structure link history command

Syntax

structure link history <name s > keyword

Primary keywords:

displacement-x    displacement-y    displacement-z    displacement-rotational-x    displacement-rotational-y    displacement-rotational-z    force-x    force-y    force-z    moment-x    moment-y    moment-z

Samples relative displacement or force from a single degree-of-freedom in a structural element link.

If the optional name keyword is used, then the history can be supplied with a name to identify it later. If a name is not supplied, then one will be assigned automatically based on the internally created ID number of the history object.

The particular link must be identified either by coordinates (position v) or by ID (component-id i). In the case of coordinates, the closest available node to that location is found, and the link associated with that node is used.

displacement-x [linkhistoryblock]

relative displacement in the local \(x\) degree-of-freedom

displacement-y [linkhistoryblock]

relative displacement in the local \(y\) degree-of-freedom

displacement-z [linkhistoryblock]

relative displacement in the local \(z\) degree-of-freedom

displacement-rotational-x [linkhistoryblock]

relative angular displacement in the local \(x\) degree-of-freedom

displacement-rotational-y [linkhistoryblock]

relative angular displacement in the local \(y\) degree-of-freedom

displacement-rotational-z [linkhistoryblock]

relative angular displacement in the local \(z\) degree-of-freedom

force-x [linkhistoryblock]

force in the local \(x\) degree-of-freedom

force-y [linkhistoryblock]

force in the local \(y\) degree-of-freedom

force-z [linkhistoryblock]

force in the local \(z\) degree-of-freedom

moment-x [linkhistoryblock]

moment in the local \(x\) degree-of-freedom

moment-y [linkhistoryblock]

moment in the local \(y\) degree-of-freedom

moment-z [linkhistoryblock]

moment in the local \(z\) degree-of-freedom

Keyword Block

The following keywords are available to specify which link will be used to take a history. displacement-rotational-x, displacement-rotational-y, displacement-rotational-z, displacement-x, displacement-y, displacement-z, force-x, force-y, force-z, moment-x, moment-y and moment-z.

component-id i

the particular link is identified by the component ID number. If this keyword is used position should not be used.

position v

the particular link is identified by (v) coordinates (the nearest node is taken). If this keyword is used, component-id should not be used.

side i

specifies which side of the node indicated in position should be used to find the link. By default, side 1 is used.
