General information

OpenSim is an open source software system for biomechanical modeling, simulation and analysis. We will introduce OpenSim and demonstrate how musculoskeletal modeling can be used to address sport-related research questions. We will provide several hands-on examples to get familar with the OpenSim. 

All participants will have access to computers equipped with OpenSim and Notepad++. OpenSim model files and setup files are written in xml mark down format. Notepad++ is a free text editor that makes it easier to view and edit these xml files.  During the workshop we will use Notepad++ to examine OpenSim files.
