Summary:

The demand for Out-Of-Position (OOP) simulation capabilities in safety/crash software increased after the National Highway Transportation Safety Administration (NHTSA) final ruling on FMVSS 208 in 2000. However, the development of this capability involves many technical challenges. To expedite the development and manage the technical difficulties, five benchmark problems were established in this study. Each of them addresses specific technical difficulties of airbag OOP simulations. One benchmark problem has an analytical solution; one has a well-known numerical solution and others have the test results. The benchmark set was designed starting from simple Computational Fluid Dynamics (CFD) problems to the complicated OOP applications such that the bugs and algorithmic errors of the code can be easily identified. This paper summarizes the solutions, test results, and associated technical issues of the benchmark problems. The evaluations for three gas models of Arbitrary Lagrangian-Eulerian (ALE) in LS-DYNA are discussed. The simulation results of the benchmark problems are presented
