Ecological Greenhouse (ees.lanl.gov/ecogreenhouse.shtml)
The EES Ecological Greenhouse currently houses experiments on tobacco growth and native plant survival in marginal soils, as well as studies of nutrient flow between plants and soils. These efforts are collaborations between EES and B Divisions. The greenhouse also houses a growth chamber for small-scale experiments that require control of light, temperature, and humidity. Future studies include research into the dynamics of rapid vegetation shifts that are expected throughout the southwest and are observed in various ecotones, the interfaces between ecosystems. Rapid ecosystem responses to drought, climate change, and/or other disturbances like fire are observed today in northern New Mexico's semiarid landscapes and throughout the world.


Infrasound Monitoring Laboratory
Los Alamos' acoustic-infrasound capabilities extend to frequencies as low as 0.02 Hz (at room temperature this corresponds to a wave length of approximately 10 miles). This capability is part of the Infrasound Calibration Laboratory a component of DOE's Ground-based Nuclear Explosion Monitoring Program. The heart of the infrasound laboratory is a unique chamber that performs calibrations over the passband of 0.02®4.0 Hzãsignal levels that could be affected by several minutes to variations in atmospheric pressure if microphone calibrations were done in isolation.


DSSL - LA Dynamic Stress Stimulation Laboratory for Enhanced Porous Fluid Flow Studies

Scientific Software

CO2-PENS - CO2 Predicting Engineered Natural Systems (co2-pens.lanl.gov)
CO2-PENS is a conceptual and computer model for ensuring safe and effective containment of CO2. It links together physics-based process-level modules that describe the entire CO2 sequestration pathway, starting from capture at a power plant and following CO2 through pipelines to the injection site and into the reservoir. After injection, simulation of CO2 migration continues through the subsurface where it may mineralize, dissolve into brine, or react with wellbore casing or cement. CO2 may leak from the reservoir along wellbores or faults that lead back towards overlying aquifers or the surface. The model can be used to quickly screen sequestration sites or to perform a more detailed site-specific evaluation.
CO2-PENS V1 code: LACC-2012-122


LaGriT - Mesh Generation for Geological Applications (lagrit.lanl.gov)
LaGriT is a software tool for generating, editing and optimizing multi-material unstructured finite element grids; it also maintains the geometric integrity of complex input volumes, surfaces, and geologic data and produces an optimal grid (Delaunay, Voronoi) elements. The data structures used in the code are compact and powerful and expandable to include hybrid meshes (tet, hex, prism, pyramid, quadrilateral, triangle, line), however the main algorithms are for triangle and tetrahedral meshes. The LaGriT tools are used in many projects including ASCEM meshing for Amanzi, Discrete Fracture Networks (DFN), Arctic Permafrost, and Subsurface Flow and Transport models using FEHM and PFLOTRAN. See list of projects at meshing.lanl.gov
LaGriT code: LA-CC-07-38; LACC-2012-084


FEHM - Finite-Element Heat and Mass-Transfer (fehm.lanl.gov)
The numerical background of the FEHM computer code can be traced to the early 1970s when it was used to simulate geothermal and hot dry rock reservoirs. The primary use over a number of years was to assist in the understanding of flow fields and mass transport in the saturated and unsaturated zones below the potential Yucca Mountain repository. Today FEHM is used to simulate groundwater and contaminant flow and transport in deep and shallow, fractured and un-fractured porous media throughout the US DOE complex. FEHM has proved to be a valuable asset on a variety of projects of national interest including Environmental Remediation of the Nevada Test Site, the LANL Groundwater Protection Program, geologic CO2 sequestration, Enhanced Geothermal Energy (EGS) programs, Oil and Gas production, Nuclear Waste Isolation, and Arctic Permafrost.
FEHM V3 code: LA-CC-2012-083


PyFEHM - FEHM with Python (pyfehm.lanl.gov)
PyFEHM is an open-source (LGPL 2.1) Python library that provides classes and methods to support a scripting environment for the subsurface heat and mass transfer, and geomechanics code FEHM. It is inspired by a similar library, PyTOUGH, available for use with the TOUGH2 family of codes.

HIGRAD/FIRETEC- Coupled Atmosphere/Wildfire Behavior Model (ees.lanl.gov/ees16/FIRETEC.shtml)
Recent advances in numerical modeling of small-scale phenomena in the atmosphere are based on two models, the HIgh GRADient applications model (HIGRAD), and a physics-based wildfire-behavior model (FIRETEC). These codes have allowed simulations of atmospheric phenomena at very high spatial resolution on LANL's supercomputers. HIGRAD is coupled to FIRETEC to produce a coupled atmosphere/wildfire behavior model based on conservation of mass, momentum, species, and energy that simulates wildland fire and motions of the local atmosphere. Examples of the tyes of pysical phenomenon of interest are the effects of transient wind conditions, effects of nonhomogeneous terrain, and the effects of nonuniform fuels, and influence of disturbances on fire behavior such ans bark beetle and fuel management.
HIGRAD code: LA-CC-00-45
FIRETEC code: LA-CC-00-46


MARFA - Migration Analysis for Radionuclides in the FAr field (marfa.lanl.gov)
The computer code MARFA (Migration Analysis for Radionuclides in the FAr field) uses an extremely efficient particle-based Monte Carlo method to simulate the transport of radionuclides beneath the surface of the Earth. The algorithm uses non-interacting particles to represent packets of radionuclide mass. These particles are moved through the system according to rules that mimic the underlying physical transport and retention processes. In contrast to the conventional random walk particle tracking algorithm, which use a specified time step and random spatial displacement, the MARFA algorithms use a fixed spatial displacement and a random transit time for the displacement. The use of a fixed spatial displacement makes the code extremely robust and computationally efficient.
MARFA V3.2.3 and V3.3.1 code: LA-CC-11-089


MADS - Model Analysis & Decision Support (mads.lanl.gov)

MC3D is a computational fluid dynamics code for solving the equations associated with convection in Earth's mantle. MC3D solves the momentum and energy equation for an incompressible, zero Reynolds number, infinite Prandtl number fluid in three dimensional Cartesian geometry. The momentum equation is solved using a spectral decomposition and relaxation on each spectral component. The energy equation is solved using finite difference methods with a tensor diffusion correction. MC3D is parallel and runs on Unix and Linux cluster computers. A unique feature of MC3D is an implementation of mobile surface plates which allows one to study the dynamic interaction of mantle convection and plate tectonics.


PFLOTRAN - Parallel code for Flow and Reactive Transport (www.pflotran.org)
PFLOTRAN is an open source, state-of-the-art massively parallel multiphase, multicomponent and multiscale subsurface flow and reactive transport code. Parallelization is achieved through domain decomposition using the PETSc libraries. PFLOTRAN has been developed from the ground up for parallel scalability and has been run on up to 218 processor cores with problem sizes up to 2 billion degrees of freedom. Currently PFLOTRAN can handle a number of surface and subsurface processes including Richards equation, two-phase flow involving supercritical CO2, and multicomponent reactive transport including aqueous complexing, sorption and mineral precipitation and dissolution, on structured as well as unstructured grids. A unique feature of the code is its ability to run multiple input files and multiple realizations of permeability and porosity fields simultaneously on one or more processor cores per run. Additional capabilities include multiple interacting continuum method and discrete fracture network approach for modeling flow and transport in fractured media.
