# structure geogrid list command

Syntax

structure geogrid list keyword <range>

Primary keywords:

List properties and response of each geogrid element in the range.

apply

uniform applied pressure acting on the element

coupling

Information about the shear coupling springs connecting the liner to the zones. The confining stress, displacement, yield state, and direction is given.

depth-factor

depth factor used during stress recovery

element-type

finite element type used

group <slot s >

list the group assignment(s) of this element. If slot is supplied, list the group assignment for this element, if any, in slot s.

information

Lists general element information, including id and component-id numbers, connected nodes, centroids, surface area, volume, and the hide and select status.

force-node keyword

List nodal forces. By default, components are displayed in terms of the element local coordinate systems. These are the forces exerted by the nodes on the element.

local

List forces in terms of the element local coordinate system (the default).

global

List forces in terms of the global coordinate system.

density

density, $$ρ$$

thickness

geogrid thickness

thermal-expansion

anisotropic membrane material-stiffness coefficients { $$c_{11}$$, $$c_{12}$$, $$c_{13}$$, $$c_{22}$$, $$c_{23}$$, $$c_{33}$$ }

anisotropic-bending

anisotropic bending material-stiffness coefficients { $$c_{11}$$, $$c_{12}$$, $$c_{13}$$, $$c_{22}$$, $$c_{23}$$, $$c_{33}$$ }

material-x

Vector used to determine the local X direction of the material coordinate system.

isotropic

isotropic material properties: $$E$$ and $$v$$, where $$E$$ is Young’s modulus $$[F/L^2$$$$]$$ and $$v$$ is Poisson’s ratio

orthotropic-membrane

orthotropic membrane material-stiffness coefficients { $$c_{11}$$, $$c_{12}$$, $$c_{22}$$, $$c_{33}$$ }

orthotropic-bending

orthotropic membrane material-stiffness coefficients { $$c_{11}$$, $$c_{12}$$, $$c_{22}$$, $$c_{33}$$ }

coupling-stiffness

coupling spring stiffness per unit area

slide

large-strain sliding flag

slide-tolerance

large-strain sliding tolerance

resultant <nodes>

all eight stress resultant quantities last calculated with the structure geogrid recover resultants command. If the nodes keyword is given the values of these quantities is supplied at each node of the element, in addition to the value at the element centroid.

stress <nodes>

the stress state calculated with the structure geogrid recover stress command. If the nodes keyword is given the values of these quantities is supplied at each node of the element, in addition to the value at the element centroid.

stress-principal <nodes>

principal stresses calculated with the structure geogrid recover stress command. If the nodes keyword is given the values of these quantities is supplied at each node of the element, in addition to the value at the element centroid.

system-local

element local coordinate system
