Mesh Architecture#
How HydroModPy turns a watershed support into a solver-ready mesh: the catchment-conformal Gmsh pipeline, the structured-grid path used by MODFLOW-family solvers, and the cross-mesh pivot format consumed by plotting and I/O.
For higher-level runtime handoffs from process objects to solver adapters, see Process Architecture and Simulation Orchestration Class Diagram. For the scientific side of mesh choice, see Mesh And Spatial Support.

The dedicated mesh_catchment workflow, batch loop,
simulation embedding, output layout, and the conformal Gmsh
meshing core.
The FloPy StructuredGrid path used by MODFLOW-family
solvers, the build sequence, and the SGrid / FieldParam
discretization bridge.
The low-level Gmsh integration: constraint geometry, sizing callbacks, mesh-quality checks, and the boundary recovery that keeps geology and rivers honoured.
The cross-mesh pivot representation consumed by plotting, I/O, and downstream postprocessing. Bridges structured and irregular supports.
