Abstract

The development of a framework to support smoothed particle hydrodynamics (SPH) simulations of fluid flow and transport in porous media is described. The framework is built using the Common Component Architecture (CCA) toolkit and supports SPH simulations using a variety of different SPH models and setup formats. The SPH simulation code is decomposed into independent components that represent self-contained units of functionality. Different physics models can be developed within the framework by re-implementing key components but no modification of other components is required. The model for defining components and developing abstract interfaces for them that support a high degree of modularity and minimal dependencies between components is discussed in detail.
