The Computational Earth Science Group provides innovative simulation capabilities to integrate knowledge and observational data, explain complex processes, and predict future conditions and states of earth and environmental systems. We apply our capabilities to solve nationally important problems in the environment, energy, and national security sectors. Through our focus on subsurface flow and transport processes, we develop and apply models to address challenges in predicting radionuclide migration in fractured and porous media, understanding the complex interaction of non-isothermal, multiphase flow processes for such endeavors as geologic carbon sequestration, and developing strategies for geothermal and electrokinetic energy production. Our R&D 100 winning HiGrad/FireTec hydrodynamic code provides the basis for analysis of hurricane intensification with the incorporation of lightning data, wildfire and urban firestorm propagation studies, and wind energy assessments focusing on interference and interactions between multiple turbines as well as the material weathering of wind blades. Moving further up in elevation, we develop first-principle modeling capabilities to simulate Electromagnetic Pulse (EMP) signatures as might be seen from satellites in order to characterize security threats and filter lightning signatures. We also integrate capabilities in geologic characterization, GIS simulation, policy analysis, and remote sensing through geospatial, infrastructure, and integrated assessment modeling for projects associated with environmental characterization, energy development, and resource impact assessment.
EES-16 has a rich history in high performance computing. We have recently ported HiGrad/FireTec to LANL's novel heterogeneous architecture, petaflop per second RoadRunner architecture. Our PFLOTRAN code has achieved groundbreaking benchmarks, using over 130,000 cores on the leadership-class Jaguar computer at ORNL for groundwater contaminant transport simulations. Recently, EES-16 has established leadership roles on the new ASCEM (Advanced Simulation Capability for Environmental Management) Project, a multi-lab, multi-year initiative to develop high performance simulation capabilities to address the complex legacy challenges DOE-EM faces in remediating and closing sites in challenging hydrogeologic systems with challenging waste materials.
