Hello everyone, I am little confused with the arm26. When I set and lock the r_shoulder_elev at 90, set 130 to the r_elbow_flex and then Simulate, the forearm goes in extension and doesnt "fall" in elbow flexion. After investigation, I've discovered that it is due to the passive force of the Triceps...

Hi, thanks again Dimitar. I tried this code (equivalent of what you have posted) and it works ! import org.opensim.modeling.* model = Model('arm26.osim'); state = model.initSystem(); ForeArm = model.getBodySet().get( 'r_ulna_radius_hand') ; massCenter = Vec3(0.0,0.0,0.0); position = Vec3(0.0,0.0,0.0...

Hi, Thank you for your reply Dimitar ! I'm a beginner using Opensim's method on matlab. But this code seems to compute moment arm of a muscle, in my case I need to obtain the moment arm of body ('r_ulna_radius_hand'). If there is not method to compute this moment arm, I think that I can have it by o...

Hello everyone, Currently working on Arm26 model, considering only 2 muscles (BRA and TRIlat) on Matlab. I need to obtain the moment arm of the forearm body (elbow joint to the center of mass) of the model as a Matlab double numeric type. I tried to use MomentArmSolver(model).solve(state, Coordinate...

Dear colleagues,

Currently in internship dealing with OpenSim and Matlab, I would like to know if the CMCtool class and its methods (API) are usable on Matlab ?

Thank you,
