LS-DYNA is an industry-leading explicit simulation software used for applications such as drop tests, impact, penetration, crash simulation, occupant safety, and many other disciplines. The two benchmark problems presented here use the LS-DYNA explicit FEA solver, which typically scales much more efficiently than the implicit FEA solver.
The car2car benchmark is a simulation of a two-vehicle collision. This benchmark model contains 2.4 million elements. The ODB-10M benchmark is a simulation of a vehicle colliding into an offset deformable barrier. This benchmark model contains 10.6 million elements. For the ODB-10M benchmarks, the simulation end time was set to 0.02 sec. The performance for LS-DYNA is measured using the Elapsed Time metric. This metric is the total elapsed time in seconds as reported by LS-DYNA, so a smaller elapsed time is better performance.
