Detailed Description

Once the solver is created, you should not make any edits to the MocoProblem.

If you do, you must call resetProblem(const MocoProblem& problem).

Constructor & Destructor Documentation

◆ MocoSolver() [1/2]

OpenSim::MocoSolver::MocoSolver ( )

default

◆ MocoSolver() [2/2]

OpenSim::MocoSolver::MocoSolver ( const MocoProblem & problem )

explicit

This calls resetProblem() with the provided problem.

Member Function Documentation

◆ clone()

MocoSolver * OpenSim::MocoSolver::clone ( ) const

overridepure virtual

Create a new heap-allocated copy of the concrete object to which this Object refers.

It is up to the caller to delete the returned object when no longer needed. Every concrete object deriving from Object implements this pure virtual method automatically, via the declaration macro it invokes (e.g., OpenSim_DECLARE_CONCRETE_OBJECT()). Note that the concrete class overrides modify the return type to be a pointer to the concrete object; that still overrides the base class method because the return type is covariant with (that is, derives from) Object.

Implements OpenSim::Object.

Implemented in OpenSim::MocoCasADiSolver, OpenSim::MocoTropterSolver, and OpenSim::MocoDirectCollocationSolver.

◆ createGuessTimeStepping()

MocoTrajectory OpenSim::MocoSolver::createGuessTimeStepping ( ) const

(Experimental) Run a forward simulation (using the OpenSim Manager, which uses a SimTK::Integrator), using the default controls for actuators and the default states as the initial states, to create a guess that is dynamically consistent (constraint errors should be small).

The time range for the simulation is the upper bound on the initial time and the lower bound on the final time. The initial state values are the default state values unless:

initial bounds are an equality constraint: use the bound value
default value is not within the initial bounds: use midpoint of initial bounds.

The number of times in the trajectory is the number of successful integration steps.

Note: This function does not yet support problems with parameters.; This function assumes all actuators are in the model's ForceSet.

Exceptions

Exception If the lower bound on the final time is less than or equal to the upper bound on the initial time. This situation is okay in general; it's just that this function doesn't support it.

Precondition(s):: You must have called resetProblem().

◆ createProblemRepJar()

std::unique_ptr< ThreadsafeJar< const MocoProblemRep > > OpenSim::MocoSolver::createProblemRepJar ( int size ) const

protected

Create a library of MocoProblemReps for use in parallelized code.

◆ getClassName()

static const std::string & OpenSim::MocoSolver::getClassName ( )

inlinestatic

This returns "MocoSolver"

See getConcreteClassName() if you want the class name of the underlying concrete object instead.

◆ getConcreteClassName()

const std::string & OpenSim::MocoSolver::getConcreteClassName ( ) const

overridepure virtual

Returns the class name of the concrete Object-derived class of the actual object referenced by this Object, as a string.

This is the string that is used as the tag for this concrete object in an XML file. Every concrete class derived from Object automatically overrides this method via the declaration macro it uses. See getClassName() to get the class name of the referencing (possibly abstract) class rather than the concrete object.

See also: getClassName()

Implements OpenSim::Object.

Implemented in OpenSim::MocoCasADiSolver, OpenSim::MocoTropterSolver, and OpenSim::MocoDirectCollocationSolver.

◆ getProblemRep()

const MocoProblemRep & OpenSim::MocoSolver::getProblemRep ( ) const

inlineprotected

◆ resetProblem()

void OpenSim::MocoSolver::resetProblem ( const MocoProblem & problem ) const

Call this to prepare the solver for use on the provided problem.

The solver creates and stores a MocoProblemRep using the provided problem.

◆ safeDownCast()

static MocoSolver * OpenSim::MocoSolver::safeDownCast ( OpenSim::Object * obj )

inlinestatic

For use in MATLAB and Python to access the concrete class.

Example: cObj = MocoSolver.safeDownCast(obj). This is equivalent to dynamic_cast<MocoSolver*>(obj) in C++.

◆ setSolutionStats()

static void OpenSim::MocoSolver::setSolutionStats	(	MocoSolution &	,
		bool	success,
		double	objective,
		const std::string &	status,
		int	numIterations,
		double	duration,
		std::vector< std::pair< std::string, double > >	objectiveBreakdown = `{}`
	)

staticprotected

This is a service for derived classes, because MocoSolution::setStatus(), MocoSolution::setSuccess(), etc.

are private but this class is a friend of MocoSolution.
