ESI (17)

ESI Group announced the new version of its casting simulation software ESI ProCAST, a virtual manufacturing solution of ESI that enables foundries to improve the design and quality of the parts they produce. ESI ProCAST predicts manufacturing defects early and without the need for costly part production. Consequently, part design and manufacturing processes can be corrected well-ahead of production, achieving lower scrap rates and delivering quality parts in a consistent way.

ProCAST 2016 promises even quicker turnaround times with new workflows dedicated to gravity casting and high pressure die casting. Set-up time for gravity casting, the most widespread sand casting process, is reduced to just a few minutes, while the workflow for high pressure die casting addressed machine selection and bridges the gap between design and production to deliver increased efficiency on the shop floor.

Casting simulation helps industrial manufacturers and foundries comply with new and increasingly stringent market expectations and achieve the highest quality and productivity possible. To that end, ESI ProCAST provides a complete solution, covering all casting processes and the alloys used in diverse industry sectors and the latest 2016 version focuses on key industrial challenges specifically related to sand, investment and die casting processes in the automotive, aerospace and heavy industries.

In regard to sand casting processes, ESI ProCAST 2016 has been enriched with a dedicated workflow for gravity casting, enabling simulation set-up within minutes. Taking all process parameters into account to deliver highly precise results, this step-by-step approach can be customized to fit any foundry’s specific requirements and processes, delivering improved usability when repeating tasks. The new functionality is easy to use and can be mastered by any foundry within a few days.

Another notable enhancement to ESI ProCAST 2016 is the introduction of the machine selection workflow that draws on a dedicated database for high pressure die casting (HPDC) machines, including the Colosio machines. The new functionality enables the user to define the operating point and operating zone for any machine, using the Pressure (P)-Flow Rate(Q)² graph. This information is linked to ProCAST’s solver to achieve virtual piston control in real time. Enabling a user to set-up parameters just as on the real machine, this enhancement provides a considerable time gain for process-design, and delivers the possibility to run a virtual benchmark and select the appropriate machine for specific jobs.

ESI Group announces the signature of a protocol for a multi-year strategic collaboration agreement with Astrium, Europe’s leading space technology company. Officially signed in Paris on November 16, 2012 during the Astrium R&T days, this agreement aims at developing Virtual Prototyping technologies and promoting Virtual Engineering in the space domain, and addresses critical needs in the design and manufacture of next generation launchers.

Astrium and ESI Group have implemented this long-term collaboration agreement with the intent to jointly ”co-create” new and innovative technologies, processes, and development methodologies for the space industry and its next generation launchers. The objective of this collaboration is to enable the space industry to rapidly build robust virtual prototypes of components, subsystems and systems of the new and improved launchers at various and early stages of the design and development cycle.

At the signing ceremony held in Paris on November 16, Hervé Gilibert, CTO and CQO of Astrium Space Transportation, described the collaborative intent of this agreement:

“For Astrium, today’s agreement with ESI Group sets a new standard in how we collaborate with our key industrial partners. Our intent is to align objectives and join forces to drive Astrium and its partners to the leading edge of global innovation, in order to maintain and reinforce the European leadership of Ariane in the global commercial launch services market.

The relationship of Astrium with ESI dates back to the 70’s before the creation of the EADS group, when ESI successfully accompanied the development of numerical simulation in the aerospace and aeronautical industry with the European Space Agency ESA/ESTEC. ESI has continued to pioneer Virtual Prototyping worldwide, primarily in the automotive industry where it has achieved most spectacular results.

Today both parties are convinced that a joint collaborative effort between Astrium and ESI is the best partnership solution to address the new global challenges of the space industry. We’re setting the scene for the next generation of space vehicles and technologies, while promoting Virtual Prototyping and Virtual Engineering.”

Eric Daubourg, COO of ESI France added: “Under this multi-year agreement, ESI is fully committed to supporting Astrium-ST in its quest for new methodologies in Virtual Prototyping that address the specific requirements of advanced space technologies. Our partnership with Astrium and the space community will enhance the national and international recognition of launcher and space technologies developed in Europe.”

Despite being at the forefront of technology, the European space industry must indeed face global challenges that are rising with the arrival of new international players. In this environment, the overall performance of launchers and their modularity and flexibility to accommodate customers’ needs must keep improving while manufacturing and operating costs must be drastically reduced. New designs, new manufacturing processes, and new multi material solutions have to be invented, tested, validated, and certified in record time.

Vincent Chaillou, COO, ESI Group concluded: “Such an evolution cannot be conducted using the traditional approach of trial and error on increasingly expensive ‘real’ physical prototypes. Virtual Prototyping enables the mandatory early evaluation of design and fabrication alternatives, and allows the rapid corrections of identified deficiencies.”

ESI Group, announces the release of PAM-RTM and PAM-FORM 2012, two numerical simulation applications dedicated to the manufacture of composite parts. This composites manufacturing simulation suite is a unique industrial solution to define and optimize manufacturing processes of dry textiles and prepregs, with the objective of achieving better part quality and lower production time cycle and cost.

Developed through partnerships in several fields including automotive, aerospace and defense, PAM-FORM is a virtual manufacturing solution dedicated to non-metallic forming processes. PAM-FORM enables realistic and predictive forming and pre-forming simulation of laminated composites, allowing engineers to select the most appropriate material, the right tooling design, and the best process parameters. “PAM-FORM helped us achieve our project goals: lower weight and cost of production while preserving the mechanical properties of the part. Additionally, it provided us with more information on optimizing our production process which can be reapplied to similar projects,” affirms Josef Krena, Development Manager at LETOV LETECKÁ VÝROBA Ltd., part of Latécoère Group.

PAM-FORM allows engineers to predict manufacturing defects, including wrinkling, excessive shearing, bridging or inappropriate thickness distribution; and to correct them by modifying the process parameters or the tooling. Josef Krena confirms: “Recently, we designed a forming tool for which we used PAM-FORM to optimize its tipping angle. It helped us reduce the cost of that tool without affecting the quality of the part.”

A best-in class tool, PAM-FORM addresses a large range of composites manufacturing processes: stamping, diaphragm forming, hand lay-up and rubber pad forming.

The latest enhancements mainly focus on dry textile preforming.

PAM-RTM is a simulation software application for resin injection or infusion of composite preforms with or without inserts and core materials. It provides an accurate prediction of the manufacturing process of thick, complex or large composite components commonly encountered in wind energy, aeronautics and automotive industries.

PAM-RTM covers a wide range of Liquid Composites Molding manufacturing processes: Resin Transfer Molding (RTM), Vacuum Assisted RTM (VARTM), Vacuum Assisted Resin Infusion (VARI), Compression-RTM and Articulated-CRTM (CRTM and A-CRTM). Simulating these processes allows engineers to determine the optimal injection strategy, minimize the injection time, control the curing cycle and manage the resulting porosity of the finished part.

Professor Jeferson Avila Souza, from the Federal University of Rio Grande, Brazil, comments, “We have chosen PAM-RTM due to its ability to run 3D models in a realistic way and simulate resin injection in parts such as small boat hulls, propeller blades and automotive parts. We have also considered that it can be handled by group members that do not directly work with numerical techniques. The simulation process is steady, leading to quick and reliable results.”

New in version 2012, a high performance solver manages thermal analysis of preheating, non-isothermal filling and curing in an even more accurate manner. Additionally, thanks to the active support of the University of Nottingham in the UK, a permeability database addressing a large number and variety of textiles is now available for PAM-RTM customers, and will be enriched over time.

Latest Release of ESI’s Casting Simulation Suite

Written by

ESI Group, pioneer and world-leading solution provider in virtual prototyping for manufacturing industries, announces the latest release of ESI's Casting Simulation Suite, composed of ProCAST & QuikCAST. The suite provides a predictive evaluation of the entire casting process, including filling and solidification defects, microstructural changes and part distortion. It enables rapid visualization of the effects of design changes for cast parts, to aid in making the right decisions from an early stage of the manufacturing process. Virtual Prototyping enables foundries to shrink product development costs, reduce time to market, and increase product quality.

This new release includes a complete and new user environment, with a modeler that drastically reduces the preparation time thanks to a new methodology, new interface and enhanced automatic assembly. Also, the first release of the new pre-processor, Visual-Cast, provides set-up of process conditions straight onto the CAD topology, instead of onto the meshing. This gives the possibility of adapting the model to the simulation needs without resetting the process definition. This version of the Casting Simulation Suite also provides an advisor to assist in computing the mechanical properties of aluminum after age hardening treatment for parts like wheels, suspension components, cylinder heads and engine blocks. This tool has been originally developed by Rio Tinto Alcan, and by Michel Garat in particular.

New microstructure models are now available; for example for Ni-Resist and Compacted Graphite Iron, materials mostly used in the automotive industry.

To ensure sound castings, major functionalities like core gassing, oxide particles tracing and prediction of burn-on and mold penetration have been implemented.

In addition, users will benefit from the results of global research projects on light-weight materials and superalloys that will lead to improvements in centrifugal casting modeling and in the prediction of micro-porosity.

To 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.

SALSA 3D 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 thickness based on the available pressure machine. This potentially delivers significantly increased yield and reduced die development time and the filling system can be validated using ProCAST or QuikCAST.

SALSA 3D will be integrated gradually 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 releases Virtual Performance Solution 2011

Written by

ESI Group, pioneer and world-leading solution provider in virtual prototyping for manufacturing industries, announces the release of Virtual Performance Solution (VPS) Version 2011. Virtual Performance Solution enables ESI’s customers to shorten product development time by mastering design iterations and reducing costs while ensuring high quality standards.

The latest version of Virtual Performance Solution was developed to address today’s main industrial challenges. How to cope with new safety and environmental regulations for transportation, while reducing weight? How to anticipate the impact of new materials and manufacturing processes on product performance? How to reconcile conflicting requirements and bring revolutionary changes to increasingly complex products, while cutting development costs and time drastically?

Virtual Performance Solution 2011 provides numerical simulation across multiple domains: crash, impact & occupant safety; passenger comfort; linear and nonlinear statics & dynamics; strength and thermal performance; noise, vibration & harshness (NVH); and, most recently, interior acoustics.

New enhancements include a glass model to simulate head impacts on a vehicle’s windscreen; required by part of the Euro NCAP car safety performance assessment program. This new model was quickly adopted at Volkswagen AG, where Project Engineer Dr Helge Liebertz, commented: "At Volkswagen, we have been using Virtual Performance Solution for several years now, and recently, in collaboration with ESI, we improved head impact simulation on windscreen. Using a new non-local failure criterion for laminated glass in Virtual Performance Solution 2011, we could calibrate one criterion and evaluate its accuracy by comparing with several experimental results. We confirm its use at an industrial level as the criterion works very well for multiple load cases."

VPS 2011 offers unique multi-physics capabilities for multi-domain optimization with a single core model. It enables collaborative and simultaneous engineering work across domains and components, taking into account coupling effects, while saving model translation tasks between domains. Not having to deal with multiple solvers and individual processes for each product part leads to a significant reduction in the workflow’s complexity and hence enables faster design changes. VPS also allows customers to optimize safety margins, by improving simulation quality thanks to proper consideration of contacts, nonlinearities, and manufacturing history. Furthermore, VPS helps reduce IT costs by using one single scalable solution with fewer software installations.

VPS 2011 new features for NVH engineers include an improved interior acoustics module to predict the low-medium frequency response to structural loads.

The new VPS edition also integrates PAM-COMFORT, ESI’s solution for virtual seat prototyping. Along with the simulation of the trimming process, PAM-COMFORT accurately predicts the behavior of the seat under numerous loading conditions and for various design changes.

All simulations are fully compatible and available as a single package in a common user environment.

"This new release of Virtual Performance Solution includes new capabilities for improving not only vehicle crash worthiness and occupant safety, but also the passenger’s experience in general. It is now possible to decrease structural vibration and improve in-car acoustics, for instance; two parameters that directly impact a car’s ‘quality feel’.

ESI Group Announces New Release of VA One

Written by

ESI Group pioneer and world-leading solution provider in virtual prototyping, announces the release of VA One 2010.5. VA One is a complete solution for simulating noise and vibration across the full frequency range and seamlessly combines Finite Elements, Boundary Elements, and Statistical Energy Analysis (SEA) in a single model. This new release includes functionality for modeling BSR (Buzz, Squeak and Rattle) and Aero-Vibro-Acoustics.

Buzz, Squeak and Rattle (BSR)

BSR is an acoustically perceived quality attribute that consistently ranks as one of the top “things gone wrong” for many new products. The VA One 2010.5 release includes unique functionality for efficiently predicting the loudness of BSR events that occur when a product is exposed to low frequency random noise and vibration. The new functionality is available to all existing VA One users and can be used to improve product quality and reduce the risk of warranty costs associated with product recalls.


Accurate characterization of interior noise due to exterior flow over a structure can be a challenging task. The VA One 2010.5 release simplifies this task with the introduction of new functionality for modeling complex fluctuating surface pressure loads using data from CFD calculations or wind tunnel/flight tests. This new functionality is ideally suited for characterizing complex sources at low, mid and high frequencies. The VA One 2010.5 release also includes Aero-Acoustics functionality for modeling the radiation and scattering of exterior flow noise using Boundary Elements and Fast Multipole Boundary Elements.

Productivity enhancements

The VA One 2010.5 release contains around 70 additional performance and productivity enhancements across all modules.

"At Western Digital we are committed to designing quiet products for the management of digital information,” said Zakir Quabili, Principal Engineer at Western Digital. “VA One is an important tool in our noise and vibration design process.”

“We are pleased to announce the release of VA One 2010.5,” said Dr. Phil Shorter, Director of Vibro-Acoustic Product Operations at ESI Group. “The new methods for modeling BSR and Aero-Vibro-Acoustics in VA One 2010.5 are the result of a long term research program and ensure that our users have access to state of the art methods for vibro-acoustic analysis and design.”

ESI Group, a pioneer and world-leading solution provider in virtual prototyping, today announced the success of the composites simulation conference held on March 30, 2011 at the Paris-based JEC composites show.

With over 1,000 exhibiting companies, 27,000 visitors and 96 countries represented, the JEC show in Paris enjoys the status of being the biggest composites exhibition in the world.

ESI has actively participated in this event during the past decade and this year, for the second time, ESI's Composites Solution Manager, Patrick de Luca, co-hosted a conference dedicated to composites simulation. The conference program included a series of presentations from leading experts in the field of composites from around the world:

1) "Simulations for materials and manufacturing processes in composite intensive industries" by David Hudson, Director of Product and Market Strategy at Vistagy.
2) "Virtual design of lightweight components made of textile reinforced composites" by Professor Werner Hufenbach and Albert Langkamp from Technische Universität Dresden; Alexander Pabst, Project Manager and Research Engineer at Rolls-Royce Deutschland and Thomas Pyttel, Technical Consultant at ESI GmbH.
3) "Study of SAFRAN open 60' race yacht crashworthiness" by Nicolas Diot, Engineer - Equipments Mechanical Systems Design Department at Safran Engineering Services.
4) "Simulation of the Autoclave Assisted Resin Infusion process" by Solange Amouroux-Berthe, Process Engineer, Advanced Technologies Development Center at Dassault Aviation.
5) "Fiber simulation of distortion in composite structures" by Christian Brauner, Scientific Assistant at Faserinstitut Bremen E.V.
6) "Mechanical behavior in hybrid textile composite materials" by Dr. Asami Nakai, Associate Professor at Kyoto Institute of Technology.

Patrick de Luca, ESI Composites Solution Manager, commented, "every year thousands of people look forward to visiting the Paris JEC Composites show to find new ideas, partners or solutions that will foster their own innovation. The great success of the Composites Simulation Forum demonstrated that simulation technology plays a key factor in helping the composites industry meet its objectives. It is fascinating to see that beyond the large variety of origins of delegates, one can feel the common need for an end-to-end virtual prototyping solution."

Delegates at the JEC show 2011 also had the opportunity to learn more about ESI's Composites Simulation Suite by visiting ESI's booth in the 'software village' exhibition area.

In addition to managing enterprise workflows and simulation content within VisualDSS and its web client, customers will also benefit from this Decision Support System (DSS) for complete design lifecycle management.
Interface with various disciplines

Every application in ESI’s Visual-Environment is updated with each new release. For instance, Visual-Crash PAM 6.5 features a new Belt Tool to create a multi-point seat belt in just a few clicks and a new plot editor to visualize and edit curves, supporting the crash and safety simulation solver PAM-CRASH.

This latest release of  Visual-Environment also incorporates three new applications: Visual-CEM for computational electromagnetic (CEM) simulations, Visual-Composite Materials for composite structure manufacturing and Visual-Weld for welding and heat treatment simulations. While Visual-CEM includes a harness manager to handle all types of cable networks, from simple lines to sophisticated bundles, Visual-Composite Materials now allows the management of material data related to shape distortion simulations. As for Visual-Weld, visualization is improved thanks to the creation of weld sequence animations. The automatic creation of reports and weld lines is also available in version 6.5.
Support for NVH & Interior Acoustics

In a special release, Visual-Environment 6.6 is being simultaneously made available with version 6.5 for selected ESI customers. In version 6.6 the setup of Noise, Vibration and Harshness (NVH) simulations ranging from Structural Transfer Functions and Point Mobility Analysis to full Vehicle Interior Acoustics with road excitation, is possible. The 6.6 edition provides advanced tools to visualize acoustic coupling, create structural panels, as well as process automation for setting up NVH and Interior Acoustics models.  ESI’s Visual-Environment platform not only covers the complete sequence typically used in automotive NVH simulation, but also extends to the integration of Porous Elastic Materials (PEM) for improved predictability of the sound pressure level experienced by drivers and passengers.

“Our new NVH and Interior Acoustics module allows customers to improve their productivity by reusing data already available from other domains like Crash, Strength and Stiffness. Furthermore, the physical realism and accuracy of the NVH solution can be enhanced by bringing in the effects of the manufacturing and assembly history on the mechanical properties of the parts and assemblies,” said Willem Van Hal, NVH Product Manager at ESI Group.

“Our customers are our coaches and their constant feedback has been instrumental in guiding us forward,” said Anitha Nanjundaswamy Rao, Platform Product Manager at ESI Group. “With this latest release of Visual-Environment, ESI comes closer to delivering to its customers an integrated platform for End-to-End Virtual Prototyping.”
