xugrid.Ugrid2d.validate_edge_node_connectivity

Ugrid2d.validate_edge_node_connectivity()

Mark valid edges, by comparing face_node_connectivity and edge_node_connectivity. Edges that are not part of a face, as well as duplicate edges are marked False.

An error is raised if the face_node_connectivity defines more unique edges than the edge_node_connectivity.

Returns:

valid – Marks for every edge whether it is valid.

Return type:

np.ndarray of bool

Examples

To purge invalid edges and associated data from a dataset that contains un-associated or duplicate edges:

>>> uds = xugrid.open_dataset("example.nc")
>>> valid = uds.ugrid.grid.validate_edge_node_connectivity()
>>> purged = uds.isel({grid.edge_dimension: valid})
