C14014 QUIC v. 6.x The Quick Urban & Industrial Complex (QUIC) Dispersion Modeling System is a fast response urban dispersion model that runs on a laptop.

QUIC is comprised of a fast-running 3D wind field model called QUIC-URB, a computational fluid dynamics wind solver QUIC-CFD, a transport and dispersion model called QUIC-PLUME, a pressure solver, QUIC-PRESSURE, and graphical user interface called QUIC-GUI.  Airborne particle and gaseous contaminant dispersion can be computed on building to neighborhood scales in tens of seconds to tens of minutes.  QUIC will never give perfect answers, but it will account for the effects of buildings in an approximate way and provide more realism than non-building aware dispersion models.

QUIC produces high-resolution 3-D mean wind and concentration fields around buildings, in addition to deposition on the ground and building surfaces.  It has options for different release types, including point, moving point, line, area, and volumetric sources, as well as dense gas, explosive buoyant rise, multi-particle size, bio-slurry, and two-phase releases. Other features include indoor infiltration, a pressure solver, a nested grid capability, vegetative canopies, and population exposure calculations.
The QUIC-URB wind solver is an empirically-based diagnostic wind model.  Initial flows around the buildings are computed using various empirical relationships based on the building height, width, and length, as well as the spacing between buildings and then mass consistency constraints are applied to the flow field to satisfy mass conservation. The QUIC-CFD wind solver solves the Navier-Stokes fluid dynamics equations around buildings.  It is slower than QUIC-URB, but faster than traditional computational fluid dynamics codes because of a combination of the use of artificial compressibility, simplified turbulence scheme, and optimized Fortran programming.  The QUIC-PLUME dispersion model is an "urbanized" Lagrangian random-walk code that tracks the movement of gases and aerosols as they disperse through the air.  It uses the mean wind field computed by the wind solver and produces the turbulent dispersion of the airborne contaminant using random-walk equations with additional drift terms appropriate for the inhomogeneous nature of turbulence around buildings. The normal and shear stresses and turbulent dissipation are determined based on similarity theory, gradient transport and a novel non-local mixing formulation that approximates the turbulent mixing that occurs in building cavities and street canyons.  Numerous capabilities have been added to QUIC-PLUME in order to handle dense gas, buoyant gas, particle and droplet dispersion and deposition around buildings and infiltration into buildings. QUIC-PRESSURE utilizes the mean wind output from QUIC-URB and computes a 3D pressure field around buildings based on a Poisson pressure solver. 

The QUIC-GUI graphical user interface allows the user to easily set up problems, run the codes, and visualize results.  The QUIC-GUI is made up of several components, including a City-Builder, a Met-Builder, a Source Term GUI, Random-Walk Parameters Set-Up, and 3D Visualization GUI, a Data Extractor, and a Population Exposure Calculator. This technology is available for exclusive or nonexclusive license based on the potential licensee’s intended application of the software and ability to meet Los Alamos National Security license requirements.  Inquiries to license software should be directed to software@lanl.gov.

C14012 QUIC-URB Wind Solver v. 6.x QUIC-URB is comprised of a fast-running 3D wind field model that produces high-resolution 3-D mean wind fields around buildings.The QUIC-URB wind solver is an empirically-based diagnostic wind model.  Initial flows around the buildings are computed using various empirical relationships based on the building height, width, and length, as well as the spacing between buildings and then mass consistency constraints are applied to the flow field to satisfy mass conservation.  Logic has been developed regarding in what order to implement the flow algorithms and whether or not to overwrite or modify competing building flow zones in order to obtain accurate wind flow results in densely-built urban areas.  Formulations for rectangular, cylindrical, and other polygonal shaped-buildings have been derived so that the wind solver can be applied to real-world cities.  Parameterizations for the effect of forest canopy drag have been included as well.   This technology is available for exclusive or nonexclusive license based on the potential licensee’s intended application of the software and ability to meet Los Alamos National Security license requirements.  Inquiries to license software should be directed to software@lanl.gov. 11/12/2013
13-006 VPSC-ABAQUS UMAT The VPSC-ABAQUS UMAT is an user-defined material subroutine for the commercial ABAQUS-Standard Finite Element package. The UMAT is based on the ViscoPlastic Self-Consistent (VPSC) formulation and the corresponding stand-alone VPSC code. The VPSC is a multipurpose polycrystal plasticity FORTRAN code, based on the knowledge of the mechanisms of slip and twinning that are active in single crystals of arbitrary symmetry and the texture of the aggregate. VPSC can be used to predict the effective stress-strain response, texture evolution, anisotropy, etc., and as a predictive tool for parameter identification, interpretation of experimental results and multiscale calculations, for academic and industrial applications to metallic, geologic and polymeric materials. 1/23/2013
