Summary:
Feature to export muscle lines of force

Detailed description
A tool to export the directions of (selected) muscle forces during the analyzed task would be extremely useful for all the users that use OpenSim to set up the boundary conditions for finite element simulations. This feature could be just connected to the kinematics assigned to the model and distinct from muscle force estimation, which would be performed with the already existing tools. A plugin with similar functionality was sketched at the last OpenSim workshop.

Date: 2012-11-13 19:05 Sender: Ayman Habib From a duplicate feature request by Tim Dorn: Have the ability to output muscle lines of action (muscle force) vector for user specified muscles (in a user specified coordinate frame) during a motion. This "line of action" vector can be quite difficult to calculate offline if the muscle has a complex path. In addition, the line of action will change constantly with the motion, so obtaining this information manually would have to be done on a frame by frame basis. It therefore would fit nicely inside the MuscleAnalysis analysis. This would be beneficial to researchers that are performing muscle force calculations on an OpenSim model and then using these results as input to more detailed FE models (therefore, they need not only the muscle force, but also its line of action vector)
