hydromodpy.spatial.mesh.gmsh_grid.gmsh_reader

Read, normalize and write simple 2D Gmsh meshes.

This module is the low-level I/O layer for planar Gmsh support. It converts between external mesh representations (meshio objects or ASCII .msh content) and one small internal payload (GmshMeshData).

Its job is deliberately narrow: accept triangles or quads, normalize their connectivity, reject unsupported mixed cases, and keep file handling separate from the higher-level mesh classes.

Functions

mesh_data_to_meshio(mesh_data)	Convert one normalized planar payload back to a meshio object.
meshio_to_mesh_data(mesh, *[, cell_type])	Convert one meshio mesh into a normalized planar mesh payload.
normalize_cell_type(cell_type)	Normalize external and meshio cell-type names to the internal convention.
read_gmsh_2d_mesh(path, *[, cell_type])	Read one planar 2D triangle or quadrilateral mesh from disk.
write_gmsh_2d_mesh(path, mesh_data, *[, ...])	Write one planar mesh payload to disk through meshio.

Classes

GmshCellBlock(cell_type, connectivity)	One homogeneous 2D cell block read from one mesh file.
GmshMeshData(points_xy, cell_blocks[, ...])	Raw planar mesh payload independent from the higher HydroModPy layers.
