hello, i am still struggling to get the force :cry: using body.PrescribedForce.getForceAtTime(1.0) says that returns zero if the three functions are not defined. according to the below code the functions are defined. (i didnt put all the lines to avoid complexity) body = foot1.getBodySet().get('foot...

hello, i have a simple matlab code which loads the model and makes a free falling. clear all; import org.opensim.modeling.* foot1 = Model('C:\Users\shayan\Desktop\model-20170712T165116Z-001/foot1.osim'); s = foot1.initSystem(); manager = Manager(foot1); x0 = foot1.updCoordinateSet().get('y'); x0.set...

Last month, I asked about obtaining whole-body center of mass kinematics. This is in the context of running a forward simulation to evaluate the objective function for an optimization problem. I have one case where I only need to know the CM kinematics at the initial time and the final time. Ajay’s...

hi, i really appreciate your response. here is my code. it builds fine but when i open the .exe file it says program stopped working. #include <OpenSim/OpenSim.h> #include <cmath> using namespace OpenSim; using namespace SimTK; using namespace std; //=================================================...

hi, i am trying to create an externally applied force as: for 0-0.3 time of simulation the force is constant, from 0.3-1 the force follows a sine function and from 1-2 the force is a linear function. i wonder how can i use prescribed force to combine these three different force functions? or do i ha...

Hello
I have a model in Adams which is simulated based on torque motion, I would like to switch to opensim and simulate it based on muscle excitation
How can I do that?
Thanks
