uxarray.Grid.face_node_connectivity

property Grid.face_node_connectivity

Connectivity variable representing the indices of nodes (mesh vertices) that define each face.

Each row (i.e., each face) contains at least three node indices and up to a maximum of n_max_face_nodes. In grids with a mix of geometries (e.g., triangles and hexagons), rows containing fewer than n_max_face_nodes indices are padded with the fill value defined in INT_FILL_VALUE. The node indices are stored in counter-clockwise order.

Returns:

face_node_connectivity – An array of shape (n_face, n_max_face_nodes)

Return type:

xarray.DataArray
