HBM announces the version 9.1 release of nCode DesignLife, a leading solution for CAE fatigue analysis applications. Users can now more quickly solve fatigue analysis problems by using High Performance Computing (HPC) environments. A new Safety Factor product option helps assess the durability of a wider range of components used in ground vehicle powertrain engineering early in the design process.
As finite element models increase in size and fidelity, HPC environments are being used to improve simulation throughput. This enables parallel processing to go beyond the multi-core processing on a single computer by distributing the analysis across multiple machines or nodes of a compute cluster. In this way, the largest computational problems can be broken down and solved many times quicker, but hardware is not the only requirement. The computational software needs an architecture that can take advantage of this scalability by distributing the analysis tasks and required information between machines.
To address these performance demands, nCode DesignLife 9.1 can now be run in HPC environments or other multi-machine configurations using a new Distributed Processing option. nCode DesignLife supports both Intel MPI (Message Passing Interface) for Windows and Linux operating systems and Microsoft MPI for Microsoft HPC clusters.
“Previously, performance was limited by the number of processors available on a single machine and it was not unusual for a large scale fatigue analysis such as an automotive full-vehicle simulation or aerospace landing-gear to run overnight,” said Jon Aldred, Director of Product Management for HBM-nCode, “Now, turnaround time for the largest jobs can be improved by an order of magnitude with Distributed Processing, opening up the possibility more robust up-front design through simulation.”
nCode also introduces new built-in methods for performing safety factor calculations commonly used in powertrain engineering. The new Safety Factor option in DesignLife expands its ability to cover many aspects of the durability assessment needed for engines, transmissions, and drivelines. This stress-based factor of safety method is commonly used for the design of crankshafts, camshafts and pistons, and employs standard mean stress corrections or user-specified Haigh diagrams. Stresses from a complete finite element model are analyzed in a single analysis process. Other capabilities for powertrain include industry proven methods for stress gradient effects that are important for fatigue analysis of cast materials used in engine blocks, virtual shaker testing simulation for engine electronics, and thermo-mechanical fatigue analysis for high temperature components such as turbochargers.
nCode DesignLife is released as part of nCode 9.1 which provides a robust set of tools for test and CAE simulation for durability. The options for Distributed Processing and Safety Factor analysis are available as part of nCode CDS unit licensing, which offers flexible leased access to the full range of nCode 9.1 products. nCode 9.1 also incorporates nCode GlyphWorks, a graphical test data processing software that features new options for GPS data including satellite and internet-based mapping service through MapQuest Open.
