Welcome to GDSA Framework

GDSA Framework Software


PFLOTRAN is an open-source, state-of-the-art, massively parallel subsurface flow and reactive transport simulator, and the engine of GDSA Framework. PFLOTRAN solves a system of generally nonlinear partial differential equations describing multiphase, multicomponent, and multiscale reactive flow and transport in porous materials.

The Dakota project delivers both state-of-the-art research and robust, usable software for optimization and UQ. Broadly, the Dakota software’s advanced parametric analyses enable design exploration, model calibration, risk analysis, and quantification of margins and uncertainty with computational models. The Dakota toolkit provides systems analysis methods for desktop or high-performance computing, including optimization, uncertainty and sensitivity analysis, and parameter estimation.

ParaView is an open-source, multi-platform data analysis and visualization application. ParaView users can quickly build visualizations to analyze their data using qualitative and quantitative techniques. The data exploration can be done interactively in 3D or programmatically using ParaView’s batch processing capabilities.

dfnWorks generates three-dimensional discrete fracture networks (DFNs), simulates flow and transport with PFLOTRAN, performs particle tracking, and offers graph analysis methods. Developed at Los Alamos National Laboratory, it has been used to study flow and transport in fractured media at scales ranging from millimeters to kilometers.
