Autogenerated DPF operator classes.

class ansys.dpf.core.operators.averaging.elemental_difference.elemental_difference(field=None, mesh_scoping=None, mesh=None, through_layers=None, config=None, server=None)#

Transform ElementalNodal or Nodal field into Elemental field. Each elemental value is the maximum difference between the computed result for all nodes in this element. Result is computed on a given element scoping.

Parameters
  • field (Field or FieldsContainer) – Field or fields container with only one field is expected

  • mesh_scoping (Scoping, optional) – Average only on these entities

  • mesh (MeshedRegion, optional) –

  • through_layers (bool, optional) – The max elemental difference is taken through the different shell layers if true (default is false)

Examples

>>> from ansys.dpf import core as dpf
>>> # Instantiate operator
>>> op = dpf.operators.averaging.elemental_difference()
>>> # Make input connections
>>> my_field = dpf.Field()
>>> op.inputs.field.connect(my_field)
>>> my_mesh_scoping = dpf.Scoping()
>>> op.inputs.mesh_scoping.connect(my_mesh_scoping)

...     through_layers=my_through_layers,
... )
>>> # Get output data
>>> result_field = op.outputs.field()
static default_config(server=None)#

Returns the default config of the operator.

This config can then be changed to the user needs and be used to instantiate the operator. The Configuration allows to customize how the operation will be processed by the operator.

Parameters

server (server.DPFServer, optional) – Server with channel connected to the remote or local instance. When None, attempts to use the the global server.

property inputs#

Enables to connect inputs to the operator

Returns

inputs

Return type

InputsElementalDifference

property outputs#

Enables to get outputs of the operator by evaluationg it

Returns

outputs

Return type

OutputsElementalDifference

property config#

Copy of the operator’s current configuration.

You can modify the copy of the configuration and then use operator.config = new_config or create an operator with the new configuration as a parameter.

Returns

Copy of the operator’s current configuration.

Return type

ansys.dpf.core.config.Config

connect(pin, inpt, pin_out=0)#

Connect an input on the operator using a pin number.

Parameters
  • pin (int) – Number of the input pin.

    Field, FieldsContainer, Scoping, ScopingsContainer, MeshedRegion,

    MeshesContainer, DataSources, Operator, os.PathLike

    Object to connect to.

  • pin_out (int, optional) – If the input is an operator, the output pin of the input operator. The default is 0.

Examples

Compute the minimum of displacement by chaining the "U" and "min_max_fc" operators.

>>> from ansys.dpf import core as dpf
>>> from ansys.dpf.core import examples
>>> data_src = dpf.DataSources(examples.multishells_rst)
>>> disp_op = dpf.operators.result.displacement()
>>> disp_op.inputs.data_sources(data_src)
>>> max_fc_op = dpf.operators.min_max.min_max_fc()
>>> max_fc_op.inputs.connect(disp_op.outputs)
>>> max_field = max_fc_op.outputs.field_max()
>>> max_field.data
array([[0.59428386, 0.00201751, 0.0006032 ]])
eval(pin=None)#

Evaluate this operator.

Parameters

pin (int) – Number of the output pin. The default is None.

Returns

output – Returns the first output of the operator by default and the output of a given pin when specified. Or, it only evaluates the operator without output.

Return type

FieldsContainer, Field, MeshedRegion, Scoping

Examples

Use the eval method.

>>> from ansys.dpf import core as dpf
>>> import ansys.dpf.core.operators.math as math
>>> from ansys.dpf.core import examples
>>> data_src = dpf.DataSources(examples.multishells_rst)
>>> disp_op = dpf.operators.result.displacement()
>>> disp_op.inputs.data_sources(data_src)
>>> normfc = math.norm_fc(disp_op).eval()
get_output(pin=0, output_type=None)#

Retrieve the output of the operator on the pin number.

To activate the progress bar for server version higher or equal to 3.0, use my_op.progress_bar=True

Parameters
  • pin (int, optional) – Number of the output pin. The default is 0.

  • output_type (ansys.dpf.core.common.types, optional) – Requested type of the output. The default is None.

Returns

Output of the operator.

Return type

type

static operator_specification(op_name, server=None)#

Put the grpc spec message in self._spec

property progress_bar: bool#

With this property, the user can choose to print a progress bar when the operator’s output is requested, default is False

run()#
