Detailed Description

A class to perform an Induced Accelerations analysis using a constraint- method of replacing external (contact) forces in order to determine the contributions of actuators to external reaction forces and thus model accelerations including that of the center-of-mass.

The analysis reports the contributions of all forces to user identified accelerations of coordinates, bodies and/or center-of-mass.

Induced Accelerations can apply any OpenSim::Constraint that implements setContactPointForInducedAccelerations() to replace external forces, which are precisely the same external forces (ExternalLoads file) applied during the forward dynamics simulation being analyzed.

The ConstraintSet supplied must have the same number constraints as external forces AND apply to the same bodies with respect to ground.

Member Typedef Documentation

◆ Self

This typedef might be useful within the member functions of this class.

This is generated by the OpenSim_DECLARE_*_OBJECT macros.

◆ Super

Use this typedef to refer to the superclass of this class.

Avoid using the explicit type name of the superclass; this would introduce bugs if the superclass is changed.

◆ clone()

InducedAccelerations* OpenSim::InducedAccelerations::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.

◆ getConcreteClassName()

const std::string& OpenSim::InducedAccelerations::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.
