OpenSim 3.3 Now Available with Enhanced Static Optimization, New Examples, and More Automated Workflow
by Announcements of the availability of OpenSim updates and resources 12 Jul '15

12 Jul '15

We are pleased to announce that OpenSim 3.3 is now available for download . The release includes new examples and scripts that make it even easier for you to get started and help you evaluate the quality of your simulations. Based on your feedback, we have also enhanced OpenSim to automate more of your workflow. Some of the improvements in the release include the following: * The Static Optimization tool now has better error handling and error messages. It is also compatible with models that have passive elements, so you can now solve muscle activation problems for a more diverse set of models, even those that include springs, ligaments, and bushing elements. * We created a new example demonstrating how to understand and improve the results of a Static Optimization analysis. * The Scale tool now automatically handles the scaling of ligaments, eliminating the need for the cumbersome manual process employed by users. * We created a new script to help generate a reserve and residual actuator file for use with RRA, CMC, or Static Optimization. You will be able to set up and run these tools much more quickly, while also avoiding common pitfalls that cause the tools to fail. * We have upgraded to Simbody 3.5 , which includes support for Contact mesh files in .obj or .stl format and several new features for advanced API users, including access to the CMA-ES global optimizer. * Several bug fixes based on reports from our users. * Compatibility with Visual Studio 2013 and Visual Studio 2015 Release Candidate If you're already using version 3.2, upgrading to 3.3 will require at most minimal changes to your models, scripts, and other files. Our website includes a full list of new features and upgrade notes . --- Joy P.

Request for Letters of Support for NCSRR/OpenSim
by opensim-announcement＠simtk.org 10 Feb '15

10 Feb '15

Dear OpenSim Community: We are submitting a proposal to continue support for the OpenSim project and are seeking letters of support from you, the OpenSim community, to strengthen our proposal. We have prepared a template to assist with writing these letters, and have attached it to this email. We hope to receive all letters of support by March 4. Our proposal is to renew the NIH National Center for Simulation in Rehabilitation Research <http://web.stanford.edu/group/opensim/index.html> (NCSRR) whose mission is to equip the rehabilitation research community with state-of-the-art simulation tools. Over the past five years, the NCSRR has developed and distributed OpenSim, provided training opportunities and seed grants, and helped form a network of biomechanical and clinical experts. With the renewal, we are seeking five years of additional funding for the NCSRR. The renewal will allow us to continue providing these resources to accelerate the integration of simulations into critical areas of rehabilitation, including stroke, spinal cord injury, cerebral palsy, osteoarthritis, prosthetics, orthotics, and sports medicine. With the renewal we will also adapt to meet the evolving needs of the community by focusing on (1) emerging research fields like wearable robotics, prosthetics, and predictive simulation, (2) expanding online resources including videos and e-books, (3) growing the OpenSim Fellows program, and (4) validation of models and simulations. It would be a great help to our proposal to have testimonial letters from you, stating how you currently use OpenSim and the other resources provided by the NCSRR. Letters that describe the specific ways that OpenSim and the NCSRR have benefitted your career or your research (e.g., assisting with publications and grants) will also strengthen our application. If your research has rehabilitation applications, please describe these as well. A diversity of letters from around the world will help our effort. Attached is a template you may find useful for writing the letter. It is also available to download here <http://web.stanford.edu/group/opensim/downloads/NCSRR_SupportLetterTemplate…> . We would be grateful if you could send a signed letter (preferably as a PDF file on your own letterhead) to opensim(a)stanford.edu by March 4. If you would like to provide a letter, but cannot meet this deadline, please let us know. Also, please let me know if you have any questions or ideas about the proposal. I'm happy to fill you in and we welcome your input. Thanks so much for your ongoing participation and support. Sincerely, Jen Hicks and the OpenSim Team -- *Jennifer Hicks, Ph.D.* Director of Data Science | Mobilize Center <http://mobilize.stanford.edu> Associate Director | NCSRR <http://www.stanford.edu/group/opensim/about/index.html> R&D Manager | OpenSim <http://opensim.stanford.edu/> Stanford University 650-498-4403 | jenhicks(a)stanford.edu
