"Pam-crash 2G, by its multi scale capability, enables CAE engineers to evaluate design variants in a very efficient way, taking local effects into account," explains 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, 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 Pam-crash 2G 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 crashes," confirms Dr Greve, of the CAE Methods Department at Volkswagen Group Research.
Taking into account the transport industry's permanent focus on weight reduction, Pam-crash 2G offers the modelling of advanced materials such as 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, including contact interfaces or spot welds.
It has also been extended to other areas, for example in manufacturing for composite forming or stamping to support simulation-based design.
ESI Group supplies a complete compute 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-bit 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.
Pam-crash 2G, the virtual testing solution for crash and safety professionals, comprises three main components.
Firstly, a solver offers state-of-the-art physics-based models for crash and other impact problems - its key capabilities include advanced material models, coupling with manufacturing process simulation, a mesh-free CFD method for airbag modelling, and a highly scalable parallel solution.
Secondly, the Visual Environment portfolio is a suite of highly productive CAE process automation products.
Finally, there are validated compute models, including crash test dummies, impactors, barriers, and a unique family of human body models.
