◆ AddExternalForce() [1/2]

void AddExternalForce ( const LinearVectorType _force,
const FrameID _forceInCoordinatesOf = FrameID::World(),
const LinearVectorType _position = LinearVectorType::Zero() 
)

Add a force on the link applied at a specified position. This force is applied for one simulation step only. This is a convenient form of AddExternalForce where the force and position are free vectors and an additional parameter is used to specify the coordinates in which the force is expressed.

Parameters
[in]_forceThe desired force
[in]_forceInCoordinatesOfThe coordinates in which the force is expressed
[in]_positionThe point of application of the force expressed in the link-fixed frame.

Note that in this version of AddExternalForce the position is expressed in the link-fixed frame while the coordinate frame for the force is a parameter that can be set. If you want to specify the reference frame for the position quantity, please use the AddExternalForce function that takes Relative quantities.

◆ AddExternalForce() [2/2]

void AddExternalForce ( const RelativeForceType _force,
const RelativePositionType _position 
)

Add a force on the link applied at a specified position. This force is applied for one simulation step only.

Parameters
[in]_forceThe desired force as a Relative Force (a quantity that contains information about the coordinates in which it is expressed)
[in]_positionThe point of application of the force. This parameter is a Relative Position (a quantity that contains information about the frame in which it is expressed).

◆ AddExternalTorque() [1/2]

void AddExternalTorque ( const AngularVectorType _torque,
const FrameID _inCoordinatesOf = FrameID::World() 
)

Add an external torque on the link. The torque is applied for one simulation step only.

Parameters
[in]_torqueThe desired torque
[in]_inCoordinatesOfThe coordinates in which the torque is expressed

◆ AddExternalTorque() [2/2]

void AddExternalTorque ( const RelativeTorqueType _torque)

Add an external torque on the link. The torque is applied for one simulation step only.

Parameters
[in]_torqueThe desired torque as a Relative Torque (a quantity that contains information about the coordinates in which it is expressed)
