Open Source C Simulation Software for Linux

A parametric, feature-based, sketch-driven 3D CAD application, built around a geometrical constraint solving engine. Project is in early development stage. The FreeSG library (http://freesg.org/) is required.

SaVi - simulate Starlink, Iridium, Globalstar, O3b, GPS, Galileo and other satellite constellations, modify them, or design your own. Requires Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.

Calculation of radiation view factors by adaptive integration. A cross-platform port of the public-domain code by George Walton.

Create phyiscal simulations easily through IPSA which combines the OpenInventor 3D API with the Open Dynamics Engine (ODE). Scenes are read from .iv files and simulated in the supplied viewer applications. Find it at: http://ipsa.sourceforge.net

Labcoat for SuperWikia Alpha fabrication manages new or revised fabrication processes. Its 'Cleanroom' applets allow codesmiths to access the lab environment, used to create semiconductors, substrate prototypes, chipset instruction blocks and other Labcoat projects. Our extensions in future releases will include UML support for C#/C++ conforming projects, import/export architecture schematics and refactoring sub-projects.

The OpenCMISS-Zinc Library (opencmiss.org/zinc), or Zinc, is a software library for building interactive graphical modelling and visualisation applications. Models are represented in Zinc as mathematical fields defined over domains, including finite elements with support for high-order basis functions, complex parameter mappings and time variation, and image-based fields. Further fields can be defined by mathematical expressions and algorithms on existing fields, including image processing filters. Zinc model data structures are dynamic, supporting interactive applications which programmatically create, destroy and modify parts of models.

Ruby-Newton is a Ruby wrapper for the NewtonGameDynamics physics engine ( http://newtondynamics.com/ ) It brings object-oriented real-time animated physics simulations to Ruby-enabled applications (e.g. 3D modeling tool with interactive scripting support

SCS is a smart car simulator. It build a virtual envirement according to the rules of the National University "The Freescale Cup" Smart Car Racing. SCS simulate the track and the car. SCS is based on ODE and OpenGL.

SpiceX is a simple schematic capture program for graphical interaction with Spice-based electronic simulation cores, i.e., placing components, wires and test points. SpiceX creates NETLISTs and runs simulations directly from the GUI.

Over 75 C++ function for working with vectors, matrix and quaternions. Inside the package there is no cycles, if's, classes or structures. Ideal for designing 3D engines. Headlines of functions are intuitive. For each headline there is a one line comment in Russian. Matrix are presented in OpenGL form 0 4 8 12 1 5 9 13 2 6 10 14 3 7 11 15 Now we are working on adding 50+ more functions for processing the planes, splines, bezier curves and interpolation methods.

Collection of utilities based on two basics classes: Matematica and VarData. Matematica) performs math operations on vectors and matrices for smoothing, interpolation, convolution, image processing... VarData) manipulate a structure of points connected by links. Addraw) openGL engine. ElPoly) analyze mechanical properties of polymer and membrane like structures. Addyn) perform molecular dynamics and Monte Carlo simulations and has a solver for 4th oder PDE. Avvis) perform all the operation of Matematica on different sets of data visualized on a Qt graphical interface. DrImage) image manipulation on the Matematica filters. The program is intended to use as less as possible external libs (optional: openGL, gsl, fftw, cgal, png, tiff, boost, MPI, Qt...).

pyFormex is a program for generating, transforming and manipulating large geometrical models of 3D structures by sequences of mathematical operations.

pymesh will be a Python interface for Triangle (2D) and Tetgen (3D) mesh generators.
