Adds a history of a rigid block value. A history is a table of floating point values assigned by sampling a model attribute periodically during a simulation. Review the common c history commands for details regarding the manipulation of histories.

The history can be assigned a name for later reference with the optional name keyword, if not the history will be given a default name based on its internally assigned id number.

Following one of the keywords given below, either 1) an additional id keyword followed by an integer id, or 2) an additional lkwd:\(position\) keyword followed by a position vector v must be given to define the specific rigid block.

displacement

Magnitude of the accumulated rigid block displacement vector as a result of cycling.

displacement-x

The x-component of accumulated displacement as a result of cycling.

displacement-y

The y-component of accumulated displacement as a result of cycling.

displacement-z (3D ONLY)

The z-component of accumulated displacement as a result of cycling.

euler-x (3D ONLY)

The x-euler angle (in degrees) of the current rigid block orientation. The orientation is updated only when orientation tracking has been enabled (see the model orientation-tracking command). See the euler keyword of the rblock attribute command.

euler-y (3D ONLY)

The y-euler angle (in degrees) of the current rigid block orientation. The orientation is updated only when orientation tracking has been enabled (see the model orientation-tracking command). See the euler keyword of the rblock attribute command.

euler-z (3D ONLY)

The z-euler angle (in degrees) of the current rigid block orientation. The orientation is updated only when orientation tracking has been enabled (see the model orientation-tracking command). See the euler keyword of the rblock attribute command.

force-contact

The magnitude of the force resulting from contacts.

force-contact-x

The x-component of the contact force.

force-contact-y

The y-component of the contact force.

force-contact-z (3D ONLY)

The z-component of the contact force.

force-unbalanced

The magnitude of the unbalanced force (sum of the applied, contact and gravitational forces).

force-unbalanced-x

The x-component of the unbalanced force.

force-unbalanced-y

The y-component of the unbalanced force.

force-unbalanced-z (3D ONLY)

The z-component of the unbalanced force.
