Ordinary Differential Equation (ODE) solver for Tcl. Handles both stiff and non-stiff sets of equations; does time-evolved initial value problems and root finding. Based on the popular Lawrence Livermore solver LSODE.

FSEM is a set of freeFEM++ scripts and C++ code to solve the drift-diffusion (DD) semiconductor device equations by the finite element method (FEM). It was initially developed for the nonlinear study of semiconductors under high optical injection.

PredatorPreySimulation is a graphical Java application for simulating a predator prey ecosystem using the Volterra-Lotka equations.

A framework for generation of real-time numerical simulations of dynamical systems from differential and difference equations.

A repository of Direct Numerical Simulation codes (Full solutions of the Navier Stokes Equations in fluid dynamics) in various geometries using a mix of high-order finite-difference and spectral methods.

Octave interface to the finite elements library Libmesh. Under the scientific interpreted language Octave, Octmesh allows using the Libmesh characteristics for the numerical simulation of partial differential equations on serial and parallel platforms.

OpenFlower is a free and open source CFD code (for Linux and Windows) mainly intended to solve the turbulent incompressible Navier-Stokes equations with a LES approach. It can deal with arbitrary complex 3D geometries with its finite volume approach.

SimED is a user-friendly Differential Equation simulation software. It can integrate numerically ODEs (Ordinary Differential Equations) using several methods, plot time and phase-space diagrams for variables, and interactively choose initial conditions.

Freeode is a compiler for the SIML programming language. It is a specialized language to solve differential equations. The compiler creates a python program that uses Numpy and Scipy to do the numerical computations.

...A dedicated function exports orbits as .xyzv Celestia files. b) a perturbations toolbox that allows to numerically assess the effect of arbitrary perturbations by integrating Gauss equations. Atmospheric drag, Sun pressure and J2 gravity potential are implemented. c) a rendez-vous and docking module that uses Clohessy-Wiltshire equations to optimize rendez-vous and docking maneuvers, assess the effect of the target's gravity field and analyze the effect of position and velocity uncertanties. d) a Simulink ADCS simulator with a focus on control law design.

Integrates the Vlasov-Maxwell equations in three dimensions for multiple particle species and arbitrary physical geometries.

HyperSim is a Navier-Stokes and Maxwell equations solver. It use the same method-"finite volume" to solve fluid and electromagnetic field. This technique could sharing the same mesh for simulation and make the multi-discipline optimization design possi
