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.

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/

Cantera is a suite of object-oriented software tools for problems involving chemical kinetics, thermodynamics, and/or transport processes. It can be used from MATLAB, Python, C++, or Fortran.

Computational electromagnetics software. Uses surface Method of Moments, enhanced by using the Multilevel Fast Multipole Method. Code is parallelized and runs on laptops, desktops and clusters. The code precision is adjustable, it is fast and uses little memory. CFIE is used for closed surfaces, and EFIE for open PEC surfaces. Can function on GMSH, GiD and ANSYS meshes.

PySCeS is the Python Simulator of Cellular Systems. For a network of coupled reactions it does a stoichiometric matrix analysis, calculates the time course and steady state, and does a complete control analysis.

This compact function parser module written in Fortran95 is intended for applications where a set of Fortran-style mathematical expressions is specified at runtime and is then evaluated for a large number of variable values.

This site hosts the source code for C++ version of the Broker for SBW, NOM module, advanced simulation suite, analysis applications and model editors.

Hermes -- a set of libraries and tools for the support of scientific simulation and data archival.

SMMP (Simple Molecular Mechanics for Proteins) is a program library for protein simulations with an emphasis on advanced Monte Carlo algorithms. It includes various force fields to calculate the energy of a protein and protein-protein interactions.

EPx is a "modified version of EnergyPlus v. 7 or 8", a fork of the open-source building energy simulation engine developed by the US Department of Energy. This project also contains the canonical open-source releases of the unmodified EnergyPlus source code.

Do you work with chemical reactors? Are you curious about them? ASALI is the open-source code that you are looking for. Chemical reactor models, transport/thermodynamic properties of gases, equilibrium calculations. ASALI couples all these features with an user friendly graphical interface. Modeling chemical reactors has never been so easy.

PDSTRIP is a hydrodynamic strip code for seakeeping. It computes ship motions for monohulls including sailing boats. PDSTRIP has been abandoned by its initiators, who do not wish to be contacted with use questions. The position of maintainer is vacant.

Tahoe is a research-oriented platform for the development of numerical methods and models for the simulation of complex material behavior.

DBSolveOptimum is a stand-alone software tool for the construction and analysis of mathematical models of biological systems. It is a succession and extension of DBSolve 5 and DBSolve 7, which were popular tools for systems biology. In addition to the capabilities of these software packages, DBSolveOptimum is implemented with new tools for extended data analysis and multiple simulations, which are important for simulation of virtual clinical trials and application of modern modeling techniques, like quantitative systems pharmacology, to problems arising in drug research and development. By this time, DBSolveOptimum has been successfully tested and applied for the development and analysis of both systems pharmacology and conventional PK/PD models of drugs. It is free for academic and industrial use. http://www.ncbi.nlm.nih.gov/pubmed/20698988

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.
