Detailed Description

A class for computing the powers delivered to contact elements induced by the individual actuators of a model.

This analysis depends on a valid contact force decomposition and the velocities of the contact points, both expressed in the global frame.

This class is derived from suIndContactPowers, which holds model states and the contact force decomposition.

Constructor & Destructor Documentation

suIndContactPowers::suIndContactPowers (  rdStorage *  aContactVelocities, rdModel *  aModel, rdStorage *  aStates, rdStorage *  aControls, char *  aBaseName, char *  aDir = NULL, char *  aExtension = NULL )

Construct an induced contact powers object based on a set of contact point velocities, model states, and a contact force decomposition. Parameters: aContactVelocities  Velocities of the contact point expressed in the global frame. See class suContact. aModel  Model on which the simulation was run. aStates  Set of model states. aBaseName  Base name for the force decompositon files. If NULL, accelerations are computed based on a NULL decompostion. aDir  Directory in which the results reside. aExtension  File extension of the force decomposition files. See also: suContact, suIndAcc

Member Function Documentation

rdStorage * suIndContactPowers::getContactVelocities (   )

Get the contact velocities. Returns: Contact velocities.

int suIndContactPowers::printResults (  char *  aBaseName, char *  aDir = NULL, double  aDT = -1.0, char *  aExtension = ".sto" )  [virtual]

Print results. The file names are constructed as aDir + "/" + aBaseName + "_" + ComponentName + aExtension Parameters: aDir  Directory in which the results reside. aBaseName  Base file name. aExtension  File extension. Returns: 0 on success, -1 on error. Reimplemented from suIndAcc.
