[edit] Support Architecture for Large-Scale Subsurface Analysis (SALSSA)

Many subsurface flow and transport problems of importance today involve coupled non-linear flow, transport, and reaction in media exhibiting complex heterogeneity. In particular, problems involving biological mediation of reactions and/or mineral precipitation/dissolution fall into this class of problems. Researchers at PNNL have developed a hybrid multi-scale modeling framework that integrates models with diverse representations of physics, chemistry and biology at different scales (sub-pore, pore and continuum). The modeling framework takes advantage of advanced computational technologies including parallel code components using the Common Component Architecture (CCA). A pore scale Smoothed Particle Hydrodynamics (SPH) model has been built within the CCA framework. The Support Architecture for Large-scale Subsurface Simulation and Analysis (SALSSA) software framework addresses the macro modeling processes such as running simulations and analyzing their results. SALSSA integrates workflow, data management, and visualization supporting the development, validation, and use of the SPH model.
