hydromodpy.spatial.mesh.gmsh_grid.catchment_mesh_bundle#

Export self-contained catchment mesh bundles for external reuse.

The bundle format is intentionally plain:

  • one copied planar .msh file,

  • CSV tables for nodes, cells, edges, and geology fractions,

  • one JSON metadata file describing conventions and optional payloads.

That keeps the export easy to inspect manually and easy to reuse from small external scripts that do not want to import the full HydroModPy stack.

The geology / hydraulic-properties / river projections live in dedicated sibling modules; this file orchestrates their results and writes the final artifacts.

Functions

export_catchment_mesh_bundle(*, mesh_path, ...)

Export one catchment mesh bundle and return a compact summary.

resolve_default_catchment_mesh_bundle_dir(...)

Return the default sibling directory used for one exported bundle.
