The final goal of this study is to predict the effects of airbag on occupant safety when the passenger is in OOP (Out-Of-Position) condition. To this end, accurate and efficient prediction of airbag deployment is essential. Control volume method and particle method were compared for airbag deployment simulation. The drop tower test was simulated with both methods by commercial code LS-DYNA and the results were compared with the test data. At the initial stages of inflation the particle method showed better agreement with the test data while the control volume method showed better agreement with the test data at the later stages. A rational choice would be to start with the particle method initially and then switch to the control volume method later for the rest of the process.
