<r>I think I sorted out my problem. I guess I was just wrong in my implementation.<br/> <br/> <br/> ***This is what I was doing:<br/> <br/> PrescribedForce *force1 = new PrescribedForce(body);<br/> force1->setForceFunctions(&OpenSim::Constant(1.0), &OpenSim::Constant(1.0), &OpenSim::Cons...

<t>Hi Ayman,<br/> <br/> My program throws the exception as it performs the osimModel.print() function, so no new model is made so I can't load the model in the GUI to see if the new force is added.<br/> <br/> Does this give a clue to why the exception is being thrown? If I comment out the osimModel....

<t>Hello, I am trying to write a c++ program to use the OpenSim API to perform a static simulation using the Stanford upperlimb model. In a nutshell what I'm trying to do is:<br/> <br/> 1 - Position the arm into a specific pose<br/> 2 - Apply an external load to the model's hand<br/> 3 - Calculate t...

Thanks for the help Ayman. You were right, I made the change and my program now works great.

Thanks again!

<r>Hi, I'm fairly new to c++ and even newer to opensim, so please be gentle <E>:)</E><br/> <br/> I want to perform some simulations using the Stanford upper limb model in which I repeat the analysis with variations to the model (different inertia properties, scale, etc). I was thinking rather than e...
