Hi I switched to OpenSim 3.3 since I am using CEINMS toolbox. Unfortunately, when I run the configureOpenSim.m file in scripts folder of OpenSim 3.3 It throws an error (definitely cause its a much newer version of MATLAB) I have included that in the image. Is there any way I can configure them? Than...

When u download opensim, you will find resources folder in the setup folder. inside resources folder is a model folder which has many opensim models like 2392 and 2354. You can copy the setup files for IK and ID and modify them according to your study. Those models are lower limb models so you will ...

Hi everyone I was referred to this old post on OpenSim forum since I am facing the same issue as Andrew when i do RRA as well as body kinematics using Analyze tool. i checked all bodies have mass/ inertia. I am including my model as well. java.lang.RuntimeException: SimTK Exception thrown at SmallMa...

I think what u mean is your grf is not consistent with your IK.mot results that is the grf is not applied at the correct points of application. So i guess u need to check your COP calculations. I had similar issues and the COP calculation was wrong.

Thanks for responding Dr. Uchida. Has the model been designed for computing dynamics? If not, perhaps check for body segments that have zero mass and/or inertia, which could cause the error you are seeing. All the body segments have a mass /inertia so that's why i am not really sure what else could ...

Hello I am using this model by Hang Xu ( https://simtk.org/frs/?group_id=933 ) and added 4 more muscles in the legs. When I run the IK results associated with grf they are not consistent. I decided to use RRA to counter this, however, I am getting this error.. java.lang.RuntimeException: SimTK Excep...

Hi

I am having the same problem. Did you manage to solve it?

Thank you
