Subsets of elements¶

These methods are useful in identifying subsets of grid elements, e.g., closest node to a point; nodes at edges.

Raster

`cells_at_corners_of_grid`	Get array of cells in cellular grid (grid with only cells) corners.
`find_nearest_node`	Node nearest a point.
`grid_coords_to_node_id`	Convert node indices to node ID.
`is_point_on_grid`	Check if a point is on the grid.
`nodes_around_point`	Get the nodes surrounding a point.
`set_closed_boundaries_at_grid_edges`	Set boundary not to be closed.
`set_fixed_value_boundaries_at_grid_edges`	Create fixed values boundaries.
`set_looped_boundaries`	Create wrap-around boundaries.
