Abstract: Large-scale numerical simulations of complex systems are playing an increasingly important role in scientific and engineering applications. The complex, dynamic, and cross-disciplinary nature of such applications poses many challenges and opportunities in their mathematical formulation, computational implementation, and software design, especially for highly parallel computers.
In this talk, I will describe a few challenges and propose some solutions for interfacing diverse components in multi-physics simulations. I will first present a new computational framework, called the face-offsetting method, for propagating dynamically evolving interfaces in numerical simulations. I will then address some spatial and temporal coupling issues in multi-physics simulations to deliver accurate and coherent coupled simulations. I will describe the usage of our techniques in multi-physics simulations and show a few results in large-scale simulations of solid-propellant rockets.
