Detailed Description

JointInternalPowerProbe is a ModelComponent Probe for computing an operation on internal joint power or sum of joint powers in the model during a simulation.

E.g. Joint internal work is the integral of joint internal power with respect to time, so by using the JointInternalPowerProbe with the 'integrate' operation, Joint internal work may be computed.

Implements OpenSim::Probe.

virtual OpenSim::Array<std::string> OpenSim::JointInternalPowerProbe::getProbeOutputLabels ( ) const
overridevirtual

Returns the column labels of the probe values for reporting.

Currently uses the Probe name as the column label, so be sure to name your probe appropiately!

Implements OpenSim::Probe.

const bool OpenSim::JointInternalPowerProbe::getSumPowersTogether ( ) const

Returns whether to report sum of all joint powers together or report the joint powers individually.
