Dynamic Interfaces in Parallel Numerical Simulations

Xiangmin (Jim) Jiao

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-component simulations. I
will describe the usage of our techniques and show a few results in
large-scale rocket simulations.

Dr. Jiao received his Ph.D. from University of Illinois at
Urbana- Champaign (UIUC) in 2001. He then worked as a Research
Scientist at (UIUC), where he was the primary author of a few key
numerical and geometric algorithms and a software integration
framework of the DOE Center for Simulation of Advanced Rockets (CSAR).
He is currently a Visiting Assistant Professor the College of
Computing at Georgia Institute of Technology.
