I cannot include OpenSim.h in my mex file

Hi everyone, I am trying to create a mex file so that I can call opensim functions from MatLab. My test.cpp file is as below: #include "mex.h" #include <OpenSim/OpenSim.h> using namespace OpenSim; using namespace SimTK; void mexFunction( int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[] ) {...

How can I realize the system to a new stage? - MatLab API

Hi Everyone,
I was wondering if it is possible to realize the system to a new stage, using MatLab API?
In C++ i use this:

Code: Select all

model.getMultibodySystem().realize(state, Stage::Acceleration);
Is there any similar method available, if I want to use matlab API?
Thanks

how can i set initial states in forward dynamics-MatLab API

Hi All I want to set the initial states (joint angles and velocities) to specific values and use forward dynamics to integrate the equations of motion forward in time. I am using MatLab API. here is my script: system = osimModel.initSystem(); modelCoordinateSet = osimModel.updCoordinateSet(); modelC...

Re: Using import org.opensim.modeling.*

Hi All
I just understood how to solve the problem.
If i launch MatLab from start menu and the change MatLab working directory to the folder which contains the m files, everything will work. But if I double click on the m file to launch MatLab, it returns the above mentioned error.

How can I terminate FD integration before the final time?

Hi everyone
I am an API user and I was wondering if there is a way to terminate forward dynamic integration before reaching to the preset "Final Time".
For example is there any way to terminate the integration if a parameter (e.g hip angle) reaches to a limit value?
Thanks

Re: Why does HuntCrossleyForce apply torques?

Hi Sherman,
I am using a couple of contact spheres on the sole of foot to model the foot-ground contact and obviously the contact spheres are not at foot origin(foot centre of mass).
So this is only reporting the rXf vector an these torques are not applied to the foot? am I right?
Thanks,
Sina
