Detailed Description

This defines the abstract ModelComponent class, which is used to specify components of a musculoskeletal model and the elements they add to the underlying computational SimTK::System (MultibodySystem).

A ModelComponent is an OpenSim::Component and therefore has the capabilities to add necessary system resources to the System and to manage access to those resources (

See also
Component)

Bodies, Joints, Coordinates, Constraints, Forces, Actuators, Controllers, and even Model itself, are ModelComponents. Each component is "connected" to a model and an underlying SimTK::Subsystem, which by default is the System's DefaultSubsystem.

The primary responsibility of a ModelComponent is to add its computational representation(s) of physical musculoskeletal structures to the underlying SimTK::System by implementing extendAddToSystem().

Additional methods provide support for adding modeling options, state and cache variables (

See also
Component).

Public methods enable access to component variables via their names.

Member Function Documentation

◆ clone()

ModelComponent * OpenSim::ModelComponent::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::Component.

Implemented in OpenSim::ActivationCoordinateActuator, OpenSim::BodyActuator, OpenSim::ClutchedPathSpring, OpenSim::ConstantMuscleActivation, OpenSim::CoordinateActuator, OpenSim::DeGrooteFregly2016Muscle, OpenSim::Delp1990Muscle_Deprecated, OpenSim::FirstOrderMuscleActivationDynamics, OpenSim::McKibbenActuator, OpenSim::Millard2012AccelerationMuscle, OpenSim::Millard2012EquilibriumMuscle, OpenSim::MuscleFirstOrderActivationDynamicModel, OpenSim::MuscleFixedWidthPennationModel, OpenSim::PointActuator, OpenSim::PointToPointActuator, OpenSim::RigidTendonMuscle, OpenSim::Schutte1993Muscle_Deprecated, OpenSim::SpringGeneralizedForce, OpenSim::Thelen2003Muscle, OpenSim::Thelen2003Muscle_Deprecated, OpenSim::TorqueActuator, OpenSim::ZerothOrderMuscleActivationDynamics, OpenSim::Set< ModelComponent, ModelComponent >, OpenSim::AccelerationMotion, OpenSim::DiscreteController, OpenSim::DiscreteForces, OpenSim::AckermannVanDenBogert2010Force, OpenSim::MeyerFregly2016Force, OpenSim::EspositoMiller2018Force, OpenSim::ControlSetController, OpenSim::PrescribedController, OpenSim::ActuatorForceProbe, OpenSim::ActuatorPowerProbe, OpenSim::Bhargava2004MuscleMetabolicsProbe, OpenSim::Bhargava2004SmoothedMuscleMetabolics, OpenSim::Blankevoort1991Ligament, OpenSim::BushingForce, OpenSim::ComponentSet, OpenSim::ConditionalPathPoint, OpenSim::ContactHalfSpace, OpenSim::ContactMesh, OpenSim::ContactSphere, OpenSim::CoordinateLimitForce, OpenSim::ElasticFoundationForce, OpenSim::ElasticFoundationForce, OpenSim::ElasticFoundationForce, OpenSim::ExpressionBasedBushingForce, OpenSim::ExpressionBasedCoordinateForce, OpenSim::ExpressionBasedPointToPointForce, OpenSim::ExternalForce, OpenSim::FunctionBasedBushingForce, OpenSim::GeometryPath, OpenSim::Ground, OpenSim::HuntCrossleyForce, OpenSim::HuntCrossleyForce, OpenSim::HuntCrossleyForce, OpenSim::JointInternalPowerProbe, OpenSim::Ligament, OpenSim::Marker, OpenSim::ModelComponentSet< T >, OpenSim::ModelComponentSet< ModelComponent >, OpenSim::MovingPathPoint, OpenSim::MuscleActiveFiberPowerProbe, OpenSim::PathActuator, OpenSim::PathPoint, OpenSim::PathSpring, OpenSim::PhysicalOffsetFrame, OpenSim::PointToPointSpring, OpenSim::PrescribedForce, OpenSim::SmoothSphereHalfSpaceForce, OpenSim::Station, OpenSim::SystemEnergyProbe, OpenSim::Umberger2010MuscleMetabolicsProbe, OpenSim::ExperimentalFrame, OpenSim::ExperimentalMarker, OpenSim::IMU, OpenSim::PositionMotion, OpenSim::BallJoint, OpenSim::Body, OpenSim::ConstantDistanceConstraint, OpenSim::Coordinate, OpenSim::CoordinateCouplerConstraint, OpenSim::CustomJoint, OpenSim::EllipsoidJoint, OpenSim::FreeJoint, OpenSim::GimbalJoint, OpenSim::PinJoint, OpenSim::PlanarJoint, OpenSim::PointConstraint, OpenSim::PointOnLineConstraint, OpenSim::RollingOnSurfaceConstraint, OpenSim::ScapulothoracicJoint, OpenSim::SliderJoint, OpenSim::UniversalJoint, OpenSim::WeldConstraint, OpenSim::WeldJoint, OpenSim::PathWrapPoint, OpenSim::WrapCylinder, OpenSim::WrapEllipsoid, OpenSim::WrapSphere, OpenSim::WrapTorus, OpenSim::CMC, OpenSim::CorrectionController, OpenSim::MuscleActivationDynamics, OpenSim::StationPlaneContactForce, OpenSim::Controller, OpenSim::AbstractPathPoint, OpenSim::ActivationFiberLengthMuscle, OpenSim::ActivationFiberLengthMuscle_Deprecated, OpenSim::Actuator, OpenSim::ScalarActuator, OpenSim::ContactGeometry, OpenSim::Force, OpenSim::Frame, OpenSim::Muscle, OpenSim::OffsetFrame< C >, OpenSim::OffsetFrame< PhysicalFrame >, OpenSim::PhysicalFrame, OpenSim::Point, OpenSim::Probe, OpenSim::TwoFrameLinker< Force, PhysicalFrame >, OpenSim::TwoFrameLinker< Constraint, PhysicalFrame >, OpenSim::Constraint, OpenSim::Joint, OpenSim::UnilateralConstraint, and OpenSim::WrapObject.

◆ connectToModel()

void OpenSim::ModelComponent::connectToModel ( Model model)

Connect this ModelComponent to its aggregate- a Model.

◆ extendConnectToModel()

virtual void OpenSim::ModelComponent::extendConnectToModel ( Model model)
inlineprotectedvirtual

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

extendConnectToModel() 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::extendConnectToModel(Model& model) {
Super::extendConnectToModel(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 in OpenSim::Delp1990Muscle_Deprecated, OpenSim::UnilateralConstraint, OpenSim::CMC, and OpenSim::CorrectionController.

◆ extendFinalizeFromProperties()

void OpenSim::ModelComponent::extendFinalizeFromProperties ( )
overrideprotected

◆ extendPostScale()

virtual void OpenSim::ModelComponent::extendPostScale ( const SimTK::State &  s,
const ScaleSet scaleSet 
)
inlineprotectedvirtual

Perform any computations that must occur after ModelComponent::scale() has been invoked on all ModelComponents in the Model.

This method is virtual and may be implemented by any subclass of ModelComponent, but all implementations must begin with a call to Super::extendPostScale() to execute the parent class methods before the child class method. The base class implementation in ModelComponent does nothing.

See also
postScale()

Reimplemented in OpenSim::ActivationFiberLengthMuscle_Deprecated.

◆ extendPreScale()

virtual void OpenSim::ModelComponent::extendPreScale ( const SimTK::State &  s,
const ScaleSet scaleSet 
)
inlineprotectedvirtual

Perform any computations that must occur before ModelComponent::scale() is invoked on all ModelComponents in the Model.

For example, a GeometryPath must calculate and store its path length in the original model before scaling so that an owning Muscle can use this information to update the properties of the muscle after scaling. This method is virtual and may be implemented by any subclass of ModelComponent, but all implementations must begin with a call to Super::extendPreScale() to execute the parent class methods before the child class method. The base class implementation in ModelComponent does nothing.

See also
preScale()

◆ extendScale()

virtual void OpenSim::ModelComponent::extendScale ( const SimTK::State &  s,
const ScaleSet scaleSet 
)
inlineprotectedvirtual

Scale the ModelComponent.

This method is virtual and may be implemented by any subclass of ModelComponent, but all implementations must begin with a call to Super::extendScale() to execute the parent class methods before the child class method. The base class implementation in ModelComponent does nothing.

See also
scale()

◆ getClassName()

static const std::string & OpenSim::ModelComponent::getClassName ( )
inlinestatic

This returns "ModelComponent"

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

◆ getConcreteClassName()

const std::string & OpenSim::ModelComponent::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.
