RSM (Radiation Spectrum Method) is a 2D rigorous tool to solve the Maxwell equations for the propagation of light in integrated optics or photonics devices. It makes use of an EigenMode Expansion method (EME) to solve the electromagnetic problem. This software running on Windows and MacOS comes with a GUI that permits to define with the aid of files or scripts the arbitrary and complex geometry of the waveguide. Of that way any waveguide geometry can be handled. Several plots are available : refractive index plot, field propagation plot and modes spectrum plot. This permits, with the interpretation of the guided and radiation modes spectrum, a physical understanding of the propagation mechanisms in the integrated optical device under evaluation. ...

...It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub. See https://github.com/gridlab-d/gridlab-d. Issue tracking is handled by GitHub. See https://github.com/gridlab-d/gridlab-d/issues.

VASPMO aims at visualizing wavefunctions (or molecular orbitals) from VASP calculations. It reads VASP's output files PROCAR and CONTCAR, and exports an *.out file in Gaussian's output format, which can be visualized by many popular visualization tools, such as JMol, Molekel, Chemcraft, Gabedit and Molden, etc. These tools can further generate *.cube files, which can be visualized by an even wider range of...

...EVAlgebra support space dimension from 1 to 4 with arbitrry signature. It is fully documented at evalgebra.org. You may write your own scripts to resolve specific problem.

Interactive Web Physics is a Java, Web-based animation and problem designer tool. Anyone can quickly design mathematics or physics animations and simulations that run in a web browser. Unlike other solutions, no knowledge of programming is required.

Keywords: -simultaneously fit several SAXS and SANS data sets with polydisperse (Schultz-Zimm or Gaussian distribution f(R)) spherical core-shell-shell nanoparticles -analytical expressions are used for from factor F(Q) and its integral over f(R), no numerical integration required -absolute units -Mathematica is required via console (MathKernel) -Mathematica's local and global optimizers (simulated annealing, differential evolution, Nelder-Mead, ...) can be used -range for fit parameters and further constraints between fit parameters are possible -Monodisperse(!) hard sphere structure factor can be used, too -long computation times (depending on problem size and amount of constraints) from hours to a few days are possible -non-parallelized code

Discrete Dipole Approximation Project, is a software package designed to solve the Discrete Dipole Problem by the Discrete Dipole Approximation (DDA) method. This software is desgined to be plugin operated allowing for easy implimincation of new solver methods to improve the efficienty of the code. The plugin support also allow the program to write its output in multiple formats and structures defined by plugins.

...LIME is intended to be especially useful when separate computer codes (which may be written in any standard computer language) already exist to solve different parts of a multiphysics problem. LIME provides the key high-level software (written in C++), a well defined approach (with example templates), and interface requirements to enable the assembly of multiple physics codes into a single coupled-physics simulation code. To achieve its flexible lightweight design objectives, LIME 1.0 requires that some amount of customized software be written each time a new multiphysics application is created. ...

DIFFR is a menu-driven graphical software whereby the problem of a plane wave diffraction on a rough surface can be solved using several numerical and approximate methods.

CFD scientific software. Provides simulation of 3D CFD problem based on Quasi-Gas Dynamics approach with radiation processes token into account. Lots of spectral intervals are considered. Parallel MPI/OpenMP-based implementation is provided.

REMD toolkit is designed as a C++ framework to build a replica-exchange molecular dynamics (REMD) program, suitable for solving the multiple-minima problem that prevents accurate estimation of thermodynamical properties.
