Abstract: Object-oriented platforms developed for the numerical solution of
PDEs must combine flexibility and reusability, in order to ease the integration
of new functionalities and algorithms. While designing similar frameworks, a
built-in support for high performance should be provided and enforced
transparently, especially in parallel simulations. The paper presents solutions
developed to effectively tackle these and other more specific problems (data
handling and storage, implementation of physical models and numerical methods)
that have arisen in the development of COOLFluiD, an environment for PDE
solvers. Particular attention is devoted to describe a data storage facility,
highly suitable for both serial and parallel computing, and to discuss the
application of two design patterns, Perspective and Method-Command-Strategy,
that support extensibility and run-time flexibility in the implementation of
physical models and generic numerical algorithms respectively.
