export_data

classmethod HDF5.export_data(network=None, phases=[], element=['pore', 'throat'], filename='', interleave=True, flatten=False, categorize_by=[])

Creates an HDF5 file containing data from the specified objects, and categorized according to the given arguments.

Parameters

• network (GenericNetwork) – The network containing the desired data

• phases (list[GenericPhase]s (optional, default is none)) – A list of phase objects whose data are to be included

• element (str or list[str]) – An indication of whether ‘pore’ and/or ‘throat’ data are desired. The default is both.

• interleave (bool (default is True)) – When True (default) the data from all Geometry objects (and Physics objects if phases are given) is interleaved into a single array and stored as a network property (or Phase property for Physics data). When False, the data for each object are stored under their own dictionary key, the structuring of which depends on the value of the flatten argument.

• flatten (bool (default is True)) – When True, all objects are accessible from the top level of the dictionary. When False objects are nested under their parent object. If interleave is True this argument is ignored.

• categorize_by (str or list[str]) –

  Indicates how the dictionaries should be organized. The list can contain any, all or none of the following strings:

  ’objects’ : If specified the dictionary keys will be stored under a general level corresponding to their type (e.g. ‘network/net_01/pore.all’). If interleave is True then only the only categories are network and phase, since geometry and physics data get stored under their respective network and phase.

  ’data’ : If specified the data arrays are additionally categorized by label and property to separate boolean from numeric data.

  ’elements’ : If specified the data arrays are additionally categorized by pore and throat, meaning that the propnames are no longer prepended by a ‘pore.’ or ‘throat.’
