Originally, Virtual Engineering was developed to address tech-nical issues in industries where physical testing was not feasible (due to safety, cost or size limita-tions for instance). It first aimed to deliver answers to critical challenges such as vulnerability in the defense sector, or safety issues for nuclear power plants.

Virtual Engineering practices then migrated to the automo-tive sector where they became the industry’s favorite method to address the new crash testing and passenger safety requirements, introduced in the early 90’s.

Moving forward, Simulation-Based Design has progressively gained the technical ability to allow for Virtual Prototyping, which has since proven to be an indispensable, mainstream technology to support engineering decisions at each and every stage of the Product Lifecycle Management process. It aids in assessment of product performance across many engineering domains and in evaluation of the product interaction with its environment. It can even be used to simulate the actual cus-tomer experience with the end product…

Virtual Prototyping increasingly includes manufacturing per-spectives, by addressing early in the product lifecycle how manufacturing will influence product performance and cost. Complementing this simulation capability, virtual prototyping now includes Virtual Reality solutions that can enable whole teams to interact naturally with their product in immersive 3D visualization. Virtual Prototyping helps industrial clients make the right decisions at the right time and, in some cases, reach product pre-certification without any physical testing.

ESI’s Virtual Prototyping software and services, widely used across many different industries with proven benefits, are increasingly relevant to the aeronautic sector – an industry with strong market demand but facing economic pressure due to fuel prices and the challenge of tightening regulations aimed at the reduction of Greenhouse Gas Emissions and noise, or safety regulations among others. Such requirements call for not only incremental, but also drastic weight reduction and improve-ments in engine performance and are driving the development and evolution of new and existing materials.

How will new materials, such as composites, impact product performance and its integrity? What best practices should be used to achieve optimal maintenance cycle and cost? Which processes will be the right ones when recycling requirements must be considered? Through co-creation with industry part-ners, ESI’s Virtual Prototyping can deliver adequate answers by taking into account each and every step of the product engi-neering process, and brings reliable and efficient support for engineering changes through a complex supply chain.

Reaching for the skies

s p e c i a l r e p o r t a e r o n a u t i c s

In the beginning...‘Reaching for the skies’ has always been the dream of mankind. In the ancient Greek mythology Icarus and Daedalus attached wax wings to their arms in order to escape from the island of Crete. It took three millenniums to move from “dream” to “reality” when Orville and Wilbur Wright achieved the first sustained flight on December 17, 1903. Only 60 years later, commercial transportation was revolutionized by an aircraft with a fuselage longer than the distance the Wright brothers flew that day, the Boeing 747 “Jumbo Jet”. Another 3 years later, Neil Armstrong set foot on the moon… Such astonishing breakthrough had never been attained in so little time in the history of engineering.

Computer simulation and aeronauticsThe contribution of Aeronautics to the field of Engineering (and in everyday life) has been immense. It is solely responsible for the origins of many computer methods engineers use today, whether related to Solid or Fluid Mechanics. Indeed the Finite Element Method was invented to gain a detailed and accurate understanding of the structural strength of an aircraft. The pioneers, Dr Turner (Boeing) and Professor Argyris (Department of Aeronautics, Imperial College) independently created the foundations of the Matrix Methods of Structural Analysis which were soon transformed by Professor Taig (British Electric Aircraft Corporation) and Professor Irons (Rolls Royce) to the Isoparametric Finite Element Method. At the same time, John Barlow (Rolls Royce) consolidated the practice of Gaussian Integration, while Professor Mark Wilkins (Lawrence Livermore Lab) rationalized the computational transient dynamics and shock wave propagation with the historic code HEMP ; the pillar of all transient dynamics codes of today, including ESI’s solvers. The rest is history, one involving much international contribution. Isoparametric Finite Element quadrilaterals

New challengesWith the aeronautic designs of the 60s (like forward-swept wings) soon surfaced needs that metallic structures could not meet. Filamentary composite materials (in particular Carbon Fiber Reinforced Plastics) were introduced as a potential alternative. It took more than 30 years for them to evolve to the point that they could be used within secondary members in aircraft construction. However, with the arrival of the new millennium, and the anticipated exponential growth of passenger numbers, stringent environmental constraints were imposed on the Aeronautics industry regarding exhaust and noise pollution. These translate into requirements for significant aircraft weight and aerodynamic drag reduction. Today, these same requirements precipitate the need for a sharp change in aircraft design, construction and associated materials usage.

New materialsComposite materials are at the forefront of aircraft technology and are now considered as candidates for primary structural members.

This is a game-changer! Traditional design methods no longer apply; the manufacture of these new low weight and high strength materials (which are in fact “mini-structures” by themselves) has to be an integral part of the design process. Detailed simulations of both manufacture and design phases are now compulsory. Multiphysics simulations become a “must” as structural, aero-elastic, thermal and electromagnetic disciplines interact in the Vulnerability Assessment of the aircraft. Since working on real scale models would be complex in aviation, suitable local-to-global approaches remain cornerstones of the design process. Physical testing becomes prohibitively expensive if not impossible, thus certification procedures have to evolve rapidly towards certification-by-simulation.

ESI: a partner to the aeronautics sectorESI Group has been a partner to the aeronautics / aerospace industry through the past 30 years of challenging transformation, either via direct industrial collaboration or via state sponsored R&D projects (government or EU). Recently, ESI has signed a 5 years strategic R&D partnership with AVIC ; supplied best in class solutions that help the US NASA with Virtual Mission Simulation (read our report, p.10) ; and provided tools for composite parts research to organizations such as LTDS (read more p.11).

For ESI, industrial partnerships have been acting as a catalyst for cross-fertilization of simulation technology across different industries, in particular between the Aeronautics and Automotive industries, as they share similar problematics. For instance, ESI’s Virtual Performance Solution has emerged from this collaboration (find out more p.18). It has enabled collaborative virtual prototyping methods, allowing multiple domains to be addressed using a Single Core Model, supported by pertinent physically correct models, powerful optimization algorithms for robust design, and industrially focused High Performance Computing (HPC) approaches like Multi-Model Coupling.

Virtual prototyping involving multiple domains is the sole credible answer for solving technical challenges in the Aeronautics of today and tomorrow.

Could you please explain what is the risk involved in using a mobile phone on a plane as opposed to

using other electronic devices?

“Airplanes are primarily made of aluminum, an excellent conductor of electricity. When an airplane is struck by lightning, electrical energy travels through its external metallic skin and is dissipated through the static wicks attached to the trailing edges of the wings. Burn marks can generally be found at the entry and exit points of the strike. In very severe conditions, electrical equipment or avionics may be slightly damaged. Conductive properties of aluminum enable the formation of a shielding “Faraday cage” around the airplane, protecting its contents from the high intensity currents that might flow along the outer structure of the aircraft towards the static wicks.

In contrast, if the radiating electricity source is located inside the aircraft, as it would be if passengers were using mobile phones, the shielding effect would strengthen the spurious parasitic signal generated by those devices. This signal would be conveyed to electronic equipment and to the aircraft avionics through the internal wiring. With the 100,000 electrical links of the brand new Airbus A380, featuring more than 300 miles of wiring (500 kilometers), you can easily imagine that Electromagnetic Interferences are generated!

Surprisingly, some airlines are now offering Wi-Fi connection onboard. So how are Wi-Fi networks different from mobile signals? Although featuring various radio frequency transmitters, Wi-Fi networks are operating with highly secured IEEE protocols (a trademark of the Wi-Fi Alliance) providing high quality worldwide interoperability. The immunity of the aircraft systems is thus easy to implement – much easier than with cell phones, which differ from most Portable Electronic Devices (PED) by sending out signals strong enough to be received at distances far away from the user.”

Can ESI software predict such electromagnetic compatibility issues and how?

“Experimental measurements are quite difficult to handle and very expensive to conduct with full size aircraft. On the other hand, ground testing may be quite different from real in-flight conditions - hence the need for simulation.

With Electro-Magnetic Compatibility and Interference issues (EMC/EMI), the situation is made complex by the internal wiring. The objective of

Jean-Claude Kedzia

Electromagnetics Product Manager,

ESI Group

3 questions for…

Numerical EMC applications is to identify risks and define favored coupling paths that allow the electromagnetic signals to interfere with sensitive onboard devices. Codes such as CRIPTE, initially developed by ONERA (the French Aerospace Laboratory) and now integrated within PAM-CEM, ESI’s Electomagnetic Simulation Suite for virtual testing, address the management of such cable networks and related induced phenomena. This software has been complemented with other 3D products in order to make it as predictive as possible. PAM-CEM’s reliability and efficiency have been demonstrated in a definite manner in the automotive sector, where internal wiring can also be impressive, as harnesses can comprise thousands of cables and wires.”

What improvements to PAM-CEM Simulation Suite do you foresee in the future? How would these be specifically beneficial to the aeronautics industry?

“Electromagnetic phenomena feature numerous and diversified mechanisms, spreading over a very wide frequency spectrum: ranging from direct currency with electrostatics, lightning or EMC/EMI and Radio Frequency communications in the low and medium bands, and up to several GigaHertz with arrays and radar devices. The electromagnetic radiation of an electronic device onboard an aircraft that includes 500 kilometers of wiring can definitely be seen as a multi-scale problem. The PAM-CEM Simulation Suite already includes several dedicated solutions for 3D radiation or induced effects, along with wiring using the CRIPTE code. In the 2011 version, ESI’s electromagnetic simulation suite has been reinforced with new tools, new modeling techniques, and new coupling procedures.

Another improvement axis is related to new materials. Together with the computation of near radiated electromagnetic fields up to 24 GHz and beyond, one major PAM-CEM feature released last year addressed the modeling of very thin metalized paint coatings on plastic bumpers (the success story with MAZDA is available in ESI talk 40, pages 8 and 9).

The newly released 2011 PAM-CEM Simulation Suite enables the investigation of 3D anisotropic materials. Improvements related to dispersive layered coatings will follow closely prior to the addition of composite materials management – a must for the aeronautics sector.”

Audi saves cost and development time with virtual airbag prototyping

Audi and ESI have been working together for many years on vehicle safety simulation. Recently, we have tackled the simulation of Out of Position (OoP) situations, in order to address the Federal Motor Vehicle Safety Standards FMVSS* 208 regulation.

Recent simulations use a number of different child dummies. For each dummy model, two positions must be tested: with the dummy standing in front of the dashboard and another with the dummy seated in front of it.

These simulations help Audi evaluate the physical phenomena of the airbag deployment with the objective of avoiding injuries related to deployment itself. Audi can optimize the airbag folding pattern early in the development cycle of new vehicles, saving time and cost. Audi engineers perform the complete airbag process in simulation, including folding, assembly and deployment using ESI solvers.

In the past, it took a week to model and run a new folding pattern for curtain and driver side airbags. To speed up the OoP simulation cycle, Audi developed an integrated CAE method and their engineers now use Sim-Folder, ESI’s airbag folding tool, to efficiently model folded airbags. Sim-Folder helps speed up the different phases of designing occupant restraint systems. It also enables greater collaboration between the different disciplines involved – such as safety, cockpit and seat design – thanks to the use of a common platform.

Audi engineers start by setting up the folding sequence in Sim-Folder. They then simulate the folding process using ESI’s Virtual Performance Solutions and add the correctly folded airbag to the car model. The positioning of the dummy and the inflator characterization are completed using Audi in-house tools, that provide the input

for the accurate deployment simulation using ESI’s Finite Point Method.

Following this new method, the initial curtain airbag can be modeled and the associated simulation run in one or two days, while changes needed for new design iterations can be processed within a half day. The driver airbag that initially took from one to three days to model can now be modeled overnight. The passenger airbag is the most difficult. It currently takes two weeks for the initial run, but Audi aims to reduce this to one week.

“ The major benefit of sim-ulation is that we have a reproducible work-flow keeping in details the influence of one or several parameters. With Sim-Folder, when we change one folding sequence, we can run the entire process again and obtain a folding vari-ation overnight instead of one week for curtain

“ We developed a sys-tem to predict the thin-ning profile on blister formation and the bar-rier property using PAM-FORM. With PAM-FORM we’re able to predict this behavior more accurate-ly with great flexibility and user friendliness, all of which has helped us

speed up our process.”Samir Bagalkote,

Bilcare Research.

Thermoformed plastic blisters are widely used to package pharmaceutical dosages because of their low production cost and high performance. Recent regulatory requirements have been introduced, calling for a stronger moisture barrier when packaging many new and existing pharmaceutical products. The challenge is to provide a sufficient moisture barrier while also meeting cost and environmental concerns.

Meeting moisture barrier requirements is difficult in blister packing because the packaging material undergoes heavy deformation during the thermoforming process ; affecting the thickness distribution of plastic film after the cavity formation. Non-uniform thickness and thinning in the corners of the container are important factors that determine the adequacy of the thermoforming method.

Bilcare rolled out a packaging development method named BilcareOptima™, that assesses the degradation profile of the drug formulation and determines the barrier property required of the package that will protect the product during its shelf life. The company sought a method to predict the effect of material properties, and wall thickness distribution on the barrier properties of polymeric films after thermoforming to a blister pocket. This information is needed to develop the optimal blister cavity design.

PAM-FORM enables a forming simulation in a 3D Virtual Environment and the associated post processor produces a unique view of the topography of thickness, stress-strain distribution, forming zones, etc. in the thermoformed pocket. Film visco-elastic deformation behavior was validated based on comparison of the experimental and simulated stress-strain data at various temperature and strain rates.

NASA uses Virtual Missions to simulate mission processes and resource flows. Virtual Missions also help uncover issues and validate procedures and software prior to executing an actual mission.

Virtual Missions have historically been paper-based processes that involve the teams getting together over a conference table to identify mission events, task inputs and outputs, the mission schedule, and required resources. Obviously there are many limitations inherent in this methodology, including the time involved, the level of detail possible, and the availability of the necessary participants.

NASA needed to address the knowledge limitations for the participants, as well as the time, and detail of their traditional, paper-based approach to develop higher-fidelity and lower risk mission plans with less effort and in less time. To that end, in 2010, NASA’s Marshall Space Flight Center and Ames Research Center collaborated with Qualis and ESI to build a suite of software tools to support server-based Virtual Missions.

A team from NASA, Qualis and ESI designed a simplified and efficient process for the collection of mission events, task input/output, schedules and organization responsibilities which were entered and made accessible through a web database. The team then automated the trans-

formation of the NASA database into several process visualization and simulation tools includ-ing a Vdot™ process management model which enables geographically distributed participants to walk through the virtual missions and ultimately execute and manage the actual mission.

The NASA solution has 5 key components: . Web accessible process database,. Defined format spreadsheets,. Macros to produce standard file formats,. Suite of process/requirements tools,. Models and reports from the tool suite.

The web database provides a means of sourcing information from staff around the world to refine the mission processes ; a process known as ‘crowd-sourcing’.

Once an initial crowd-sourced mission is ready, the Excel macros automatically produce a Vdot™ process model suitable for distributed, human-in-the-loop Virtual Mission Simulation.

One key advantage is that the distributed Virtual Mission participants need little to no process training. When a human task is ready, the participant receives an e-mail with a link to an interactive web page defining the task. Vdot™ orchestrates any subsequent tasks ; human or automated.

This solution produces better mission plans through rapid round-trip process engineering. Vdot™ orchestrates the key activities: data capture, process analysis/improvement, simulation, and metrics gathering.

“ We used SYSPLY to predict

virtually the residual stress-

es, early in the develop-

ment process. There was a

good correlation between

the virtual and the physical

results. The use of simula-

tion with SYSPLY was really

successful.”Dr. Olga Klinkova,

Research Engineer, LTDS-ENISE & Centre de la Science

des Matériaux et des Structures

As part of the LCM-SMART French National Research & Development project, the Laboratory of Tribology and System Dynamics (LTDS) at the École Nationale d’Ingénieurs de Saint-Étienne (ENISE) used ESI’s SYSPLY Finite Element (FE) simulation tool to investigate the distortion and the residual stresses that occur during a liquid composite molding (LCM) process.

The study focused on an L-shaped composite aerospace structural component. The manufacturing process consisted of placing the composite material in a rigid mold and then curing it in an autoclave. The effort of residual stresses appeared during the molding process when the part was removed from the mold. The part was then machined to obtain a smooth surface. The relatively simple geometry of the part chosen for the study made it easy to understand the distortions that occurred during the molding process.

The machining process consisted in milling the residual stresses formed during the manufacturing process, hence representing thermo-mechanical phenomena. The thermal source inducing the heat flux coming from the primary shear zone was related to the friction coefficient from the material removal process, while a mechanical source represented the pressure. Engineers hence used SYSPLY to simulate the machining process by applying thermal and mechanical loads directly to the final cut surface. The ability of SYSPLY to simulate the complete manufacturing process in a single application provided a significant advantage.

The LTDS laboratory succeeded in predicting the necessary level of residual stresses to avoid reaching material rupture. The use of an composite mold made it easy to measure the residual stresses induced on the model during

Based on simulation results, the laboratory later offered some of its customer to use one of thean optimized mold design. Simulation substantially reduced the amount of physical prototyping that was needed to produce a quality part. As a result, the development cost and time for the part was significantly lower than with previous comparable projects.

In its search to to improve safety, fuel economy and decrease environmental impact, the automo-tive industry is continually searching for stronger and lighter body panel materials. At the same time, appearance and basic structural integrity are just as important as ever. Exterior panel surfaces must be free of tool marks and any other defects ; including signs of necking caused by excessive strain.

AETHRA, like other automotive suppliers dealing with sheet metal forming, frequently faces the challenge of working with new materials. These need to incorporate product designs with more complex geometries and often include thick-nesses reduction, as companies strive to reduce product weight. Surface defects are frequently encountered during the tool tryout period and the resulting tuning process can become very expensive and time-consuming. Furthermore, skilled personnel and expensive equipment and materials are dedicated to correcting problems instead of making parts needed by the customer. This problem is so serious that it is making it dif-ficult for many stamping companies to operate profitably.

In 2008, AETHRA’s engineering department began a search for stamping simulation software that could support the goal of improving part quality while reducing tool tryout times and the number of material blanks needed for testing. After several months of visiting users of simulation tools and trying various software packages, AETHRA con-cluded that ESI’s PAM-STAMP 2G was the best fit for the company’s needs. This decision was prima-rily based upon PAM-STAMP 2G’s superior ability to simulate surface quality issues.

Soon after acquiring PAM-STAMP 2G, the engi-neering and the tool testing teams from AETHRA used simulation in an attempt to duplicate the causes of a specific defect that had been observed during physical testing. This effort was supported

by ESI’s teams in Brazil. The simulation results cor-related very well with physical testing and the software demonstrated the ability to predict splits, wrinkles, superficial defects and tool marks.

AETHRA has consequently incorporated simu-lation into tool tryout for every new product using the following workflow:. Simulate the stamping operation ;. Run trial parts on a stamping press ;. Compare real and simulated parts ;. Modify the simulation model until the problem is solved ;


. Adjust the real die to match the simulation model that solved the problem.

The result has been a significant improvement in product quality and reduced tryout time prior to die release to AETHRA’s press shops.

Simulating results close enough to anticipate splits, wrinkles, superficial defects and tool marks

this field, so this is definitely a competitive

advantage for Cummings.” said Beau Biller,

Engineering Manager, Forensic Scientist,

Cummings Scientific, LLC. “Visual-Safe MAD is

a great tool for meshing, we could not get any-

thing from Madymo alone, that’s why we got

involved with ESI”, he continued.

According to Beau Biller, using Madymo would

have made it impractical to obtain such results

because building manually the model within

Madymo takes 20 times more man hours.

The conclusion of their study was that, what-

ever the helmet, the young man would have

suffered the same amount of injury because of

the speed and the strength of the impact.

“ESI provided our company with a cost effec-

tive and powerful tool to complete projects

that would have otherwise been nearly impos-

sible” concluded Beau Biller.

TOA Industries uses simulation to control springback in thin ultra-high strength steel stamping partsAdjusting manufacturing processes to start using high strength lightweight materials that help

reduce vehicle weight and CO2 emissions

ABOUT TOA INDUSTRIES CO. , LTD.

TOA Industries, based in Japan, produces a wide

range of automotive components including front

suspension cross members, frames, pillars, side rails,

link assemblies, arm assemblies and radiator panels.

“ PAM-STAMP 2G, which provides high accuracy in springback analysis, has become an essential tool for us to achieve early delivery at low cost. To develop ultra-high strength steel auto-motive parts into mass production in a short period of time, accurate early assessment is very important. By using the Yoshida-Uemori mate-rial model and taking into account the Bauschinger effect , we improved springback prediction accuracy on 980MPa level parts. As a result, we suc-ceeded in reducing the amount of physical trial

and error cycles.”Mr. Nobuyuki Seki,

Subsection Manager, 1st Production Engineering Department,

Stamping Engineering Section, TOA Industries Co., Ltd

The Automotive Division of TOA Industries Co., Ltd. manufactures vehicle body and suspension parts. Like many automobile manufacturers, TOA Industries are progressively switching to ultra-high strength steel to reduce the weight of vehicles in order to cut CO2 emissions without sacrificing safety and performance. Given the exceptional yield stress of ultra-high strength steel, the manufacture of parts from this material can be challenging, with problems often arising from dimensional deviation due to springback.

To create dies for use with high strength materials in a short time frame and at low cost, springback must be addressed at the design stage instead of accepting trial-and-error correction once the die is made. TOA Industries has found that, for many components made of ultra-high strength materials, conventional analytical methods are unable to predict springback accurately. For example, when a 1.2 mm thick 980MPa-class material was used for a B-Pillar Inner, the simulation did not correlate well with testing. In contrast, simulation of a Central Pillar made with 2.0 mm thick 980MPa-class material showed good correlation with physical testing.

Analysis of the behavior of blanks during the stamping process revealed that the B-Pillar Inner was subject to greater unbending deformation than the Central Pillar. It is known that the stress-strain relation during unbending deformation is different from that during bending deformation, owing to the Bauschinger effect. However, the Isotropic Hardening Material Model generally used in the previous forming simulation software is unable to take the Bauschinger effect into account. This explains the lack of accuracy of springback prediction in the B-Pillar Inner.


TOA Industries therefore decided to apply the Yoshida-Uemori model, which makes it possible to take the Bauschinger effect into account. PAM-STAMP 2G predictions displayed appropriate correlation with the physically stamped part.

TOA Industries used simulation to design dies that are producing ultra-high strength material parts in mass production for vehicles now available on the market.

B-Pillar Inner: PAM-STAMP 2G results obtained with Isotropic Hardening Model above (52.3 % of the points within +/- 1mm of physical test results), and using the Yoshida-Uemori model

Epcor Foundry reduces mold modification costs using QuikCAST

Traditionally, aluminum molds are designed by a skilled patternmaker based on their experience and validated through a series of trials before initiating production. They are notoriously difficult to get exactly right on the first go-around.

To overcome this manufacturing challenge, Epcor Foundry looked at several different casting simulation software packages and selected ESI’s QuikCAST: an entry level package at a competitive price, which is very easy to use. Epcor Foundry tried QuikCAST on a few trial parts and found that it was able to accurately simulate its molding results.

Epcor Foundry use automatic molding machines - DISA Match130 (20 X 24 flask) and Sinto FBO III (20 X 24 flask). Prior to purchasing QuikCAST, Epcor Foundry ran a 356 aluminum supercharger housing mold with an iron chill to accelerate the solidification process and to eliminate shrink and/or porosity at the base of the rotor bores. The manufacturing process was working fine but the chill was adding cost to the project, including upfront tooling expenses, part complexity and labor.

Paul Kiefer at Epcor Foundry’s sister company HiTech Shapes and Designs then decided to use QuikCAST in order to simulate the same exact design and saw areas of shrinkage in the heavier areas of the part and in the isolated bolt bosses. The ability to visualize the casting process as a time sequence provided an excellent tool to help change the design. Kiefer tried a few changes including moving the gate position and adding risers to feed additional metal into the mold as it cools. After making these changes, Kiefer re-ran the simulation, which confirmed that the changes achieved the desired results. The ability to show the simulation results to the customer was very helpful in obtaining confidence in the new design.

“ Without simulation it could have taken much longer to optimize the design. However, with QuikCAST, the ability to visualize the casting process made it possible to get the design right the first time. Since implementing the software we have saved time and ultimately money. All in all, we believe that simulation has helped us improve our competitive position by delivering a better product to our customers in less time.”

Mike Maratta,

Program and Engineering Manager,

Epcor Foundry, Cincinnati, Ohio

Once the design was frozen, Epcor Foundry cut the tooling for the core boxes and patterns and ran a few sample parts. The mold produced good parts that exceeded the customer’s requirements from the very first casting. The part reached Epcor Foundry’s quality requirements and the cost was reduced by eliminating the chill.

Visualizing casting processes with ESI’s Casting Simulation Suite enables engineers to manage mold

design changes efficiently

After the design modifications, two sound castings were achieved

Epcor Foundry was thus able to make a better part straight from the gate instead of having to adapt the process on the customer’s time.

As needs evolve towards more advanced modeling, EPCOR will consider using ESI’s ProCAST simulation software. Based on powerful Finite Element Technology, ProCAST is well suited to also predict distortions and residual stresses.

ESI Group announces an agreement with CTIF to distribute SALSA 3DTo further complement of the capabilities of its Casting Simulation Suite, ESI now distributes a filling system design tool. CTIF (Centre Technique des Industries de la Fonderie), a French casting research center, and ESI Group have signed an agreement for the exclusive distribution, support and development of SALSA 3D. The tool developed by CTIF calculates efficient filling systems for pressure die casting, following experimental and fundamental rules.

SALSA3D helps calculate and size gating and running systems for the High Pressure Die Casting process. It assists in designing gates, runners and

overflows by controlling the maximum gate velocity and its thickness based on the available pressure machine. This potentially delivers significantly increased yield and reduced die development time by modeling the filling system automatically in 3D to be then validated using ProCAST or QuikCAST.

SALSA3D will gradually be integrated into the ESI Casting Simulation Suite, with the aim of offering a software combination that helps maximize productivity, reduce development time and improve the quality of parts.

ESI and JSP offer ARPRO® electronic data sheets for virtual seat prototypingESI’s virtual seat prototyping solution

PAM-COMFORT predicts detailed information

related to seat design – including possible cosmetic

defects due to the manufacturing process, and

seat performance in terms of occupant posture

and seating comfort. PAM-COMFORT uses the

physical parameters resulting from each stage of

the seat manufacturing and assembly processes as

an input to the following stage in order to ensure

a high level of precision, whatever the seat design

and the anthropometry of the occupant.

ESI recently announced an innovative and

collaborative project with JSP, a leading provider

of strong and lightweight expanded polymers.

The physical properties of ARPRO® Expanded

Polypropylene, one of JSP’s high-end sustainable

foam products, will be included into PAM-

COMFORT’s library in order to streamline

engineering development processes.

Virtual seat prototyping with ARPRO® high performance material

A high performance material, ARPRO® offers

unique combined properties to manufacturers and

seat development engineers alike: high strength-to-

weight ratio, light weight, chemical inertia, thermal

insulation, energy absorption, acoustical properties

and 100% recyclability.

This intelligent partnership will allow the simulation

of ARPRO®’s unique product properties via a

rich, digitally enhanced library – using advanced

encryption techniques – without sharing any of

ARPRO®’s innovative and protected IP. This removes

a barrier to innovative design considerations, which

are typically impeded by the need to physically test

the intrinsic properties of materials.
