Identify Dislocation Segments

Group (Subgroup)

Unsupported (FeatureIdentification)

Description

This Filter groups neighboring Features that have c-axes aligned within a user defined tolerance. The algorithm for grouping the Features is analogous to the algorithm for segmenting the Features - only the average orientation of the Features are used instead of the orientations of the individual Cells and the criterion for grouping only considers the alignment of the c-axes. The user can specify a tolerance for how closely aligned the c-axes must be for neighbor Features to be grouped.

NOTE: This filter is intended for use with Hexagonal materials. While the c-axis is actually just referring to the <001> direction and thus will operate on any symmetry, the utility of grouping by <001> alignment is likely only important/useful in materials with anisotropy in that direction (like materials with Hexagonal symmetry).
