resqpy.derived_model.add_edges_per_column_property_array(epc_file, a, property_kind, grid_uuid=None, source_info='imported', title=None, discrete=False, uom=None, time_index=None, time_series_uuid=None, string_lookup_uuid=None, null_value=None, facet_type=None, facet=None, realization=None, local_property_kind_uuid=None, extra_metadata={}, new_epc_file=None)

Adds an edges per column grid property from a numpy array to an existing resqml dataset.

  • epc_file (string) – file name to load model resqml model from (and rewrite to if new_epc_file is None)

  • a (3D numpy array) – the property array to be added to the model; expected shape (nj,ni,2,2) or (nj,ni,4)

  • property_kind (string) – the resqml property kind

  • grid_uuid (uuid object or string, optional) – the uuid of the grid to which the property relates; if None, the property is attached to the ‘main’ grid

  • source_info (string) – typically the name of a file from which the array has been read but can be any information regarding the source of the data

  • title (string) – this will be used as the citation title when a part is generated for the array; for simulation models it is desirable to use the simulation keyword when appropriate

  • discrete (boolean, default False) – if True, the array should contain integer (or boolean) data; if False, float

  • uom (string, default None) – the resqml units of measure for the data; not relevant to discrete data

  • time_index (integer, default None) – if not None, the time index to be used when creating a part for the array

  • time_series_uuid (uuid object or string, default None) – required if time_index is not None

  • string_lookup_uuid (uuid object or string, optional) – required if the array is to be stored as a categorical property; set to None for non-categorical discrete data; only relevant if discrete is True

  • null_value (int, default None) – if present, this is used in the metadata to indicate that this value is to be interpreted as a null value wherever it appears in the data (use for discrete data only)

  • facet_type (string) – resqml facet type, or None

  • facet (string) – resqml facet, or None

  • realization (int) – realization number, or None

  • local_property_kind_uuid (uuid.UUID or string) – uuid of local property kind, or None

  • extra_metadata (dict, optional) – any items in this dictionary are added as extra metadata to the new property

  • new_epc_file (string, optional) – if None, the source epc_file is extended with the new property object; if present, a new epc file (& associated h5 file) is created to contain a copy of the grid and the new property


uuid.UUID - the uuid of the newly created property


the RESQML protocol for saving edges per column properties uses a clockwise ordering of the 4 edges of a column; the resqpy protocol uses 2 dimensions of extent 2, being the axis (J, I) and face (-, +); this function assumes the array is in RESQML protocol if it has shape (nj, ni, 4) and resqpy protocol if it has shape (nj, ni, 2, 2); when reloading the property it will be presented in RESQML protocol; calling code can use property module functions reformat_column_edges_from_resqml_format() and reformat_column_edges_to_resqml_format() to convert between the protocols if needed
