Actuator interface for a muscle computes the tension in the muscle and applied by the tendon to bones (i.e.

not the fiber force)

void OpenSim::Schutte1993Muscle_Deprecated::connectToModel ( Model model)
overrideprotectedvirtual

Perform any necessary initializations required to connect the component into the Model, and check for error conditions.

connectToModel() is invoked on all components to complete construction of a Model, prior to creating a Simbody System to represent it computationally. It may also be invoked at times just for its error-checking side effects.

If you override this method, be sure to invoke the base class method first, using code like this:

void MyComponent::connectToModel(Model& model) {
Super::connectToModel(model); // invoke parent class method
// ... your code goes here
}

Note that this method is expected to check for modeling errors and should throw an OpenSim::Exception if there is something wrong. For example, if your model component references another object by name, you should verify that it exists in the supplied Model, which is not guaranteed since components may be independently instantiated or constructed from XML files.

Parameters
[in,out]modelThe Model currently being constructed to which this ModelComponent should be connected.

Reimplemented from OpenSim::ModelComponent.
