ESI group's Pam-Crash 2G allows the modelling of advanced materials like honeycomb, super-elastic alloys, plastics or adhesive bonding.
ESI group has released 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 allows the modelling of advanced materials like honeycomb, super-elastic alloys, plastics or adhesive bonding.
In restraint system design, Pam-Crash 2G's 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 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.
Pam-Crash 2G is comprised of three main components: first, a solver offering state of the art physics-based models for crashes.
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.
The software also includes the visual environment portfolio, a suite of highly productive process automation products.
Finally, the software includes validated compute models, including crash test dummies, impactors, barriers, and a family of human body models.
