This is a collection of software modifications created to integrate NanoEngineer-1, PACKMOL and MSI2LMP for the purpose of easily creating molecular dynamics cells. NanoEngineer-1 is a molecular CAD software written by Nanorex and provides the user an easy way to create molecules, while the software modifications allow the user to type atoms using multiple force fields. PACKMOL can generate a random collection of molecules using the molecule templates from NanoEngineer-1 thus providing the initial MD cell. Modifications to PACKMOL allow the atom type data to be passed through to the MSI2LMP software. MSI2LMP creates a LAMMPS input file based on class I or class II force fields. MSI2LMP was modified to use numerically coded force field data generated by NanoEngineer-1. The MMP file format was extended and integrated into all three software applications. http://www.nanoengineer-1.net http://www.ime.unicamp.br/~martinez/packmol/ http://lammps.sandia.gov/

This page is kept for those that want to use the legacy v1 version. For current download, source, and information please go to: https://code.usgs.gov/modflow/mf-owhm ----------------------------------------------------------------------------------------------------------- The One-Water Hydrologic Flow Model (MODFLOW-OWHM, One-Water) is an integrated hydrologic flow (IHM) model that is an enhanced fusion of multiple MODFLOW (MF) versions. While maintaining compatibility with existing MF versions, MF-OWHM includes: linkages for coupled heads, flows, and deformation; facilitation of self-updating models, additional observation and parameter options for higher-order calibrations; and redesigned code for faster simulations. MF-OWHM represents a complete IHM that fully links the movement and use of groundwater, surface water, and imported water for consumption by agriculture and natural vegetation on the landscape, and for potable and other uses.

Rocstar is a multiphysics simulation application designed to do fluid-structure interaction (FSI) across moving, reacting interfaces. Rocstar couples multiple domain-specific simulation packages and disparately discretized domains and provides several simulation-supporting services including conservative and accurate data transfer, surface propagation, and parallel I/O. Rocstar is MPI parallel and routinely executes large simulations on massively parallel platforms. Rocstar was originally developed at the University of Illinois Center for Simulation of Advanced Rockets (CSAR) under Department of Energy ASCI funding. Ongoing development of Rocstar is conducted by Illinois Rocstar LLC with company IR&D and continued DOE SBIR funding.

The collection MICROMECHANICS (micromechanics.zip) includes: (1) lecture notes (microbook.pdf) on the analysis of heterogeneous materials and homogenization, and (2) source codes (microcode.tar.bz2) that accompany the computational exercises in Part II of the notes. Instructions on using the codes are given in the README file of each exercise. Further instructions can be found in the file microcode.tar.bz2. The MATLAB codes are used for visualization, evaluating analytical bounds and estimates as well as in the generation of digital and particulate microstructures. The Fortran codes are based on the finite element method in linear and nonlinear settings, the latter capable of finite deformations with damage. The underlying theory is outlined in the lecture notes. -- İlker Temizer Assistant Professor Department of Mechanical Engineering Bilkent University 06800 Bilkent, Ankara Turkey

Computational Fluid Dynamics (CFD) solver aimed to solve multi-physics problems on unstructured grids (inviscid Euler, Navier-Stokes flows, Heat transfer). F90 based. MPI, cgns, Metis libraries used.

RANSFOIL is a console program to calculate airflow field around an isolated airfoil in low-speed, subsonic, transonic or supersonic regime by numerically solving the Reynolds averaged Navier-Stokes (RANS) equations using mature computational fluid dynamics (CFD) method. As postprocess results, the aerodynamic parameters of the airfoil, e.g., lift coefficient and drag coefficient, can be integrated from the airflow distribution near wall boundary. In addition, the coupling between airflow and heat transfer and the effect of surface roughness on near wall flow are considered by this program, it can be used for engineering calculation of the friction drag and heat transfer coefficients on airfoil surface. RANSFOIL reads coordinates data from a 1D XYZ file which describes the grid points or control points on airfoil as only input, then outputs grid and solution files in 2D PLOT3D format to record grid coordinates and airflow data and a report file to show aerodynamic parameters.

A 2-D inviscid flow and adjoint solver on unstructured triangular grids. It makes use of a vertex-centroid finite volume scheme which is second order accurate.

Atomistic NanoTransport (ANT) comprises a series of codes designed to compute electronic quantum transport with a broad range of applicability in nanoelectronics. ANT.Gaussian (or ANT.G for brevity) relies on the popular quantum chemistry code GAUSSIAN03/09 code with which interfaces in a seamless manner. Straightforwad use of ANT.G include the computation of the zero-bias conductance (or, alternatively, the electrical current under an applied bias voltage) of a variety of nanoscale systems such as molecular bridges or simply metallic atomic contacts as those created with scanning tunneling microscope or break junction techniques. The use of ANT.G may also be naturally extended to the computation of scanning tunneling spectroscopy and the simulation of scanning tunneling and electrostatic force microscopy.
