There is a test case that demonstrates adding a PrescribedController to a Model in testControllers.cpp (see testPrescribedControllerOnBlock()): https://github.com/opensim-org/opensim- ... s.cpp#L212

You may be able to build a model of pain, depending on the source of the pain. The following resources describe some of the capabilities of the muscle models currently available in OpenSim: - "Muscle Model Theory and Publications" page on Confluence: http://simtk-confluence.stanford.edu:8080/display...

The Doxygen documentation for Manager ( https://simtk.org/api_docs/opensim/api_docs/classOpenSim_1_1Manager.html ) might have helped: it lists three constructors, one of which "takes a model only and builds integrator internally". do I know which integrator is taken now? The documentation doesn't in...

Thanks for clarifying. Some of the SimTK classes are not wrapped and access/modification via Matlab is limited. In this case, you can do the following: import org.opensim.modeling.* model = Model('myModel.osim'); manager = Manager(model); %constructs an integrator internally manager.setIntegratorAcc...

Have you tried using Model.LoadOpenSimLibrary()? See viewtopicPhpbb.php?f=91&t=6387.

You may find some useful information in the following recent publication:

if I have OpenSim source code, add the CoupledBushingForce into Actuator folder, use CMake to create the solution and then build the OpenSim. Do you think this way will work? You would also need to register the object using Object::registerType() (see OpenSim/Simulation/RegisterTypes_osimSimulation...

The C1083 error ("Cannot open include file: 'OpenSim/Simulation/osimSimulationDLL.h': No such file or directory") points to one problem. Have you added the directory containing the plugin to the "librarypath" in Matlab? See http://simtk-confluence.stanford.edu:8080/display/OpenSim/Using+Plugins , po...

The name of the class is RungeKuttaMersonIntegrator (the mathematician's name was Kutta, with a "u"). Here's the doxygen documentation: https://simtk.org/api_docs/simbody/3.5/ ... rator.html).

1. getMultibodySystem() returns a MultibodySystem, not an integrator. There is no setAccuracy() method on MultibodySystem (see https://simtk.org/api_docs/simbody/3.5/classSimTK_1_1MultibodySystem.html ). 2. setAccuracy() is a method, not a field; the accuracy would be set by calling something like t...
