New Version of ESI Group´s PAM-CRASH Software


Kimberly Elsham :
ESI Group announces the release of PAM-CRASH 2G, the virtual testing solution for impact, crash and safety professionals. The software serves clients in industries such as automotive, aerospace, consumer electronics, and material producers. It also provides benefits in time-to-market and lifetime cost over traditional manufacturing techniques. It supports collaborative work between various actors involved in the simulation process.

“PAM-CRASH 2G enables by its multi scale capability CAE engineers to evaluate design variants in a very efficient way taking local effects into account,” says Peter Ullrich, product line manager at ESI Group. “This is when you need detailed geometrical information for example to obtain a more reliable failure analysis. Compared to standard procedures, the speed-up factor in simulation time is about four to five times faster based on feedback we received from several industrial applications.”

“PAM-CRASH 2G is a solution to drive business value and gain a competitive edge. We used [the software] for front crash simulation with sub frame failure prediction. Its multi-scale coupling using subcycling enables the representation of locally refined models for detailed failure analysis. Computation time has been greatly decreased due to subcycling in comparison with standard PAM-CRASH 2G jobs. Moreover, code coupling enables further applications, like convenient handling for car-to-car crash,” says Lars Greve, CAE Methods, Volkswagen Group Research.

Taking into account the transport industry’s permanent concern of weight reduction, PAM-CRASH 2G proposes the modeling of advanced materials like honeycomb, super-elastic alloys, plastics, or adhesive bonding. In restraint system design, PAM-CRASH 2G’s unique Finite Point Method (FPM) addresses how gas flow affects airbag inflation. All these new features enhance accuracy and improve ease-of-use, which result in the most efficient solver currently available with respect to high performance computing and software quality.

The PAM-CRASH 2G environment is an advanced enterprise solution for CAE data management providing an open and interoperable framework for IMPACT, CRASH, and SAFETY applications. Visual Crash for PAM (VCP), the dedicated pre-processing solution to PAM-CRASH 2G’s solver, uses solver algorithms directly to save time for accuracy and consistency checks like contact interfaces or spot welds. It is extended to other areas like in manufacturing such as composite forming or stamping to support simulation-based design.

ESI Group supplies a complete computing model library to CAE engineers. This library includes crash test dummies, barriers, test devices, and human models according to the current safety regulations. It helps CAE engineers to save significant time in model set-up and to design high-performance cars.

PAM-CRASH 2G is available on computers running 32- and 64-bit versions of the Windows, Linux, and UNIX operating systems. It runs as a massively parallel application on computer systems supporting this capability. For more information, please visit

About ESI Group:
ESI Group is a world-leading supplier, and a pioneer of digital simulation software for prototyping and manufacturing processes that take into account the physics of materials. ESI Group has developed an extensive suite of coherent, industry oriented applications to realistically simulate a product’s behavior during testing, to fine-tune manufacturing processes in accordance with desired product performance, and evaluate the environment’s impact on product performance. ESI Group’s products, which have a proven track record in manufacturing and have been combined in multi-trade value chains, represent a unique collaborative and open virtual engineering solution known as the Virtual Try-Out Space (VTOS), enabling virtual prototypes to be improved in a continuous and collaborative manner. This integrated protocol allows all the company’s solutions to work with each other and with applications developed by independent software vendors. By significantly reducing costs and development lead times and enabling product/process synergies, VTOS solutions offer major competitive advantage by progressively eliminating the need for physical prototypes during product development. The company generated sales of nearly $90 million in 2006, employs more than 600 high-level specialists worldwide covering more than 30 countries. ESI Group is listed in Eurolist compartment C of Euronext Paris. For further information, visit
