TITLE: Data Transfer and Interface Propagation in Multicomponent
Simulations
ABSTRACT
This talk addresses various computational problems arising from
interfacing software components in three-dimensional multicomponent
simulations. Typically, the computational domain for each physical
component in such a simulation is discretized using a volume mesh, and
the meshes for adjacent domains abut each other at a common interface
surface. In general, the two discretizations of such an interface from
different components differ both topologically and geometrically, and
data must be exchanged between these disparate interface meshes. We
address the problems of correlating disparate interface meshes (mesh
association), computing their common refinement (mesh overlay), and
transferring data between them in a numerically accurate and physically
conservative manner. In many cases, the interface evolves due to
various processes, such as burning, erosion, or deformation, and we
also consider the problem of propagating the interface surface
dynamically as the components evolve over time.
