Multi-material sections

Section polygons may overlap and each polygon has a numeric priority. The higher-priority polygon governs an overlap (concrete defaults to 0, steel to 1). Analysis resolves the polygons into disjoint FEM material regions, automatically tightens the mesh for thin shapes, and reports resolved area by material. Saved projects use schema version 3. Concrete materials require a positive compressiveStrengthACI value in psi; projects created before this field was introduced are not migrated automatically.

Deploy to the RETUG Django site

Run the complete production build, Django-template conversion, and changed-file copy with:

npm run deploy:retug

The deploy script copies only files whose SHA-256 hash changed. It publishes the Webpack bundle, Tailwind CSS, disc.png, and the generated conc_gui.html template to C:\Users\16142\Desktop\re-tug_site.

To preview what would change without copying anything:

powershell -NoProfile -ExecutionPolicy Bypass -File scripts/deploy-retug.ps1 -DryRun

The Django template is generated from index.html by scripts/generate-django-template.mjs. Edit index.html, not deployment/conc_gui.html; the generator preserves the production Django static paths, Google Analytics setup, cookie consent, and disclaimer link, and fails if development-only asset paths remain.
