Abstract : The Australian Challenge was a set of experiments chosen as a test case to establish how well computer calculations can model the blast overpressure around a complex set of structures. This paper presents the first three dImensional calculation on the Australian Challenge using CFD codes. These codes have been developed at AMRL and the Australian Challenge represents their first test in a real world' scenario. The calculations show good agreement with the experimental results. The program can now be used with a good degree of confidence in modelling other complex scenarios, reducing the need for expensive experimentation. The safety aspects of any changes in operational procedure can be evaluated quickly and efficiently. (AN)
