yt.geometry.oct_geometry_handler module

Octree geometry handler

class yt.geometry.oct_geometry_handler.OctreeIndex(ds, dataset_type)[source]

Bases: yt.geometry.geometry_handler.Index

The Index subclass for oct AMR datasets

comm = None
convert(unit)[source]
get_data(node, name)

Return the dataset with a given name located at node in the datafile.

get_dependencies(fields)
get_smallest_dx()[source]

Returns (in code units) the smallest cell size in the simulation.

load_object(name)

Load and return and object from the data_file using the Pickle protocol, under the name name on the node /Objects.

partition_index_2d(axis)
partition_index_3d(ds, padding=0.0, rank_ratio=1)
partition_index_3d_bisection_list()

Returns an array that is used to drive _partition_index_3d_bisection, below.

partition_region_3d(left_edge, right_edge, padding=0.0, rank_ratio=1)

Given a region, it subdivides it into smaller regions for parallel analysis.

save_data(array, node, name, set_attr=None, force=False, passthrough=False)

Arbitrary numpy data will be saved to the region in the datafile described by node and name. If data file does not exist, it throws no error and simply does not save.

save_object(obj, name)

Save an object (obj) to the data_file using the Pickle protocol, under the name name on the node /Objects.
