ESI to Launch new Version of Pam-Crash 2G

ESI Group, provider of digital simulation software, announces the release of the latest version of "Pam-Crash 2G", the virtual testing solution for impact, crash and safety professionals. It's major evolution resides in the new methodology called Multi-Model Coupling to perform detailed simulations, which is a key point of the 2006 version.

"Pam-Crash 2G offers fast turnaround with very detailed model when we need to obtain in given areas precise geometry of the deformation, or reliable rupture prediction", explains Peter Ullrich, Impact, Crash & Safety Product Line Manager ESI Group. "Instead of imposing a small time step to the whole structure, the software isolates the local areas with refined mesh."

"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 crash", confirms Dr. 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 Finite Point Method (FPM) addresses how gas flow affects airbag inflation. It's 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.
