Physics libraries such as ODE provide excellent real-time simulation, embedding them in a 3D application to create a virtual reality is far from trivial. It is often prohibitively difficult to create a simulated reality that incorporates complex dynamic objects that interact with each other and the environment under physics’ constraints.
One of the major obstacles is mapping between meshes and objects supported by the physics engine.—This is what EZPhysics aims to solve.
EZPhysics API is licensed under the GNU Lesser Public License (LGPL).
The system is composed of two parts:
- Editor & Simulator—Lets you interactively embed objects supported by the physics engine into 3D meshes, attach joints and constraints to the physics objects, save the “physically rigged” scenes into files, and run simulations.
- API—Lets you embed the “physically rigged” meshes into your application. This involves using classes and methods for reading the editor files and manipulating the physical aspects of the objects, such as applying torques and forces to joints.

Manual:
CAELinux is a computer aided engineering Linux distribution.They say you just insert the CAELinux LiveDVD in a computer and turn it into a professionnal CAE workstation.
It is based on the open-source CAE softwares Salomé, Code_Aster, Code_Saturne and OpenFOAM , you can load your CAD geometry in Salomé and start partitionning and meshing your problem in just 5 minutes.
Then you can simulate incredibly complex physics with the open-source FE & CFD solvers Code_Aster, Code-Saturne, OpenFOAM & Elmer: non-linear thermo-mechanics, coupled fluid-structure dynamics, seismic / non-linear explicit dynamics, contacts, visco-plasticity, fluid dynamics, heat exchange, convection heat transfer and radiation, electro-magnetcis in other words nearly all physics problem can be addressed with the integrated solvers!! Then reload your results files in post-processing applications like Salomé, GMSH, Visit, or Paraview to visualize your data in 3D… And don’t forget all these features are based on free softwares.

Modelica is an object-oriented, declarative, multi-domain modeling language for component-oriented modeling of complex systems, e.g., systems containing mechanical, electrical, electronic, hydraulic, thermal, control, electric power or process-oriented subcomponents. The free Modelica language[1] is developed by the non-profit Modelica Association[2]. The Modelica Association also develops the free Modelica Standard Library[3] that contains about 780 generic model components and 550 functions in various domains, as of version 3.0[1].
Scicos is a graphical dynamical system modeler and simulator developed in the Metalau project at INRIA, Paris-Rocquencourt center. With Scicos, user can create block diagrams to model and simulate the dynamics of hybrid dynamical systems and compile models into executable code. Scicos is used for signal processing, systems control, queuing systems, and to study physical and biological systems. New extensions allow generation of component based modeling of electrical and hydraulic circuits using the Modelica language.
With Scicos you can:
- Graphically model, compile, and simulate dynamical systems
- Combine continuous and discrete-time behaviors in the same model
- Select model elements from Palettes of standard blocks
- Program new blocks in C, Fortran, or Scilab Language
- Run simulations in batch mode from Scilab environment
- Generate C code from Scicos model using a Code Generator
- Run simulations in real time with and real devices using Scicos-HIL
- Generate hard real-time control executables with Scicos-RTAI and Scicos-FLEX
