Field info#

You can use field info objects to access Fluent field information.

Accessing field info objects#

>>> import ansys.fluent.core as pyfluent
>>> solver = pyfluent.launch_fluent(mode="solver")
>>>"case-dats", file_name=mixing_elbow_case_path)
>>> solver.solution.initialization.hybrid_initialize()

The field info object is an attribute of the solver object:

>>> field_info = solver.field_info

Sample requests#

Here are the methods for requesting field information:

  • get_fields_info for getting fields information.

  • get_range for getting the range of the field.

  • get_vector_fields_info for getting vector fields information.

  • get_surfaces_info for getting the surfaces information.

Get fields info#

You can request the fields information (field name, domain, and section) by calling the get_fields_info method.

>>> field_info.get_fields_info()
{'pressure': {'display_name': 'Static Pressure', 'section': 'Pressure...', 'domain': 'mixture'},
 'pressure-coefficient': {'display_name': 'Pressure Coefficient', 'section': 'Pressure...', 'domain': 'mixture'},
 'dynamic-pressure': {'display_name': 'Dynamic Pressure', 'section': 'Pressure...', 'domain': 'mixture'},
 'absolute-pressure': {'display_name': 'Absolute Pressure', 'section': 'Pressure...', 'domain': 'mixture'},

Get range#

You can request the range (minimum and maximum values) for a given field by calling the get_range method. It takes a field argument which can be obtained from the keys of the dictionary returned by get_fields_info method.

>>> field_info.get_range("velocity")
[0.0, 0.0]
>>> field_info.get_range("cell-weight")
[8.0, 24.0]

Get vector fields info#

You can request the vector fields information by calling the get_vector_fields_info method.

>>> field_info.get_vector_fields_info()
{'velocity': {'x-component': 'x-velocity', 'y-component': 'y-velocity', 'z-component': 'z-velocity'},
 'relative-velocity': {'x-component': 'relative-x-velocity', 'y-component': 'relative-y-velocity', 'z-component': 'relative-z-velocity'}}

Get surfaces info#

You can request the surfaces information (surface name, ID, and type) by calling the get_surfaces_info method.

>>> field_info.get_surfaces_info()
{'symmetry-xyplane': {'surface_id': [5], 'zone_id': 29, 'zone_type': 'symmetry', 'type': 'zone-surf'},
 'hot-inlet': {'surface_id': [4], 'zone_id': 30, 'zone_type': 'velocity-inlet', 'type': 'zone-surf'},
 'cold-inlet': {'surface_id': [3], 'zone_id': 31, 'zone_type': 'velocity-inlet', 'type': 'zone-surf'},
 'outlet': {'surface_id': [2], 'zone_id': 32, 'zone_type': 'pressure-outlet', 'type': 'zone-surf'},
 'wall-inlet': {'surface_id': [1], 'zone_id': 33, 'zone_type': 'wall', 'type': 'zone-surf'},
 'wall-elbow': {'surface_id': [0], 'zone_id': 34, 'zone_type': 'wall', 'type': 'zone-surf'}}
