Grain Boundary Operations

Grain Boundary Operations

UPXO provides dedicated modules for detecting, analysing, and operating on grain boundaries in 2D and 3D grain structures.

2D Grain Boundary Operations (gbops/mcgb2dops.py)

• Grain boundary pixel detection and labelling
• Boundary segment extraction
• Triple junction identification
• Boundary length and curvature metrics
• Misorientation angle computation (requires crystallographic orientation assignment)

---

3D Grain Boundary Operations (gbops/grainBoundOps3d.py)

• Grain boundary voxel/face detection
• Boundary area computation
• Boundary network construction

---

Boundary Zone Analysis (pxtalops/grain_boundary_zones.py)

Defines and analyses regions adjacent to grain boundaries — useful for studying near-boundary property gradients.

Coming Soon

• Full misorientation distribution functions
• Grain boundary character distribution (GBCD)
• Coincidence site lattice (CSL) boundary identification
