HOTINT/MBS

- a flexible multibody system dynamics freeware code in C++

The HOTINT/MBS is a research software for flexible multibody system simulation. It has been mainly developed by J. Gerstmayr. Some contribution to the graphics and special elements have been made by Y. Vetyukov, M. Stangl and M. Dibold.
For more information about the different parts of the software click here.
Download HOTINT freeware multibody code V0.900
(zipped Windows-exe, 2.9MB)		 Download HOTINT documention Version0.900beta as PDF Online documention and help (included in HOTINT code)
User Interface Demo Video  Pendulum (2MB)
User Interface Demo Video Flexible  Slider-Crank (8.5MB)

It is planned to make further features of the software available in the windows version, however, this will take some time. If there are specific features which you are missing and would urgently need, just let me know!
Unfortunately, all the work for the freeware/windows interface must be done during private night work, because the university/government does not support this work.
