Crash-tests simulations by LS-DYNA code on the HPC AMD64 Cluster

Crash-test simulations of the car models by LS-DYNA code are carried out on the HPC 16 CPU AMD64 Opteron processors Cluster. Simulations are based on the large 3D finite element car models that contain more then one million DOF. Architecture and benchmark of the HPC 16 CPU AMD64 Cluster were tested by engineering applications with commercial engineering codes LS- DYNA instead of synthetic benchmark. For this purposes several tasks were taken from www.topcrunch.org. The tasks named “3 Vehicle Collision” and “Neon”. Benchmark tests have shown pretty good results for such type of industrial problems and confirmed that Opteron processor on AMD platform is preferable to Itanium processor on Intel platform. LS-DYNA code was used for crash analysis of real modern cars produced by AVTOVAZ in Russia. HyperMesh software was used to create finite element mesh and for a pre- processor for LS-DYNA solver. To visualize simulations as 3D virtual reality objects crash analysis results obtained on HPC Cluster were imported on 3D Virtual reality system named WorkBench. WorkBench 3D virtual reality system contains soft screen, two multimedia projectors, computer with dual heads graphics adapter and tracking system Flock of Birds. COVISE software was used for visualization of CAD models of the cars and crash analysis results as 3D virtual reality objects.
