wall-structure create command

Syntax

wall-structure create ... <range>

Primary keywords:

angle    group    name    skip-errors    starting-shell

Wrap FLAC3D structural elements with PFC walls. PFC walls are, by definition, edge-connected sets of triangular facets without any non-manifold conditions (i.e., facets penetrating one another, multiple facets sharing one edge, etc). The provided range is applied to FLAC3D shell-based structural elements, filtering the structural elements that are considered for wrapping.

angle f

Only consider elements with normal within f degrees of the initial shell element, as specified with the starting-shell keyword.

group s <keyword>

Add the group name s to shell elements that are coupled via PFC wall facets. Use of the group logic is described in Groups.

remove

Remove s from the shell elements. If a slot is not specified, the group name is removed from all slots it is found in.

slot s

Assign the group to the slot named s. The default slot name is Default.

name s

Set the wall name to s. If a coupled wall with this name exists, new facets, corresponding to shell elements, are added to this wall. If the wall does not exist, a new coupled wall is created. If no name is specified, the wall name is set to wallstructureXX where XX is the next available wall ID.

skip-errors

Skip any errors when stitching together the wall facets from shell elements.

starting-shell i

Select the first shell element to be added. i is the component ID of the shell element. This shell element should be within the model domain (see the model domain command).
