ERmod (Energy Representation Module) is a program to calculate the solvation free energy based on the energy representation method (J. Chem. Phys. 113, 6070 (2000)). The program allows users to calculate the solvation free energy to arbitrary solvents, including inhomogeneous systems, and can run in cooperation with state-of-art molecular simulation software, such as LAMMPS, GROMACS and/or AMBER.

Please go to project home (https://hypeweb.smhi.se/model-water/) or wiki-pages (http://www.smhi.net/hype/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.

SWAN is a third-generation wave model, developed at Delft University of Technology, that computes random, short-crested wind-generated waves in coastal regions and inland waters.

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.

Fully automatic h, p, and hp-adaptive finite element package supporting different physics modes.

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.*

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.

FFTW++ is a C++ header class for the FFTW Fast Fourier Transform library that automates memory allocation, alignment, planning, wisdom, and communication on both serial and parallel (OpenMP/MPI) architectures. In 2D and 3D, hybrid dealiasing of convolutions substantially reduces memory usage and computation time. Wrappers for C, Python, and Fortran are included.

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.
