flopy.mf6.data.mfdataarray module

class MFArray(sim_data, model_or_sim, structure, data=None, enable=True, path=None, dimensions=None)[source]

Bases: flopy.mf6.data.mfdata.MFMultiDimVar

  • structure (MFDataStructure) – describes the structure of the data
  • data (list or ndarray) – actual data
  • enable (bool) – enable/disable the array
  • path (tuple) – path in the data dictionary to this MFArray
  • dimensions (MFDataDimensions) – dimension information related to the model, package, and array

Sets the contents of the data at layer layer to data with multiplier multiplier. For unlayered data do not pass in layer. Data can have the following formats: 1) ndarray - numpy ndarray containing all of the data 2) [data] - python list containing all of the data 3) val - a single constant value to be used for all of the data 4) {‘filename’:filename, ‘factor’:fct, ‘iprn’:print, ‘data’:data} - dictionary defining external file information 5) {‘data’:data, ‘factor’:fct, ‘iprn’:print) - dictionary defining internal information. Data that is layered can also be set by defining a list with a length equal to the number of layers in the model. Each layer in the list contains the data as defined in the formats above:

[layer_1_val, [layer_2_array_vals], {‘filename’:file_with_layer_3_data, ‘factor’:fct, ‘iprn’:print}]
