The Development System for Auditory Modelling (DSAM) is a computational library designed specifically for producing simulations of the auditory system. It brings together many established auditory models within a flexible programming platform.

...The pressure field is approximated via piecewise linears in both cases. Both stationary and time-dependent regimes supported. Elementary graphing tools are provided. GMRES and CG iterative algorithms are used for solving linear systems. Software "Triangle" is used for mesh generation.

Isogeometric analysis (IGA) is a fundamental step forward in computational mechanics that offers the possibility of integrating methods for analysis into Computer Aided Design (CAD) tools and vice versa. The benefits of such an approach are evident, since the time taken from design to analysis is greatly reduced leading to large savings in cost and time for industry. The tight coupling of CAD and analysis within IGA requires knowledge from both fields and it is one of the goals of the...

XonGrid is a free Excel library of functions to perform 1D, 2D, 3D, 4D and arbitrary dimension (ND) interpolations from scattered data.

ASCEND is a modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provid

This utility, lingen, implements evolution of native machine code via linear genetic programming. The assembly level code uses a subset of assembly language which manipulates and performs calculations using the floating point unit (FPU) of the CPU.

...EPRI decided to release the simulation kernel of LPDW under an open-source license (GPL v3), so it may be incorporated into IEEE Flash and other projects. OpenETran can presently simulate multi-conductor power lines, insulators, surge arresters, non-linear grounds, and lightning strokes. It efficiently calculates energy and charge duty on surge arresters, and iterates to find the critical lightning current causing flashover on one or more phases. It is also suitable for use in substation insulation coordination. Capacitor switching, TRV, and other applicaitons may be added. EPRI originally had permission to use code from the Numerical Recipes book in LPDW. ...

A graphical MatLab framework for estimating the parameters of, modeling and simulating static and dynamic linear and polynomial systems in the errors-in-variables context with the intent of comparing various estimation strategies.

uspice (Micro-SPICE) is a very small simulator for electrical circuits. The primary platform are low-power devices, such as graphing calculators.

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.

Symofros is a robotics modeling software originally created by the Canadian Space Agency. Symofros basic functions include modeling Kinematics, Non-linear dynamics, Linear dynamics, Dynamics for constrained systems, and Systems with flexible links.
