The Modular System for Shelves and Coasts (MOSSCO) is a coupling framework for Earth System Models. It helps users to integrate their own numerical models with other developments. Quick Start: git clone git://git.code.sf.net/p/mossco/setups mossco-setups git clone git://git.code.sf.net/p/mossco/code mossco-code cd mossco-code cat QuickStart.md or read online https://sf.net/p/mossco/code/ci/master/tree/QuickStart.md Beware: this is alpha software, expect trouble! ------------------------- Better, read the full documentation online http://www.mossco.de/doc or make it yourself make doc acroread doc/mossco_documentation.pdf ---------------------- Why MOSSCO? MOSSCO, the "Modular System for Shelves and Coasts" is a framework for coupling processes or domains that are originally developed in standalone numerical models. The software MOSSCO implements this infrastructure in the form of a library of components and couplers, and of example coupled application.

UPDATE: As of March 2023, the CFDTOOLS project has moved its public repository to NASA's official organization on GitHub: https://www.github.com/nasa/cfdtools While this repository will remain available, it will no longer receive updates or be monitored for issues. Please see the link above for latest releases and issue status. ---- The CFD Utility Software Library (previously known as the Aerodynamics Division Software Library at NASA Ames Research Center) contains nearly 30 libraries of generalized subroutines and close to 100 applications built upon those libraries. These utilities have accumulated during four decades or so of software development in the aerospace field. David Saunders and Robert Kennelly are the primary authors, but miscellaneous contributions by others are gratefully acknowledged.

An all-electron full-potential linearised augmented-planewave (FP-LAPW) code. Designed to be as developer friendly as possible so that new developments in the field of density functional theory (DFT) can be added quickly and reliably.

SWASH is a general-purpose numerical tool for simulating unsteady, non-hydrostatic, free-surface, rotational flow and transport phenomena in coastal waters as driven by waves, tides, buoyancy and wind forces. It provides a general basis for describing wave transformations from deep water to a beach, port or harbour, complex changes to rapidly varied flows, and density driven flows in coastal seas, estuaries, lakes and rivers.

The Ocean Land Atmosphere Model (OLAM) is a new global general circulation/climate prediction model that will allow to “nest down” to any desired resolution using a flexible mesh refinement technique that works on either triangular or hexagonal g

The evTools package provides tools to manipulate and display output from the binary stellar-evolution code ev (also known as STARS and TWIN).

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.

Zgoubi is a ray-tracing code. Since 1972 it pushes charged particles around accelerators and along beam lines, by step-wise resolution of the Lorentz force equation - and their spins by resolution of Thomas-BMT differential equation. Zgoubi is used for charged particle and beam dynamics simulations, and for accelerator and beam line design. It can simulate hadron and lepton beam and polarization dynamics in a large variety of accelerators (storage ring, synchrotron, cyclotron, microtron, linear and scaling FFAG, multi-pass ERL, etc.) and optical systems (magnetic and electrostatic optical components and beam lines, time-of-flight and mass spectrometers, etc.). It includes built-in fitting procedures, with a wide variety of constraints. It includes synchrotron radiation Poynting vector tracking, synchrotron radiation energy loss, space charge modeling, several Monte Carlo procedures.

Please go to project home (https://hypeweb.smhi.se/model-water/) or wiki-pages (http://hype.smhi.net/wiki/doku.php?id=start) for more information. The hydrological model HYPE is developed at the Swedish Meteorological and Hydrological Institute (SMHI). The model simulates water, nutrients and other substances in small and large river catchments. Included in the project is HYSS, which is needed to run the model. It handles input and output and the simuation over time.

Within the SIROCCO suite of numerical tools, the purpose of SDAP is to provide a flexible platform to carry out multivariate assimilation of geophysical data in a numerical model. The program is multi-grid (finite differences or finite elements), multi-algebra (plug-in analysis kernels), multi-model (simple standardized interface). The program supports reduced-order data assimilation methods, as well as Ensemble assimilation approaches such as the Ensemble Kalman Filter. Recent additions include extensions towards simultaneous assimilation and downscaling (AMICO project), and a toolbox for ensemble assessment (SCRUM project). *Please note that due to frequent updates the code is only available via the svn repository. Please get in touch with us to obtain access.*

We are proud to introduce version 5 of CAMPARI. We have added a number of new features, most notably a Python interface for interpreting user-supplied code (with the help of ForPy), a novel trajectory storage standard (with the help of libpqxx/PostgreSQL), and a module for performing transition path theory. Naturally, CAMPARI continues to provide the reference implementation of the ABSINTH force field paradigm and implicit solvation model. CAMPARI is a joint package for performing and analyzing molecular simulations, in particular of systems of biological relevance. It focuses on a wide availability of algorithms for (advanced) sampling and is capable of combining Monte Carlo and molecular dynamics in seamless fashion. CAMPARI offers the user a very high level of control over all implemented features. For more information and features, please refer to the project's homepage at http://campari.sourceforge.net/V5
