AMANZI: The Multi-Process HPC Simulator

Build Status

BACKGROUND

The objective of the Advanced Simulation Capability for Environmental Management (ASCEM) is to develop a state-of-the-art scientific approach and tool for understanding and predicting contaminant fate and transport in natural and engineered systems. The modular and open source high performance computing tool will facilitate integrated approaches to modeling and site characterization that enable robust and standardized assessments of performance and risk for EM cleanup and closure activities. In addition, the integrated toolset will incorporate capabilities for predicting releases from various waste forms, identifying exposure pathways, performing dose calculations, conducting systematic uncertainty quantification.

Amanzi, the Multi-Process HPC Simulator is a critical component of this approach and tool. Amanzi will be a highly modular and extensible computational engine for simulations of flow and reactive transport. Currently, it is capable of simulating transient saturated and variably saturated (Richards) flows, transport with non-grid-aligned dispersion and a variety of reactions. In the future it will include non-isothermal, multi-phase multi-component, geo-mechanical, and surface water models. To achive this ambitious goal we are building Amanzi as a grass-roots collaboration of an emerging broader community of geoscienists, computational and computer scientists, and applied mathematicians. This broader community is leveraging its extensive experience, existing capabilities, and untapped advances from their areas of expertise to develop Amanzi.
