`zoomy_core.mesh.mesh_util`#

Reference-element geometry (face order, normals, areas, volumes, inradii) for the supported cell types, used by BaseMesh.

`convert_mesh_type_to_meshio_mesh_type`	Map a Zoomy cell type (`wface` = wedge) to the meshio cell-type name.
`get_extruded_mesh_type`	Cell type obtained by extruding `mesh_type` one layer (line -> quad, triangle -> wface, quad -> hexahedron).
`get_global_cell_index_from_vertices`	Index (plus `offset`) of the first cell, or of all cells if `return_first` is False, containing every vertex in `coordinates`.
`get_element_neighbors`	Elements sharing a face with `current_elem`; returns `(n_found, neighbour_indices, local_face_indices)`.
`face_normals`	Unit normals of the faces of one element, `(n_faces, 3)`; orientation follows the vertex order.
`face_areas`	Area (length in 2D) of each face of one element.
`center`	Vertex-average centre of `element`.
`volume`	Volume (area in 2D, length for lines) of one element of `mesh_type`.
`inradius`	Inradius of one element of `mesh_type`.
`edge_length`	Euclidean length of `edge`.
`find_edge_index`	Local index of the edge/face of `element` whose vertices lie in `edge_vertices`.
`compute_subvolume`	Volume of the sub-simplex spanned by a face and the cell centre (length, triangle, tetrahedron or pyramid for dim 1, 2, 3).
