Find Feature Reference Misorientations

Group (Subgroup)

Statistics (Crystallographic)

Description

This Filter calculates the misorientation angle between each Cell within a Feature and a reference orientation for that Feature. The user can choose the reference orientation to be used for the Features from a drop-down menu. The options for the reference orientation are the average orientation of the Feature or the orientation of the Cell that is furthest from the boundary of the Feature.

Note: the average orientation of the Feature is a typical choice, but if the Feature has undergone plastic deformation and the amount of lattice rotation developed is of interest, then it may be more reasonable to use the orientation near the center of the Feature as it may not have rotated and thus serve as a better reference orientation.

Parameters

Name Type Description
Reference Orientation Enumeration Specifies the reference orientation to use when comparing to each Cell

Required Objects

Kind Default Name Type Component Dimensions Description
Cell Attribute Array FeatureIds int32_t (1) Specifies to which Feature each Cell belongs
Cell Attribute Array Phases int32_t (1) Specifies to which Ensemble each Cell belongs
Cell Attribute Array Quats float (4) Specifies the orientation of the Cell in quaternion representation
Feature Attribute Array AvgQuats float (4) Specifies the average orientation of the Feature in quaternion representation (, w). Only required if the reference orientation is selected to be the average of the Feature
Cell Attribute Array GBEuclideanDistances float (1) Distance the Cells are from the boundary of the Feature they belong to. Only required if the reference orientation is selected to be the orientation at the Feature centroid
Ensemble Attribute Array CrystalStructures uint32_t (1) Enumeration representing the crystal structure for each Ensemble

Created Objects
