Free software for simulation and modeling

The OpenSIMPLY package contains source code files, binary executables, and documentation files in various formats. All these components are free simulation software.

The source files containing the code of the OpenSIMPLY modules, examples, and tutorial may be used under the terms of the GNU General Public License GPLv3.

OpenSIMPLY documentation may be used under the terms of the GNU Free Documentation License FDLv1.3.

Third party software components, such as binary executables, including runtime libraries, and shared libraries, are subject to the terms of the end user license agreement for the applicable item.

There are four freedoms that every user should have:

• the freedom to use the software for any purpose,
• the freedom to change the software to suit your needs,
• the freedom to share the software with your friends and neighbors, and
• the freedom to share the changes you make.

Free software is computer software distributed under terms that allow the software users to run the software for any purpose as well as to study, change, and distribute the software and any adapted versions.

Free software is a matter of liberty, not price: users, individually or collectively, are free to do what they want with it, including the freedom to redistribute the software free of charge.

OpenSIMPLY is an open-source software. The right to study and modify the software implies that the source code of the software is available to its users.
