Multi-Component Systems FUEL CELLS

General Features Multi-Component Sharp Interfaces Different material properties Different physical processes Reactive Interfacial chemistry Volume chemistry

Single Component Model Multi-Physics Multi-Domain Multi-Processor DRAWBACK: Impossible to represent components

Multi-Component Model One component for each element. Many elements for each component.

Implementation Meta-Model: UML Solver: C++/MPI Pre/Post Processor: Java/Java3D

Features and Advantages Component represents a physical entity Model represents a physical law

Features and Advantages Straightforward representation of multi- component systems Flexible solution cycles: Model-by-model Component-by-component
