Detailed Description

A class implementing a RigidTendonMuscle actuator with no states.

The path information for a RigidTendonMuscle is contained in the base class, and the force-generating behavior should is defined in this class. The force (muscle tension) assumes rigid tendon so that fiber-length and velocity are kinematics dependent and the force-length force-velocity relationships are evaluated directly. The control of this model is its activation. Force production is instantaneous
with no excitation-to-activation dynamics and excitation=activation.

Reimplemented from OpenSim::Muscle.

◆ clone()

RigidTendonMuscle* OpenSim::RigidTendonMuscle::clone ( ) const

inlineoverridevirtual

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::Muscle.

◆ computeActuation()

double OpenSim::RigidTendonMuscle::computeActuation ( const SimTK::State & s ) const

overrideprotectedvirtual

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

not the fiber force)

Implements OpenSim::Muscle.

◆ computeInitialFiberEquilibrium()

void OpenSim::RigidTendonMuscle::computeInitialFiberEquilibrium ( SimTK::State & s ) const

inlineoverrideprotectedvirtual

compute initial fiber length (velocity) such that muscle fiber and tendon are in static equilibrium and update the state

Implements OpenSim::Muscle.

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

inlinestatic

This returns "RigidTendonMuscle".

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

◆ getConcreteClassName()

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

inlineoverridevirtual

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::Muscle.

◆ safeDownCast()

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

inlinestatic

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

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

Set the value of the active_force_length_curve property.
