What's with that "TM" in Simbody™?
That trademark symbol is to let you know that we restrict how the name "Simbody" can be used. That's because we want to make sure that it is always clear to what that name refers. The license permits anyone to make any kind of derivative work, or to use all or part of Simbody code in any way they like, so it would become very confusing if all these works were called "Simbody". We hope you will say that your code makes use of Simbody (see below), but don't use the name except to refer to the Simbody project as it is distributed from the official hosting site at https://github.com/simbody/simbody. This small restriction is in the best interests of all Simbody users, including you, since it avoids confusion about what is, and what is not, the carefully managed Simbody community project. But ... if you want to make improvements to Simbody we would love to have your well-engineered, open source contributions to put into the main Simbody source tree, in which case they would be included under the Simbody name.
How to acknowledge us
Our license does not require that you acknowledge us, but we and our sponsors would be grateful if you did anyway! If our hard work has helped you with yours, please throw us a bone and mention on your "About" page and in your documentation that you are using Simbody from https://github.com/simbody/simbody. Where appropriate, please cite this paper:
Schmidt, J.P.; Delp, S.L.; Sherman, M.A.; Taylor, C.A.; Pande, V.S.; Altman, R.B. "The Simbios National Center: Systems Biology in Motion" Proceedings of the IEEE 96(8):1266-1280, 2008.
We would be particularly grateful if you mention that Simbody is primarily funded by NIH Roadmap grant U54 GM072970. We appreciate that support very much, and the NIH appreciates knowing that its funds are having an impact, particularly on medical research and human health.
