hydromodpy.spatial.mesh.io.vtu_io

VTU read/write for HydroMesh.

VTU (VTK Unstructured Grid XML) is the recommended portable disk format for both structured and unstructured HydroModPy meshes because it is:

• widely supported (ParaView, PyVista, meshio, QGIS via plugins),

• self-describing (vertices, connectivity, cell types, data arrays),

• format-agnostic regarding 2D vs 3D, structured vs unstructured.

This module intentionally remains thin and delegates the actual conversion to the meshio adapter layer.

Functions

read_vtu(path)	Read a VTU file into a HydroMesh.
write_vtu(path, hydro_mesh)	Write a HydroMesh to a VTU file and return the resolved path.
