“…The algorithm is a finite volume, multi-material CFD code based on the ICE (Implicit, Continuous-fluid, Eulerian) method. The ICE implementation used in this study is well developed and documented [22][23][24]. The code is three-dimensional, fully compressible, unsteady, and capable of modeling variable fluid properties, fluid-structure interactions, and chemical reactions.…”

“…A good example of a production-strength multiphysics framework is Uintah (Parker, 2006;Parker et al, 2006), a set of software components and libraries that facilitate the solution of partial differential equations on structured adaptive mesh refinement grids using hundreds to thousands of processors (Luitjens et al, 2008). Uintah employs an abstract task graph representation to describe computation and communication.…”

We consider multiphysics applications from algorithmic and architectural perspectives, where "algorithmic" includes both mathematical analysis and computational complexity and "architectural" includes both software and hardware environments. Many diverse multiphysics applications can be reduced, en route to their computational simulation, to a common algebraic coupling paradigm. Mathematical analysis of multiphysics coupling in this form is not always practical for realistic applications, but model problems representative of applications discussed herein can provide insight. A variety of software frameworks for multiphysics applications have been constructed and refined within disciplinary communities and executed on leading-edge computer systems. We examine several of these, expose some commonalities among them, and attempt to extrapolate best practices to future systems. From our study, we summarize challenges and forecast opportunities.

“…The core of Uintah is a sophisticated computational framework that can integrate multiple simulation components, analyze the dependencies and communication patterns between them, and execute the resulting multi-physics simulation [23]. Uintah utilizes an abstract representation (called a task-graph) of parallel computation and communication to express data dependencies between multiple physics components.…”

It is well known that the violence of slow cook-off explosions can greatly exceed the comparatively mild case burst events typically observed for rapid heating. However, there have been few studies that examine the reaction violence as a function of applied heat flux that explore the dependence on heating geometry and device size. Here we report progress on a study using the Uintah Computation Framework, a high-performance computer model capable of modeling deflagration, material damage, deflagration to detonation transition and detonation for PBX9501 and similar explosives. Our results suggests the existence of a sharp threshold for increased reaction violence with decreasing heat flux. The critical heat flux was seen to increase with increasing device size and decrease with the heating of multiple surfaces, suggesting that the temperature gradient in the heated energetic material plays an important role the violence of reactions.
