◆ calcIntegrandImpl()

void OpenSim::MocoOutputGoal::calcIntegrandImpl	(	const SimTK::State &	state,
		double &	integrand
	)		const

overrideprotectedvirtual

Precondition(s):: The state is realized to SimTK::Stage::Position. If you need access to the controls, you must realize to Velocity:
getModel().realizeVelocity(state);
The Lagrange multipliers for kinematic constraints are not available.

Reimplemented from OpenSim::MocoGoal.

◆ initializeOnModelImpl()

void OpenSim::MocoOutputGoal::initializeOnModelImpl ( const Model & ) const

overrideprotectedvirtual

Perform any caching before the problem is solved.

You must override this function and invoke setNumIntegralsAndOutputs().

Precondition(s):: The model is initialized (initSystem()) and getModel() is available. The passed-in model is equivalent to getModel(). Use this opportunity to check for errors in user input.

Implements OpenSim::MocoGoal.

◆ setDivideByDisplacement()

void OpenSim::MocoOutputGoal::setDivideByDisplacement ( bool tf )

inline

Set if the goal should be divided by the displacement of the system's center of mass over the phase.

◆ setOutputPath()

void OpenSim::MocoOutputGoal::setOutputPath ( std::string path )

inline

Set the absolute path to the output in the model to use as the integrand for this goal.

The format is "/path/to/component|output_name".
