`deserializer`#

class ansys.dpf.core.operators.serialization.deserializer.deserializer(stream_type=None, file_path=None, config=None, server=None)#

Bases: ansys.dpf.core.dpf_operator.Operator

Takes a file generated by the serializer and deserializes it into DPF’s entities.

Parameters:

stream_type (int) – 0 for ASCII (default), and 1 for binary
file_path (str) – file path

Returns:

any_output1 (Any) – number and types of outputs corresponding of the inputs used in the serialization
any_output2 (Any) – number and types of outputs corresponding of the inputs used in the serialization

Examples

>>> from ansys.dpf import core as dpf

>>> # Instantiate operator
>>> op = dpf.operators.serialization.deserializer()

>>> # Make input connections
>>> my_stream_type = int()
>>> op.inputs.stream_type.connect(my_stream_type)
>>> my_file_path = str()
>>> op.inputs.file_path.connect(my_file_path)

>>> # Instantiate operator and connect inputs in one line
>>> op = dpf.operators.serialization.deserializer(
...     stream_type=my_stream_type,
...     file_path=my_file_path,
... )

>>> # Get output data
>>> result_any_output1 = op.outputs.any_output1()
>>> result_any_output2 = op.outputs.any_output2()

Property detail#

property deserializer.inputs: InputsDeserializer#

Enables to connect inputs to the operator

Returns:: An instance of InputsDeserializer.
Return type:: inputs

property deserializer.outputs: OutputsDeserializer#

Enables to get outputs of the operator by evaluating it

Returns:: An instance of OutputsDeserializer.
Return type:: outputs

property deserializer.progress_bar: bool#

Enable or disable progress bar display when requesting the operator’s output.

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

property deserializer.config#

Copy of the operator’s current configuration.

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

For information on an operator’s options, see the documentation for that operator.

Returns:: Copy of the operator’s current configuration.
Return type:: ansys.dpf.core.config.Config

Examples

Modify the copy of an operator’s configuration and set it as current config of the operator.

>>> from ansys.dpf import core as dpf
>>> op = dpf.operators.math.add()
>>> config_add = op.config
>>> config_add.set_work_by_index_option(True)
>>> op.config = config_add

property deserializer.id: int#

Retrieve the unique identifier of the operator.

This property returns the unique ID associated with the operator. This property is lazily initialized.

Returns:: The unique identifier of the operator.
Return type:: int

Notes

Property available with server’s version starting at 10.0.

property deserializer.specification#

Returns the Specification (or documentation) of this Operator.

Return type:: Specification

Method detail#

static deserializer.default_config(server: ansys.dpf.core.server_types.AnyServerType = None) → ansys.dpf.core.config.Config#

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 with channel connected to the remote or local instance. When None, attempts to use the global server.
Returns:: A new Config instance equivalent to the default config for this operator.
Return type:: config

deserializer.connect(pin, inpt, pin_out=0)#

Connect an input on the operator using a pin number.

Parameters:

pin (int) – Number of the input pin.
inpt (str, int, double, bool, list[int], list[float], Field, FieldsContainer, Scoping,)
ScopingsContainer – Operator, os.PathLike Object to connect to.
MeshedRegion – Operator, os.PathLike Object to connect to.
MeshesContainer – Operator, os.PathLike Object to connect to.
DataSources – Operator, os.PathLike Object to connect to.
CyclicSupport – Operator, os.PathLike Object to connect to.
dict – Operator, os.PathLike Object to connect to.
Outputs – 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.find_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()

op (ansys.dpf.core.dpf_operator.Operator) – Requested type of the output. The default is None.

deserializer.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:

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

Returns:
