Hello All,

I realize that the OpenSim 4.0 API works with a new Simbody version 3.6.

Is there any access to the Simbody 3.6 documentation online?

Thank you.

Hello All,

I am currently testing OpeSim 4.0 API which works with Simbody 3.6.

I'd like to know if there's online documentation available for Simbody 3.6.

Thank you.

Hello Ajay, Thank you for your comment. I am designing a controller which considers the forces acting on the model in order to compute the controls in the next time step. With the limitation (inability to call realizeDynamics in computeControls), how would you suggest I obtain and use contact forces...

Hello, Maybe something to try is to avoid any copying to intermediate variables, so your ForceValue() function looks something like this: CODE: SELECT ALL _model->getMultibodySystem().realize(s, SimTK::Stage::Dynamics); Array<double> F = _model->getForceSet().get(index).getRecordValues(s) This was d...

Hello, I don't know whether you're using 3.3 or 4.0, but it looks like your PDController2 class derives from OpenSim's Controller class and I don't see setKp() or setKv() methods in the Controller class in either OpenSim version (e.g., http://myosin.sourceforge.net/1987/classOpenSim_1_1Controller.ht...

Hello, Thanks for your response. I am still experiencing the challenge. I realized the state to Dynamic (and also Acceleration) stage and the result is still same. It fails at the "F = contact.getRecordValues(s)" line and the error is "Access violation reading location 0x0000000000001030" I added th...

Hello Tom,

Thanks for getting back. Please I am not clear on what you mean. Can you please expatiate on what you would like me to try out?

Hello Carmichael,

I ran the INSTALL build and then re-ran the test, but the test is still failing.

Not sure what's causing this.

Hello Carmichael, Thanks for the suggestion. I tried that out with my model, but I am getting an access violation error (Access violation reading location 0x0000000000001030). Here's how I set up my code: ForceSet forces = _model->getForceSet(); OpenSim::Force& contact = forces.get(3); // the elasti...

Hello Chris, Thanks for the pointer. With Git installed on my PC, I was able to build the OpenSim dependencies and generate the project files successfully. I also completed the ALL_BUILD process, but the RUN_TESTS_PARALLEL failed. The MATLAB tests are failing. Here's the error: The following tests F...
