| The Container Analysis Fire Environment (CAFE-3D) computer code was developed at Sandia National Laboratories to simulate heat transfer from large fires to engulfed packages for transportation risk studies. These studies require accurate estimates of the total heat transfer to an object and the general characteristics of the object temperature distribution for a variety of fire environments. Since risk studies require multiple simulations, analysis tools must be rapid as well as accurate.; In order to meet these needs, CAFE-3D links the Isis-3D Computational Fluid Dynamics (CFD)/Radiation heat transfer fire model to a finite element model of the package.CAFE-3D must be benchmarked with experimental data before it can be used for risk assessment studies with confidence.; The current work benchmarked the CAFE-3D with recent experimental measurements. In this benchmark simulation, CAFE-3D accurately reproduced the calorimeter temperature data from a 30-minute fire experiment, in less than 10 hours on a standard desktop workstation.
