100 km2, headwater Mesh, Outlet 27, Rivers only, 30% buffer

Note

This page and its static assets are auto-generated by python -m tools.doc_gallery. The Sphinx build only reads committed PNG and JSON artifacts.

This case is reserved for a catchment mesh where geology is removed from the internal constraint set, but the watershed boundary, support extent, and outside de-refinement stay aligned with the standard gallery workflow.

Original mesh figure copied from the imported meshing run and reused directly in the documentation.

Regional framing figure copied from the imported meshing run.

Case Setup

• Case family: 100 km2, headwater.

• Scale target: 100 km2.

• Outlet identifier: 27.

• Gallery variant: Rivers only, 30% buffer.

• Bundle-reported constraints mode: rivers_only.

What It Shows

• How the river network alone structures the internal conformal mesh when geology is not enforced.

• How the same buffered watershed support can be compared fairly against the geology-plus-rivers variant.

• How outside coarsening still protects the basin focus while simplifying the external region.

Key Metrics

• Nodes: 2178

• Cells: 4312

• River edges: 717

• Geology interfaces: 343

Reproduce

Run the underlying example or validation case with:
