The density-functional toolkit, DFTK for short, is a collection of Julia routines for experimentation with plane-wave density-functional theory (DFT). The unique feature of this code is its emphasis on simplicity and flexibility with the goal of facilitating algorithmic and numerical developments as well as interdisciplinary collaboration in solid-state research.

JUDI is a framework for large-scale seismic modeling and inversion and is designed to enable rapid translations of algorithms to fast and efficient code that scales to industry-size 3D problems. The focus of the package lies on seismic modeling as well as PDE-constrained optimization such as full-waveform inversion (FWI) and imaging (LS-RTM). Wave equations in JUDI are solved with Devito, a Python domain-specific language for automated finite-difference (FD) computations. JUDI's modeling operators can also be used as layers in (convolutional) neural networks to implement physics-augmented deep learning algorithms thanks to its implementation of ChainRules's rrule for the linear operators representing the discre wave equation.

This course aims to cover state-of-the-art methods in modern parallel Graphical Processing Unit (GPU) computing, supercomputing and code development with applications to natural sciences and engineering.

I've been trying to develop an idea of a project, but the wide range of possibilities with all their outcomes, cons and pros and whatnot got my mind overloaded. There was no way I could keep or process that much information with my bare mind. So, I've checked the mind mapping tools available in the market, both free and commercial ones, yet they were either clunky or overkilling for my needs. Thus, I've made my own thing, and decided to share it with everyone who might find it useful for...

The Coastline Evolution Model (CEM), originally developed by Ashton et al. (2001), Ashton and Murray (2006) and Valvo et al. (2006), is a reduced complexity, one-line sediment transport model that simulates the evolution of coastlines via wave-driven alongshore sediment transport. The original CEM has no Graphical User Interface (GUI) and does not provide graphical visualisations during model runs. The modified version given here includes these features. This project forms part of a wider research project and further developments on this model are anticipated.

...It can create a 2D plane of charge densities or create a 1D representation of the charge densities along a given line, in both cases it can also export the graphical representations to various image formats. The program can import various file formats such as space 3D grids of charge density values, created in a quantum chemistry programs Gaussian, Crystal and VASP. Wave functions in the form of .wfn files are also supported and serve, not only to compute the charge densities, but also laplacian as the sum of second partial derivatives of charge density. Thanks to the cooperation with the author of Jana2006 Vaclav Petricek, the program supports also multipoles obtained by measurements on a diffractometer. ...

OVATION Prime is a seasonal model of the diffuse, monoenergetic, proton, and wave aurora. The OVATION Prime model is written in IDL and was developed at the Johns Hopkins Applied Physics Laboratory (JHU-APL) by Patrick Newell and co-workers. This current version includes updates to the retrospective and real time components, several efficiency enhancements and a user configuration as implemented by Rob Redmon and Janet Machol of NOAA.

...A magnetic flux situated between the two slits allows demonstration of the Aharonov–Bohm effect. Simulations with short de Broglie wavelengths illustrate the classical limit of quantum mechanics. Because of the universality of wave phenomena, this program can also demonstrate the geometrical-optics limit of wave optics for small wavelengths.

The purpose of this program is to plot the waveforms of the hydrogen wave function. The program has 4 option's. First, plotting the radial function, second, plotting the radial probability, third, 2d wave function,last, 3d wave function.

A Fast MAC based 3D Free surface fuid solver. Capable also of simulating viscoelastic fluids.Includes also wave equation solver for simulating shallow water phenomena.

NecJGui is an antennas design tool, interface for Numerical Electromagnetic Code. It allows easily making NEC input files, and viewing them in 3D. It also contains a version of the simulator, so it's complete IDE for full-wave EM simulation.
