Hi,

My guess is that there is a problem with the configuration of the OpenSim API in Matlab. Did you run the configureOpenSim.m as adiminstrator and do you have the opensim bin folder in your path ?

Hi Dimitar,

Thanks for you response.
Indeed, the problems originated in this line: Thanks,

Hi, I want to acces the position of a specific body inside the computeControls function of my controller class. I tried this as follows void COM_MuscleController::computeControls(const SimTK::State& s, SimTK::Vector& controls) const { OpenSim::Body body_sel = getModel().getBodySet().get("calcn_l"); ...

Hi Mojtaba, You could try Friedl her method for solving the muscle redundancy problem ( https://simtk.org/projects/optcntrlmuscle/ ). This direct collocation method does not invert the mass matrix. But be carefull, we have only tried it for the lower limb muscles during walking and running. regards,...

Dear Opensim users, I would like to use the position, velocity and acceleration of my model as input for a controller. Inside my controller class, I’m able to calculate the position and velocity of the whole body COM. (s = state) --- SimTK::Vec3 com_position =getModel().calcMassCenterPosition(s); --...

Hello,

I think you should first make an ArrayStr from the path, since SetForceSetFile requires an ArrayStr as input.
Maybe this works:

cmcTool.setForceSetFiles(ArrayStr([residualMotorsFilePath residualMotors]))

But I'm also a first time user of Opensim (this could be wrong).

Maarten,

Dear Opensim Users, I’ve a question with regards to defining a pointactuator through the matlab API. After scaling of the model, I want to adjust the location of the residual actuators in the actuator file . As you can see in the functions below, I search for the location of the COM of the pelvis in...
