DataFile

The DataFile class allows you to access solution data without a live Fluent session. You command DataFile objects to read your Fluent data files before you access the data through the DataFile methods.

Sample usage

This example shows how to command a DataFile object to access case and data files, and query its interface:

>>> from ansys.fluent.core import examples
>>> from ansys.fluent.core.filereader.data_file import DataFile
>>> from ansys.fluent.core.filereader.case_file import CaseFile

>>> data_file_name = examples.download_file("elbow1.dat.h5", "pyfluent/file_session")
>>> reader = DataFile(data_file_name=data_file_name, case_file_handle=CaseFile(case_file_name))
>>> reader.case_file
'elbow1.cas.h5'
>>> reader.variables()
{'flow-time': 0.0,
 'solvertime': 43.13454608435059,
 'time-step': 0,
  .....
 'vbm/trim': []}
>>> reader.get_phases()
['phase-1']
>>> reader.get_face_variables("phase-1")
['SV_ARTIFICIAL_WALL_FLAG',
 'SV_D',
 'SV_DENSITY',
  .....
 'SV_WALL_YPLUS_UTAU',
 '']
 >>> reader.get_cell_variables("phase-1")
 ['SV_BF_V',
  'SV_D',
  'SV_DENSITY',
   .....
  'SV_V',
  'SV_W',
  '']
 >>> reader.get_face_scalar_field_data("phase-1", "SV_T", 4)
 array([293.14999, 293.14999, 293.14999, ..., 293.14999, 293.14999,
     293.14999])
 >>> reader.get_face_vector_field_data("phase-1", 4)
 array([ 3.32643010e-01,  6.64311343e-03,  0.00000000e+00, ...,
      4.56052223e-01,  2.45034248e-01, -1.24726618e-15])
