5 February 2019 -- PyChrono

PYCHRONO
The new Python wrapper for Chrono is called PyChrono The PyChrono library replaces the old Chrono::PyEngine library. The most relevant feature is that PyChrono is available as a precompiled Anaconda package. This means that an automated nightly build system will continuosly build the most recent C++ library, it will generate the Python wrapper, then it will upload it onto the pychrono channell of Anaconda cloud. This happens for Windows and Linux platforms, for Python 3.5 or 3.6 or 3.7, etc. Automatically. The installation on your system is managed by Anaconda, that also takes care of all dependencies. After the installation, you can import different modules of PyChrono, such as pychrono.postprocess, pychrono.irrlicht, pychrono.fea, pychrono.mkl, etc.

9 September 2018 -- Isymtec cloud-based GUI

The ISYMTEC company https://www.isymtec.ai has released a first demo of its web GUI for Multi-body System Simulation in Cloud. They use Chrono as a simulation library, run in the cloud. Thanks to the cloud technology, no installation is needed – sign up and build a MBS model in your browser, download and save it. It work from anywhere – all you need is internet connection and a browser. In future you’ll be able to perform scalable calculations in the cloud. They kindly released their code for the serialization and parsing of the models at: https://github.com/IsymtecAi/isymtecai-chrono-parser.

17 July 2017 -- Chrono 3.0.0 released

Future development of Chrono::Engine has been discussed.

25 November 2013 -- New web site layout

The www.projectchrono.org website has been redesigned with new logos and a new structure for documentation and indexes.

The build system of Chrono::Engine has been modified: after compilation, the binaries (.exe, .dll, etc.) won't be placed in the ChronoEngine/bin/ directory, as before, but they will be generated in the output directory that you choose in CMake. This makes the support of new platforms easier. A new nightly build system is under development, so that precompiled binaries and libraries will be periodically generated for free download for everyone.

30 August 2007 -- Ebmedded Bullet collision detection engine

The collision engine of Chrono::Engine has been updated to the most recent version the [Bullet](http://www.bulletphysics.com) collision detection library. The Bullet library features advanced and robust algorithms for fast collision detection. NOTE 1: in Chrono::Engine, only the collision detection features of the Bullet library are used, since we use the Chrono::Egine custom methods for all the rest (physics, etc.). NOTE 2: since the Bullet library is embedded in the Chrono::Engine library, you do not need to download and install Bullet -- it is completely wrapped inside Chrono::Engine, and you do not need to know anything about it (just keep on using the same C++ functions that you used with the previous releases).

13 July 2007 -- New Chrono::Engine release v.0.1.9.

The new release v.0.1.9 can be downloaded from this site. It fixes some compatibility issues with the latest Irrlicht 1.3.1 libraries. The previous Chrono::Engine SDK was compatible only with Irrlicht 1.3. From this release, we support Irrlicht v1.3.1 or superior. Note that the Irrlicht library is needed only for compiling the demos with 3D realtime views. NOTE!!! this 0.1.9 release replaces the 0.1.8 of two days ago, because we updated the installer and the makefiles, so it can be installed also in paths containing spaces, ex: "C:\\Program files\\chronoengine".

25 June 2007 -- ECCOMAS conference on Multibody

The Chrono::Engine middleware has been presented at the [Multibody Dynamics 2007](http://www.multibody2007.org) ECCOMAS international conference, in Milano (25-28 June 2007). More than 200 researchers meet at the conference and presented recent theorethical developements and applications of multibody dynamics. Among these, also Chrono::Engine simulations, software architecture and mathematical foundations were presented.

15 March 2007 -- Improved collision engine

The collision engine has been updated, and now it is able to simulate more than 32'000 objects. The solver has been improved as well. See an example with 36'000 pebbles in a reactor, in the updated [gallery](gallery.php).

10 January 2007 -- New friction model

The HyperOCTANT solver has been modified in order to accomodate a better friction model. Benchmarks showed a superior precision and a proper convergence for the solution. No modification is required in user code.

30 November -- New tutorials on-line

We updated the page with the [tutorials](tutorials.php), now you can browse also the tutorials about the Chrono::Engine integration in the Irrlicht 3D realtime visualization library.
</div>

28 August -- Run-time executables

We are developing run-time executables showing the Chrono::Engine in action. These interactive demos will be available soon on this site, as soon as the first beta release of the SDK will be published. In the SDK you will find the corresponding C++ source code to generate each example, and the corresponding tutorial.

27 July -- Integration tools for IRRLICHT

We choose [IRRLICHT](http://irrlicht.sourceforge.net/features.html) as our 'official' realtime 3D engine. The free and powerful Irrlicht library offers a clean and easy-to-use C++ API, it is platform independent and uses either OpenGL or DirectX, so we adopted it as the default way of showing Chrono::Engine simulations in realtime 3D views. Note that other 3D engines can be used as well, such as OGRE or DirectX, but the source code for examples provided in Chrono::Engine will use Irrlicht. To allow rapid developement of application based on Chrono::Engine + Irrlicht, we provide also some utility C++ classes.

7 June 2006 -- Porting on Visual C++ 2005

The CHRONO::ENGINE has been successfully passsed the compatibility test for the Microsoft Visual C++ 2005. The Microsoft Visual C++ 2005 compiler, in the 'Express' edition, can be downloaded for free. (The Express edition replaces the older 'Visual Toolkit 2003' free compiler: it has less limitations and also includes the IDE). Note: to use the Visual C++ 2005, you must also install the Microsoft Platform SDK (also free) because some libraries are needed by Chrono::Engine.

4 May 2006 -- Chrono::Engine official logo

The official logo for Chrono::Engine has been designed (it is a 'Chrono::Engine' string surrounded by two stylized rings). Also, an official 'demo picture' has been created with the Realsoft3D rendering software: it represents the inner mechanisms of a clock (somewhat inspired to the complex movement of a real Vacheron-Constantin clock). This raytraced picture will be used for flyers, web site, etc.

1 April 2006 -- Web site created

The web site for the CHRONO::ENGINE project has been created. Please report wrong links and suggesions about the site content.

15 March 2006 -- Porting on GNU C++ (MingW)

The CHRONO::ENGINE has been successfully passsed the compatibility test for the GNU C++ compiler (MingW distribution). Heretofore, the multibody engine now includes also a dynamic library for people which want to link it using in projects based on the MingW compiler.
