ESI has developed a set of applications for the foundry industry to improve casting yield and quality: QuikCAST -- a fast and efficient solution for process evaluation -- and ProCAST -- an advanced tool which is the result of more than 20 years of collaboration with major industrial partners and academic institutions around the world. QuikCAST focuses on the basics of any casting process: filling, solidification and porosity prediction. ProCAST, based on Finite Element technology, is able to predict deformations and residual stresses and can also address more specific processes like semi-solid modeling, core blowing, centrifugal casting, lost foam and continuous casting.
ESI has developed an entire suite of industry-oriented applications to realistically simulate and fine tune the manufacturing processes of composites parts. These applications focus on components made of continuous fibers and thermoset or thermoplastic matrix. Manufacturing of composites parts usually goes through different operations. ESI offers an integrated solution that allows the analysis and optimization of each individual manufacturing operations but that also links these different operations by transferring material history (change in fiber orientations, curing degree, temperature distribution, etc ...) from one operation to the next.
Sheet Metal Forming
With our die face design and sheet metal forming simulation solution called PAM-STAMP, engineers can design, optimize and verify metal forming processes on computer. PAM-STAMP covers cold, warm and hot sheet metal and tube forming processes, patched and tailored blanks, and is used in all industries, including automotive, aerospace, electronics, and appliances.
At the quoting stage, users can determine blank outlines and optimum nesting for material cost estimation, and quickly develop draw dies. In the feasibility phase, die designers can model tool surfaces based on B-Spline geometry, and engineer a successful forming process without cracks and wrinkles, to specifications, including hemming, trim development and trim line and blank shape optimization. In the validation phase, engineers can precisely estimate springback, compensate the dies in the drawing operation or across multi-operations, and detect and visualize cosmetic defects just as they would on the shop floor. There is no difference in any of the software settings between the feasibility and validation phase, which ensures the best possible result quality.
Validation of the cooling efficiency of 3D tools in a press hardening process is possible with a heat transfer or a true fluid-flow (CFD) analysis. Also, since manufacturing affects material properties, which in turn affect product performance, the results of a forming process can be used to engineer a welding assembly process, with the goal to keep the assembly within tolerances and improve product performance. Finally, engineers can display and review the findings in a virtual reality environment. Virtual Prototyping ensures that component manufacturing and assembly processes deliver the designed product specifications and performance – on time, and within budget. ESI provides complete solutions for virtual prototyping of lightweight designs that deliver as good as real prototypes so designers can make the right decisions.

Virtual Performance Solution
Virtual Performance Solution (VPS) is a global solution for Virtual Product Engineering, which has its origins in PAM-CRASH, and takes into account multiple domains. In various industries, manufacturers are striving to develop greener and safer products, using lighter materials and innovative designs, while ensuring leading-edge functional standards, including safety, comfort, NVH (noise, vibration and harshness), acoustics, stiffness and durability.
VPS addresses all these key attributes and allows engineers to handle interactions across multiple - and sometimes conflicting - domains efficiently. VPS enables multi-domain optimization by reducing the number of physical prototypes, shortening design cycles and cutting development costs. The solution features a single core-model for all domains of performance and is able to run all load cases on a single cluster to limit design iterations and lead time induced by synchronization between domains.
Virtual Performance Solution faces challenges such as: How to cope with safety regulations while reducing weight? How to anticipate the impact of new materials and manufacturing processes on product performance? How to match conflicting requirements and bring revolutionary changes to increasingly complex products, while cutting the development costs and time drastically?
Virtual Seat Solution
Passenger comfort is becoming more and more important for OEMs and the seat manufacturers face new challenges: reinforced occupant safety, new requirements in manufacturing, work on the occupant posture, occupied seat transmissibility and thermal analysis are taken into account during the development of a new seat. Virtual Seat Solution (including the software previously known as PAM-COMFORT) enables virtual manufacturing and virtual comfort testing (static and dynamic) of the soft parts of the seat.
Government legislation, competitive pressure and tight development schedules mean you can’t afford to wait until your product is built to find unexpected noise and vibration problems.

CFD & Multiphysics
Computational fluid dynamics or CFD is a technology that simulates interaction of liquids and gases with surfaces, by performing millions of numerical calculations. CFD analysis is mainly carried out earlier in the design process based on which the prototype is made. With high-speed supercomputers, better solutions can be achieved. Multiphysics is basically advanced CFD involving multiple or coupled physics. For example, combining chemical kinetics and fluid mechanics or combining finite elements with molecular dynamics. Multiphysics typically involves solving coupled systems of partial differential equations.
In this area, ESI offers solutions for simple physics to complex coupled physics. ACE+ Suite is mainly CFD and Multiphysic software package serving the Semiconductor, Microfluidics, Biotech, Energy & some specific Automotive applications very well. And SYSTUS, on the other hand is again a Multiphysics tool specific to Civil applications.
Computational Electromagnetic (CEM) Solution for Full Virtual Testing Nowadays, manufacturers are required to comply with certain international Electromagnetic Compatibility (EMC) regulations. Hence complying with EMC standards in the early design stage is highly desirable. Digital EMC makes it faster and cost- effective. ESI offers unique solutions for specific industries like Transportation, Aeronautics, Defense and Electronics. ESI’s PAM-CEM Simulation Suite operates in the middle & high frequency range. Being mainly time-domain oriented, it focuses on EMC/EMI issues appearing in a wide spectrum with onboard electronics and complex cable networks. PAM-CEM is also able to handle frequency- domain as well, for Active Safety & RADAR devices.
Efield Solutions is primarily frequency-domain oriented with some time-domain features, making the overall solution complete. In the Transportation industry, Efield Solutions solves all major scenarios like antenna radiation, placement and/or optimization, rear or side window antenna designs and much more. For other industries such as Aeronautics & Defense, the consolidated solution now offers the same coupling and/or hybridizing strategy, extending it much beyond its previous limits with larger models, higher operating frequencies, and more sophisticated scenarios, taking EMC/EMI modeling one step further.
Every product engineering team deals with questions in the virtual prototyping phase, many of these covering multiple engineering domains. ESI's Visual-Environment allows these teams to work together in a single user environment, around a single core compute model. This environment has the capacity to integrate all virtual prototyping problems across CAE domains.
