structure pile list
command
Syntax
- structure pile list keyword <range>
Primary keywords:
apply coupling-confinement coupling-normal coupling-shear coupling-yield element-type force-node group information length model plastic-state plastic-stress plastic-stress-bounds property system-local
Lists properties and responses of pile elements in the range. If no keyword is given, the default output of the command is that associated with the information keyword.
- apply
uniform applied distributed load acting on the element
- coupling-confinement
confining stress acting perpendicular to the element, values acting on the local y and z directions
- coupling-normal
information about the normal coupling springs connecting the pile to the target object (zones in FLAC3D and 3DEC, and particles in PFC3D): displacement, stress and normal direction
- coupling-shear
information about the shear coupling springs connecting the pile to the target object (zones in FLAC3D and 3DEC, and particles in PFC3D): displacement, stress and shear direction
- coupling-yield
yield state of the coupling springs in the normal and shear directions, and the current gap values
- element-type
finite element type
- force-node <keyword>
generalized nodal forces (force and moment) acting on the element. These are the generalized forces exerted by the nodes on the element.
- local
express the values in the element coordinate system (the default)
- global
express the values in the global coordinate system
- group <slot s >
group assignment(s). If slot is specified, then list the group assignment, if any, in slot s.
- information
general element information: nodal connectivity, centroid, surface area, volume, and hide/select status
- length
length of the element
- model
constitutive model
- plastic-state <integration-point ind >
Plasticity state indicators. Each beam element with a plastic material model has a number of integration points distributed throughout its volume, and each of them tracks its plasticity state. The plasticity states at all integration points are listed, unless integration-point is specified. The integration point locations are shown here and here. The plasticity states of the plastic constitutive models can be listed by the
structure pile cmodel list states
command.
- plastic-stress <integration-point ind >
Stress for elements with a plastic material model. The plasticity is induced by axial and bending deformations; twisting deformation induces an elastic response. Each beam element with a plastic material model has a number of integration points distributed throughout its volume, and each of them tracks its axial stress. The axial stress is the only non-zero stress component arising from axial and bending deformation. The axial stress (\(\sigma_{xx}\)) is expressed in the beam element coordinate system. The axial stress at all integration points is listed, unless integration-point is specified. The integration point locations are shown here and here.
- plastic-stress-bounds
minimum and maximum axial stress for elements with a plastic material model by checking over all integration points.
- property <integration-point ind > keyword <scaled bscaled >
The properties consist of constitutive model properties, beam-type properties, coupling-spring properties and rockbolt properties. The constitutive model properties are listed by specifying the constitutive property name; these names are not listed here. Elastic-plastic constitutive model properties are stored at each integration point. Such properties are the same at all integration points, except for the softening properties of the strain-softening/hardening Mohr Coulomb constitutive model. The value at a particular integration point is listed by specifying the integration-point keyword — the integration point locations are shown here and here.
Scaled properties are returned if the scaled keyword (FLAC2D ONLY) is set to true (the default is false). If the property cannot be scaled, an error is emitted.
