News & Announcements

NIH supports OpenSim for five more years

Nov 24, 2015

We are excited to announce that the OpenSim project has secured an additional five years of funding through the renewal of our NIH-funded National Center for Simulation in Rehabilitation Research (NCSRR). We are grateful to everyone who provided a letter of support for our renewal application, and we thank all members of the community for contributing to the growth and vibrancy of the project by participating in our forum, attending workshops, teaching with OpenSim, and publishing excellent research.

In the coming years, the NCSRR will continue to support and expand the OpenSim project by enhancing the OpenSim software platform and continuing our Visiting Scholars, Pilot Project, OpenSim Fellows, workshop, and online training programs.

OpenSim highlighted in the Nature Toolbox Blog

Oct 04, 2015

The Nature Toolbox blog highlighted OpenSim in a recent story,
Motion studies: See how they run
. The article included a broader discussion about the contributions of open-source modeling and simulation software for the study of human and animal locomotion. The article talks about the benefits, and drawbacks, of these large-scale software platforms as well as the communities they can create.

OpenSim gets high marks as a multibody system simulator

Aug 03, 2015

A recent study by Luca Tagliapietra and his University of Padua colleagues demonstrates that the OpenSim, which uses Simbody as its multibody dynamics engine, generates highly accurate simulations of mechanical systems. OpenSim was evaluated using the Multi-Body System (MBS) Benchmark, which consists of five systems ranging from a simple pendulum to an over-constrained system of five rods and six rotational joints (Bricard's mechanism).This work (extended abstract ) was presented at the 2015 European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS) Thematic Conference on Multibody Dynamics (see page 1572 of the Proceedings). You can learn more and download the code that implements the benchmarks in OpenSim here.

OpenSim community members earn awards for their research

Mar 13, 2015

Several students have recently been recognized for their work with OpenSim:

Oregon State University undergraduate Jade Montgomery won two awards from the College of Engineering for her research work conducted with Ravi Balasubramanian. Awards included the Undergraduate Researcher of the Year for 2013 and First Place in the poster competition at "Celebrating Undergraduate Excellence", 2013. Jade used OpenSim to study how effective implanted engineering mechanisms are in tendon-transfer surgery.

Florida high school students Christopher Fregly and Brandon Kim took first place in the Physics and Astronomy category at the Alachua Regional Science Fair. Working with NASA, Fregly and Kim used the OpenSim software to predict simple ways that astronauts could modify the standard squat exercise to be more effective at maintaining muscle mass on the International Space Station.
