LS-DYNA® is a leading simulation solution for finite element analysis produced by Livermore Software Technology Corporation. LS-DYNA is used in a number of industries such as automotive, metal forming, and aerospace.
The LS-DYNA benchmarks suite comprises of a set of test cases covering a large range of mesh sizes, physical models and solvers representing typical industry usage. The cases range in size from a few thousand elements to more than 2 million elements. Benchmark data sets and cluster performance results are available from the independent web site www.topcrunch.org
Benchmark test case used in this study
The test case used in the results presented below is called car2car which models automotive crash simulation for the head-on crash of two minivans (Car2Car) and contains about 2 million elements.
The results for one of the test cases, car2car, presented in the graphic demonstrate excellent scalability of LSTC LS-DYNA running on Windows HPC Server 2008 R2.
The results for the test case car2car running on the Windows HPC Server 2008 and LUNUX system are published by the independent website topcrunch and are available at: http://topcrunch.org/benchmark_results.sfe
