structure node list command

Syntax

structure node list keyword <range>

Primary keywords:

acceleration    apply    connectivity    damping    displacement    fix-local    fixity    group    link    mass    position    ratio-target    stiffness    system-local    system-surface    unbalanced-force    velocity

List properties and responses of structural element nodes in the range.

acceleration <keyword>

translational and rotational acceleration. The following keywords, if present, specify the coordinate system in which these values are expressed.

global

values are expressed in the global system

local

values are expressed in the node-local system. This is the default if no keyword is specified.

apply <keyword>

apply conditions on the node. One of the following keywords can be supplied to specify which apply condition is listed.

force

applied force and system in which it is specified (global or node-local). This is the default if no keyword is specified.

moment

applied moment and system in which it is specified (global or node-local)

connectivity

component-id numbers of all structural elements that are connected to this node

damping

damping type (local, combined, Rayleigh or Maxwell) and associated properties

displacement <keyword>

translational and rotational displacement. The following keywords, if present, specify the coordinate system in which these values are expressed.

global

values are expressed in the global system

local

values are expressed in the node-local system. This is the default if no keyword is specified.

fix-local

fixity state of node-local coordinate system (if free, then the system orientation will be set by the structural element that uses the node; if fixed, then the system orientation will remain fixed).

fixity

velocity fixity conditions for each degree of freedom (free, fixed or slaved to velocity of target object)

group <slot s >

group assignment(s). If slot is specified, then list the group assignment, if any, in slot s.

component-id numbers of any links that are attached to the node

mass

translational and rotational mass expressed in the node-local system

position <keyword>

position. There are two different position values; the following keywords (if present) allow you to select which position is listed. By default, the reference position is listed.

current

current position of the node, which is updated from the starting (or reference) position even in small-strain mode

reference

reference position of the node, which is updated only in large-strain mode. In small-strain mode, this is the initial location of the node and does not change. The reference position corresponds to the nodal position at the time that the stiffness matrices of all finite elements that use the node were formed.

ratio-target

target local force ratio that is considered to be converged for mechanical calculations (see the ratio-target keyword in the structure node initialize command)

stiffness

translational and rotational stiffness expressed in the node-local system

system-local

orientation of the node-local coordinate system

system-surface (3D ONLY)

orientation of the surface coordinate system

unbalanced-force

unbalanced force and moment (equal to sum of all forces and moments acting on the node). The following keywords, if present, specify the coordinate system in which these values are expressed.

global

values are expressed in the global system

local

values are expressed in the node-local system. This is the default if no keyword is specified.

velocity <keyword>

translational and rotational velocity. The following keywords, if present, specify the coordinate system in which these values are expressed.

global

values are expressed in the global system

local

values are expressed in the node-local system. This is the default if no keyword is specified.
