DAPS4e is an updated version of a Fortran code by John Renzi for design and analysis of monocoque and ring-stiffened circular cylindrical shells. The following failure modes are considered: • Shell stresses and displacements at mid-bay and ring-frames. • Ring-frame stress. • Axisymmetric collapse (AC). • Elastic and Inelastic Interbay Buckling. (EIB and IIB). • Elastic and Inelastic Monocoque Instability (EMI and IMI). • Elastic and Inelastic General Instability (EGI and IGI). • Ring-Frame Elastic Instability analysis (EFI). Solutions compare favorably with DTMB experimental results. DAPS4e’s IO is managed through a Visual Basic user form. Pre/post processing is done using linked macro-enabled Excel spreadsheets. The file DAPS4e.zip includes: • DAPS4e.3 executable and Fortran 77/95 source code. • Visual Basic user form and its 2017 Visual Studio project code. • Excel spreadsheet pre/post processors. • Comprehensive technical documentation.

GeoSolid3D produces 3D geologic solid models, incorporated into the aquifer and confining units of the USGS ground water models, Modflow and Sutra. Uses GIS data of DEMs, geologic maps, and maps of river, watershed, recharge, and aquifer parameters.

Although many potential applications exist in chemistry and material science, software to allow the general application of de novo structure-based design methods in supramolecular chemistry was non-existent. To address this limitation we created HostDesigner, a code that builds and evaluates millions of molecules in minutes. This command line executable builds 3D molecular structures by covalently connecting user-defined input fragments with pre-computed hydrocarbon fragments from a library. The results are ranked with respect to desired geometric constraints defined by the user. See the User's Manual for further details including a list of literature citations for example applications. Download includes User's Manual, HostDesigner 4.3 source code (in Fortran), data files, example input, HDViewer executables for MacOS, Linux, and Windows, and mengine source code (in C). HostDesigner was developed and posted by author Dr. Benjamin P Hay

Ichnaea is a set of tools that aid in collecting and tracking parameters and timings for parallel applications. The Performance Modelling Timing Module, PMTM, is a library that wraps system timing calls to abstract these from code developers and aid portability. It also has functionality to store parameters and print those, along with the timing information to a comma separated variable file. The Performance Modelling Analysis Tool, PMAT, is coming soon. This is able to read in and store the outputs from PMTM and produce some graphs based on user-defined criteria. Documentation found in the Wiki. As of March 2015, main development has been switched to the UK Mini-Application Consortium Github page. Work on PMTM from the unreleased version 2.6.0 can be found here: https://github.com/UK-MAC/PMTM Work on PMAT version 3 will be commencing shortly here: https://github.com/UK-MAC/PMAT Tarballs of releases will continue to be available here.

XML Parser for Fortran. Handles XML and similar structured files. The library provides access (read and write) via a linked list. This is conceptual different from the SAX approach. The data can be held and 'browsed' in memory.

This library contains the parametrization of pp->gamma cross section functions based on Phys.Rev. D90 (2014) 12, 123014 (astro-ph/1406.7369) work. The functions are written in Python, Fortran and Matlab. Please, if you use this library DO NOT reference to this webpage, instead reference to Phys.Rev. D90 (2014) 12, 123014 (astro-ph/1406.7369), "Parametrization of gamma-ray production cross-sections for pp interactions in a broad proton energy range from the kinematic threshold to PeV energies" by Ervin Kafexhiu, Felix Aharonian, Andrew M.

Loglan'82 is a programming language conceived for object and distributed programming. It has many features that make Loglan'82 a tool surpassing other programming languages: * It enjoys a unique safe and efficient system of managing objects, see [[Safe dealocation]], * It offers modules of classes (__class__), moreover it allows to declare modules of cooperating objects i.e. **coroutines** and modules of threads ('''process'''). One can create not only objects of classes, but also objects of coroutines with their ''fibres'' and objects of processes, aka agents with their *threads*. * Virtual machines of Loglan may connect (through internet) in a virtual, multiprocesorr computer.This allows to distribute a computation of a program between processors in a controlled way. * Objects of processes (agents) can be alocated on different nodes of a network of virtual machines or on the same machine.

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.

NESSIE is a modern first-principle calculation software that can adequately address the need for ever-higher levels of numerical accuracy and high-performance in large-scale electronic structure simulations, as well as pioneer the fundamental study of quantum many-body effects in a large number of emerging nanomaterials. NESSIE is an electronic structure code that uses a real-space FEM discretization and domain-decomposition (DD) to perform all-electron ground-state DFT and real-time excited-state TDDFT calculations. The code is written to take advantage of multilevel parallelisms of the FEAST eigenvalue solver to target systems containing many distributed-memory compute nodes. The real space mesh is generated using the software tetgen.

Nonlinear Krylov Acceleration (NKA) is a method for accelerating the convergence of fixed-point (Picard) iterations. Many Newton-like and inexact Newton methods are fixed point iterations. The NKA project provides the canonical implementation of the method for several programming languages. The black-box accelerator is simple to integrate into existing code. Placed in the iteration loop, it observes the sequence of solution updates and replaces them with improved updates using information it has gleaned from previous solution iterates. It was only recently recognized (2011) that NLK is essentially equivalent to Anderson Acceleration for a specific choice of mixing parameter. NLK was independently devised in the late 1980's using a very different approach, and though it leads to the same algebraic method, NLK's organization is somewhat different, and arguably superior. The NLK approach also provides clear rationale for the proper choice of Anderson's arbitrary mixing parameter.

An open source code for the analysis of electronic excited states: Natural Transition Orbitals; Detachment and Attachment Density Matrices; Quantum Chemical Charge-Transfer Descriptors. The code is intended to postprocess Gaussian 03 and 09 outputs. Important Note: A new release with better compilation option has been released on November the 9th 2015. We strongly advise to use this one since the previous option may have led to some unexpected bugs.
