Create a sun, spin some asteroids around it, and watch them collide and form planets. An N-Point Gravity Simulator is a realistic simulation in which all points attract each other: even the smallest asteroid has its own gravitational field that can affect even a large sun far away from it. Can be reused as a library for making games. If used as library, license is GNU LGPLv3, otherwise it's GNU GPLv3.

The Lightweight Integrating Multiphysics Environment for coupling codes (LIME) is a small software package for creating multiphysics simulation codes. 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. Also, modest high-level revisions or modifications to most stand-alone physics codes may be required to meet interface requirements. Detailed descriptions of these requirements together with example cases are provided in a users guide.

The Massively Parallel Quantum Chemistry program, MPQC, computes properties of atoms and molecules from first principles using the time independent Schrödinger equation.

This project concerns the design and implementation of an open-source flocking boids simulator, designed as a tool to analyze and characterize flock-like collective emerging behaviors. Each boid is conceived as an active agent and modelled by a point-mass approximation. Boid movements in a 3D space are guided by a set of elementary steering behaviors, each implemented as a force acting on the boid's point mass. Each boid is affected by interactions with both the environment and other boids. The set of considered behaviors are inspired by the well-known approach introduced in 1987 by C. W. Reynolds. The simulator delivers a 3D visual interface and provides as an output file all the instantaneous microscopic information related to each boid (positions and velocities over time), allowing in this way subsequent analysis, such as searching for synthetic and higher-level descriptions of collective behaviors, relying for instance on global network and meta-structural properties.

This project connects the ubiquitous circuit simulation software, SPICE, with the powerful tools of Mathematica. This allows the optimization of circuits based on arbitrarily complex criteria. For example, automatically tune component values to match a desired filter profile. Tweak a circuit to maximize its efficiency. Match a circuit's output to an arbitrary waveform. As long as you can quantify your goal as a fitness function, you can automate the search for the optimal component specs.

Unix-based preparation and analysis toolbox for Nanomaterials and Room Temperature Ionic Liquids in Bulk and Slab using bash scripts, Gromacs tools and Matlab functions. NaRIBaS provides a framework that decouples user input parameter and terminal based command lines. NaRIBaS does not replace a simulation software and specific analysis tools like Gromacs, but it allows iterative repetition of tasks while changing specific input parameter. The toolbox is to be understood as a scripting framework rather than a black-box software. Task specific input and preparation or analysis function, are easy expandable to meet the scientific characteristic of constant changing properties. Concepts for efficiently storing and analysing large files in conjunction with graphical visualization and numerical data processing are presented in a Manual. A documented script collection that allows reproducing all simulations and analysis results presented in the Doctoral thesis of the author.

PUPIL (Program for User Package Interface and Linking), is a software environment that allows developers to link quickly and efficiently together multiple pieces of software in a fully automated multi-scale simulation. More specifically, it supports QM/MM MD simulations where the user might choose among any of the different MD engines and QM engines, which are connected to PUPIL as external programs through a tiny specific interface. One of the main advantages here is that the user can use most of the functionalities that may have those external programs interfaced without the necessity to be reimplemented again on independent interfaces. In fact, this simulation interface concentrates all the common code involved in the coupling terms of the QM/MM approach.
