Simulation with external force and SO
Posted: Mon Sep 25, 2017 8:45 am
Hi everyone,
I'd like to perform a simulation with arm26.osim model, in particular I'd like to see how adding a force to the model the joint reactions and the muscle activations change, but I have some doubts about the process that I have to follow.
I've create a motion file and with it I've run Inverse Dynamic tool adding the force in the panel "External Loads" and selecting the body where the force acting. Is it correct?
After that I've run Static Optimization tool and in this way,if I understand correctly,I find the individual muscle forces at each instant in time and their activation.
To see Joint reaction I've run the Analysis tool -->joint reaction editing with the muscleforce.sto obtained with the SO.
I don't understand in the analysis tool the voice about "MuscleAnalysis" because I obtain a lot of files but to see how muscle activations change with or without a force I don't know which of this files is necessary, or maybe if is the file obtained as a results with the static Optimization thaat I've to see
Thank you
Maurice
