Particle-subset area conservation for ZDEM — Delaunay / matplotlib triangulation, color# filtering, paper figure scripts, sample-first CI.
Batch analysis of ZDEM .dat frames: select particles by color group, build a triangular mesh, track area statistics under deformation. Automates what used to be ad-hoc MATLAB leftovers.
Area_Conservation.py (getopt CLI):
- Reads ZDEM dumps through
zdemio/ plots viazdemplot - Builds triangulation (
matplotlib.tri.Triangulation/scipy.spatial.Delaunay) - Filters by color# / group conventions used in lab packs
- Writes mesh figures + area trend stats
- Uses
Aggbackend for headless figure export - Auto-detects Chinese fonts for paper labels when available
Supporting figure scripts: fig1_*.py … fig8_areatrend.py for algorithm flow, benchmarks, complex models, filtering, area trends.
