Find Field Average C-Axes

Group (Subgroup)

Statistics Filters (Crystallographic)

Description

This Filter determines the average c-axis location of each Field by the following algorithm:

  1. Gather all Cells that belong to the Field
  2. Determine the location of the c-axis in the sample reference frame for the rotated quaternions for all Cells.
  3. average the locations and store as the average for the Field.

Note: This filter will only work properly for Hexagonal materials. The filter does not apply any symmetry operators because there is only one c-axis (<001>) in Hexagonal materials and thus all symmetry operators will leave the c-axis in the same position in the sample reference frame. However, in Cubic materials, for example, the {100} family of directions are all equivalent and the <001> direction will change location in the sample reference frame when symmetry operators are applied.

Parameters

None

Required DataContainers

Voxel

Required Arrays

Type Default Name Description Comment Filters Known to Create Data
Cell GrainIds Ids (ints) that specify to which Field each Cell belongs. Values should be present from segmentation of experimental data or synthetic generation and cannot be determined by this filter. Not having these values will result in the filter to fail/not execute. Segment Fields (Misorientation, C-Axis Misorientation, Scalar) (Reconstruction), Read Dx File (IO), Read Ph File (IO), Pack Primary Phases (SyntheticBuilding), Insert Precipitate Phases (SyntheticBuilding), Establish Matrix Phase (SyntheticBuilding)
Cell Quats Five (5) values (floats) that specify the orientation of the Cell in quaternion representation Filter will calculate the quaternion for each Cell if it is not already calculated. Find Cell Quaternions (Generic)
