Constructor & Destructor Documentation

suBodyPointIndAcc::suBodyPointIndAcc (  rdModel *  aModel, int  aBody, double  aPoint[3] )

Construct an instance for computing the induced accelerations of a point on a segment of a model during a simulation. Parameters: aModel  Model on which the analyses are to be performed. aBody  Body ID. aPoint Point value.

suBodyPointIndAcc::suBodyPointIndAcc (  rdModel *  aModel, int  aBody, double  aPoint[3], rdStorage *  aStates, rdStorage *  aControls, char *  aBaseName, char *  aDir = NULL, char *  aExtension = NULL )

Construct an instance for computing the induced accelerations of a point on a segment of a model from a set of force decomposition files. Note that the induced accelerations are not read in from file. The induced accelerations are recomputed based on the force decomposition. Parameters: aModel  Model on which the analyses were performed. aBody  Body ID. aPoint Point value. aStates  Set of model states. aBaseName  Base name for the force decompositon files. aDir  Directory in which the results reside. aExtension  File extension. Todo: verify induced accelerations are correct check that code is correct for generalized force case add initial velocity and ind pos due to init vel and pos to all

Member Function Documentation

int suBodyPointIndAcc::computePointAccelerations (   )

Compute the acceleration of a point on a body induced by the active force components of the model given a force decomposition and a set of states. Returns: 0 on success, -1 on error.

int suBodyPointIndAcc::getBody (   )

Get the body for which the induced accelerations are to be computed. Returns: Body ID

void suBodyPointIndAcc::getPoint (  double  rPoint[3]  )

Get the point for which the induced accelerations are to be computed. Parameters: rPoint  X-Y-Z Point

const char * suBodyPointIndAcc::getPointName (   )

Get the point name. Parameters: aName  Name for the point.

int suBodyPointIndAcc::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.

void suBodyPointIndAcc::setPointName (  const char *  aName  )

Set a name for the point. Parameters: aName  Name for the point.

void suBodyPointIndAcc::setStorageCapacityIncrements (  int  aIncrement  )  [virtual]

Set the capacity increments of all storage instances. Parameters: aIncrement  Increment by which storage capacities will be increased when storage capcities run out. Reimplemented from suIndAcc.
