Minsky brings system dynamics and monetary modelling to economics. Models are defined using flowcharts on a drawing canvas (as are Matlab's Simulink, Vensim, Stella, etc). Minsky's unique feature is the "Godley Table", which uses double entry bookkeeping to generate stock-flow consistent models of financial flows. Minsky is good for demonstrating mathematics too, with the most "math-like" interface in system dynamics. Sign up to Minsky's Patreon page (for as little as $1 a month) at...

RANSFOIL is a console program to calculate airflow field around an isolated airfoil in low-speed, subsonic, transonic or supersonic regime by numerically solving the Reynolds averaged Navier-Stokes (RANS) equations using mature computational fluid dynamics (CFD) method. As postprocess results, the aerodynamic parameters of the airfoil, e.g., lift coefficient and drag coefficient, can be integrated from the airflow distribution near wall boundary. In addition, the coupling between airflow and...

ViennaSHE is a modern semiconductor device simulator for 1D, 2D and 3D device simulation. It relies on deterministic solutions of the Boltzmann Transport Equation using Spherical Harmonics Expansions.

The Open Optimal Control Library is a software framework in Matlab/Octave for modeling optimal control problem. It uses automatic differentiation and fast non-linear programming solvers. It implements direct methods. In the backend it uses CasADi and ipopt.

This library contains several of user material subroutines for implicit quasi-static (UMAT) and explicit dynamic (VUMAT) versions of the Abaqus solver. The project web site: http://abumpack.sf.net. The Abaqus is a proprietary finite element (FE) code ( http://www.3ds.com/products-services/simulia/products/abaqus/). Users can write subroutines for use with the Abaqus. Linear elastic, isotropic hardening plasticity, Gurson-Tvergaard-Needleman (GTN), Rousselier constitutive models are provided. ...

QSapecNG is a Qt-based symbolic analysis program for linear analog circuits. In fact, it consists of two indipendently parts: the SapecNG framework engine, and the application gui QSapecNG.

JMCAD is an program for the modeling and simulation of complex dynamic systems. This includes the ability to construct and simulate block diagrams. The visual block diagram interface offers a simple method for constructing, modifying and maintaining complex system models. The simulation engine provides fast and accurate solutions for linear, nonlinear, continuous time, discrete time, time varying and hybrid system designs.

This is the program and data to accompany both the thesis and paper under the name A MINE ALTERNATIVE TO D-OPTIMAL DESIGNS FOR THE LINEAR MODEL This contains the program and summary of the data used for the paper.

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.

VOpR - A Virtual Optical Rail VOpR allows to create and evaluate simple optical systems, in which the basic optical elements are arranged along the optical axis. The current supported optical elements are: spaces,spherical lenses, circular apertures and flat blocks of some optical medium. The program has three main components: 1. The database editor. Currently the database can store data about: -optical materials, -spherical lenses, -projection properties of light sensors and eyes, -special wavelengths of light and -optical systems as lists of basic optical elements. 2. The editor of linear optical systems. Some properties of the optical system are calculated in real time. 3. ...

ViennaFEM is a library-centric implementation of the finite element method in C++. It features a symbolic math kernel, which manipulates the strong or weak form of the problem and automatically derives the discrete form. ViennaFEM is built on top of the following libraries: ViennaMath provides the symbolic math kernel, ViennaGrid (with ViennaData) allows for a generic grid handling and quantity storage, while ViennaCL provides the linear solvers and GPU acceleration.

Pydusa is a package for parallel programming using Python. It contains a module for doing MPI programming in Python. We have added parallel solver packages such as Parallel SuperLU for solving sparse linear systems.

OpenEERS (Open Earthquake Engineering Response Simulator) is a Matlab program for computing and animating the linear elastic response of discrete multiple degree of freedom structural systems using Newmark's Method.
