Abstract
Multiphysics simulations are playing increasingly important roles
in computational science and engineering for applications ranging
from aircraft design to medical treatments. These simulations
require integration of techniques and tools from multiple
disciplines, and in turn demand new advanced technologies to
integrate independently developed physics solvers effectively. In
this paper, we overview some numerical, geometrical, and system
software components required by such integration, with a concrete
case study of detailed, three-dimensional, parallel rocket
simulations involving system-level interactions among fluid, solid,
and combustion, as well as subsystem-level interactions. We package
these components into a software framework that provides
state-of-the-art, common-refinement based methods for transferring
data between potentially nonmatching meshes, novel and robust
face-offsetting methods for tracking Lagrangian surface meshes, as
well as integrated support for parallel mesh optimization,
remeshing, algebraic manipulations, performance monitoring, and
high-level data management and I/O. From these general, reusable
framework components we construct domain-specific building blocks
to facilitate integration of parallel, multiphysics simulations
from high-level specifications that are easy to read and can also
be visualized graphically. Through a non-intrusive integration
framework, these building blocks are integrated with independently
developed fluid, solid, and combustion codes that may use different
types of meshes (structured vs. unstructured), discretization
methods (finite element or finite volume), and different
programming languages (Fortran 90 or C++). Through examples, we
demonstrate the flexibility of our framework and its components.
