Adds a history of a wall 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, 2) an additional name keyword followed by a string s, or 3) an additional lkwd:\(position\) keyword followed by a position vector v must be given to define the specific wall.

displacement

Magnitude of the accumulated wall 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 wall orientation. The orientation is updated only when orientation tracking has been enabled (see the model orientation-tracking command). See the euler keyword of the wall attribute command.

euler-y (3D ONLY)

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

euler-z (3D ONLY)

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

moment-contact

{Value in 2D; Magnitude in 3D} of the sum of the contact moments.

moment-contact-x (3D ONLY)

The x-component of the contact moment.

moment-contact-y (3D ONLY)

The y-component of the contact moment.

moment-contact-z (3D ONLY)

The z-component of the contact moment.

position-x

The x-component of the location of wall centroid.

position-y

The y-component of the location of wall centroid.

position-z (3D ONLY)

The z-component of the location of wall centroid.

rotation (2D ONLY)

Current wall orientation. The orientation is updated only when orientation tracking has been enabled (see model orientation-tracking command).

spin

{Value in 2D; Magnitude in 3D} of the wall angular velocity in radians per second.

spin-x (3D ONLY)

The x-component of the wall angular velocity in radians per second.

spin-y (3D ONLY)

The y-component of the wall angular velocity in radians per second.

spin-z (3D ONLY)

The z-component of the wall angular velocity in radians per second.

velocity

Magnitude of the wall translational velocity vector.

velocity-x

The x-component of the wall velocity.

velocity-y

The y-component of the wall velocity.

velocity-z

The z-component of the wall velocity.
