The Uintah software suite is a set of libraries and applications for simulating and analyzing complex chemical and physical reactions. These reactions are modeled by solving partial differential equations on structured adaptive grids using hundreds to thousands of processors (though smaller simulations may also be run on a scientist's desktop computer). Key software applications have been developed for exploring the fine details of metal containers (encompassing energetic materials) embedded in large hydrocarbon fires. Uintah's underlying technologies have led to novel techniques for understanding large pool eddy fires as well as new methods for simulating fluid-structure interactions. The software is general purpose in nature and the breadth of simulation domains continues to grow beyond the original focus of the C-SAFE initiative.
