Statistics Filters (Crystallographic)

Description

Determines Initiators, Hard Features, Soft Features and Hard-Soft Pairs in microtextured voxelized structures. Initiators are alpha globs defined as the user defined angle range between the c-axis ([0001]) and the user defined stress axis. Hard Features are microtextured regions (MTRs) defined as the user defined angle range between {10-17} plane normal and the user defined stress axis. Soft Features are MTRs defined as the user defined angle range between the c-axis ([0001]) and the user defined stress axis. Note that the Initiators and Soft Features calculations is the same as the Find Basal Loading Factor filter calculation. Hard-Soft Pairs are HardFeatures - Soft Features pairs with a neighboring Initiator that is not flagged here. Note the Stress Axis does not have not be a unit vector. Note that Lattice Parameter A and Lattice Parameter C is defaulted for alpha Ti. The Subsurface Feature Distance To Consider defines a subvolume in which only Features whose centroid lies within the subvolume are considered for Initiators, Hard Features, Soft Features and Hard-Soft Pairs criteria. All other Features are ignored.

Type Default Name Description Comment Filters Known to Create Data
Feature FeatureEulerAngles Three (3) angles (floats) defining the orientation of each Feature in Bunge convention (Z-X-Z). Find Average Orientations (Statistics), Match Crystallography (SyntheticBuilding)
Feature FeaturePhases Phase Id (int) specifying the phase of the Feature. Find Feature Phases (Generic), Read Feature Info File (IO), Pack Primary Phases (SyntheticBuilding), Insert Precipitate Phases (SyntheticBuilding), Establish Matrix Phase (SyntheticBuilding)
Feature NeighborLists List of the contiguous neighboring Features for a given Feature. Find Feature Neighbors (Statistics), Find Feature Neighborhoods (Statistics)
Feature Centroids X, Y, Z coordinates (floats) of the Feature center of mass. This filter will calculate Feature centroids if not previously calculated. Find Feature Centroids (Generic)
Ensemble CrystalStructures Enumeration (int) specifying the crystal structure of each Ensemble/phase (Hexagonal=0, Cubic=1, Orthorhombic=2). Values should be present from 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.
