Application Field

Present guidelines define modeling and validation requirements for numerical airbag models in Radioss with Finite Volume Method (FVM).

These guidelines are based on Radioss version 2017.2.3 double precision which is used by many airbag manufacturers. The single precision version of Radioss cannot be used for airbag calculations. The guideline requirements are based on the common practice of airbag modeling. Some of the requirements are not directly connected to the FVM but are recommended to create an airbag model which is easy to understand and incorporate in crash simulations.
  • FVM - Finite Volume Method
  • FV - Finite Volume
  • UP - Uniform Pressure
