value chain and is expected to stimulate the interest of players who are either seeking to or are currently migrating towards End-to-End Virtual Prototyping.

“This acquisition is poised to allow ESI Group to expand its user base to all players involved in creating industrial products – adding a seamless collaborative environment between specifiers, inception designers, and validation engineers. CyDesign Labs’ collaboration with DARPA has proven the relevance of combining 0D-1D simple design tools with traditional advanced 3D simulation. This operation represents a unique opportunity for ESI to leapfrog and actively contribute to the grand challenge of the 4th industrial revolution,” says Alain de Rouvray, ESI Group’s Chairman and CEO.

CyDesign solutions provide simulation data to derive the best design choices before CAD.

Creation of the Chair “Centrale Nantes – ESI”

Acquisition of the Vietnamese company CAMMECH

On January 21, 2014, in Nantes, Ecole Centrale

Nantes and ESI launched a 6-year joint

research program for which an Endowed Chair

was created. Both organizations will conduct

advanced research on the topics of Model

Reduction, Advanced Welding Simulation, and

Thermoplastic Welding.

The research scope has been designed to solve

current and future problems linked to advanced

multi-material design and optimization

strategies. Pr. Francisco Chinesta, Professor of

Computational Mechanics at Centrale Nantes

(France) and titular of the EADS Foundation

Chair for the past four years, has been

appointed “Centrale Nantes – ESI Chair”.

In February 2014, ESI acquired the Vietnamese

company Cam Mechanical Solutions Co., Ltd,

(CAMMECH). This facilitates the creation in

Asia of a ‘near-shore’ services division that will

be dedicated to the execution of high value-

added projects.

Based in Hô-Chi-Minh city, CAMMECH

employs a team of 10 highly qualified engineers

who will serve as a foundation for further

expansion in Computer-Aided Engineering

(CAE). The acquisition brings to ESI an enhanced

understanding of the Vietnamese market and,

in that context, the expertise of a local and

highly competent partner fully operational

and with a skilled management team. Notably

ESI has acquired a platform that facilitates the

recruitment of experienced engineers, ready to

operate immediately.

For Model Reduction Strategies, both

organizations wil l work towards the

development of virtual charts for non-linear

models involving multiple parameters, by

using the Proper Generalized Decomposition

(PGD method). These virtual charts represent

complex mathematical relationships at a

glance, e.g. in the form of tables that can be

easily visualized. They will be integrated in ESI

software to deliver real time simulation results,

optimization, and reverse analysis, with the

aim to predict even faster how design and

manufacturing changes (geometries, materials,

processes) will affect a finished product’s

performance.

For Advanced Welding Simulation, research will investigate Friction Stir Welding (FSW) processes, which enable the joining of dissimilar materials (such as steel and aluminum) in solid state. Another research objective will be to improve modeling techniques for additive manufacturing, as part of the welding process.

A research team will investigate out-of-autoclave systems based on thermoplastic materials, by focusing on the advanced simulation of automatic tape placement.

Lech Tomasz KISIELEWICZ, Executive Vice-President for ESI Services Operations, comments:

“The acquisition of the CAMMECH company allows the extension of our multi-shore coverage in Asia and the opening of a new center of competency close to our customers on this continent. Through this new foothold

we will meet the growth in demand for our services both on local and continental markets, and more specifically in Japan and South Korea.

We are also pleased to welcome a new highly experienced team on which we can count to support the Group’s development in Asia and around services dedicated to high value-added projects.”

2013 annual sales totalled €109.3 million, up 6.6% at constant currency and stable in actual terms. The currency effect, essentially a result of the negative evolution of the euro/yen parity, had an impact of -€7.0 million (-6.4%) on 2013 sales.

Activity in BRIC countries grew further, in line with the Group’s strategy of accompanying industrialists in emerging regions demonstrating economic potential. These countries accounted for 15.4% of total sales over the period, compared with 13.1% in 2012 and giving buoyant growth of +17.9%.

Amplificationofstrategicpartnershipsandsignificantincreaseintheadoption of end-to-end virtual prototyping

The signing in May 2013 of a strategic cooperation agreement with the Renault group marked for that company an intensification of the deployment of end-to-end virtual prototyping and illustrated the imperative of manufacturing industries to possess disruptive technology. Consequent to that agreement we signed in January 2014 three-year contracts covering the services to be undertaken for Renault, its subsidiaries, and Nissan Motor. Similarly, the Volkswagen group has also reiterated its confidence in ESI Group by signing and extending for the eighth consecutive time its 3-year contract; this time with a broader scope.

Like the automotive segment, the aeronautical and defence sectors, which are also subject to substantial competitive pressure and increasingly stringent environmental constraints, are highlighting the value added by ESI Group’s methodological and technological approach. EADS has launched further co-creation projects in the fields of vibro-acoustics, composites and assembly. Also in the aeronautical sector, ESI Group has recorded substantial growth of business with AVIC in China; a reflection of AVIC’s commitment to adopt ESI solutions even before the AVIC-ESI Joint Venture became effective on February 1, 2014. In the energy sector, AREVA signed a two-year engineering contract in line with its strategic plan aimed at strengthening its technological competitiveness, improving its economic performance and consolidating its nuclear security and safety policy.

The buoyant development of these strategic partnerships presages a more global deployment of virtual prototyping in all industries in the medium term.

Substantial improvement in operating profitabilityatconstantcurrency

In actual terms, EBITDA was up +8.5% to 9.6 million euros, giving a margin of 8.7% in 2013 compared with 8.1% in 2012. When reported at constant currency, the increase was even greater: +44.7% for an equivalent of 12.7 million euros, or a margin of 11.0%. These margins confirm the improvement in profitability that was visible over the second half of the year.
