get_fields_by_time_complex_ids(timeid=None, complexid=None)#

Retrieve fields at a requested time ID or complex ID.

Parameters:

  • timeid (int, optional) – Time ID or frequency ID, which is the one-based index of the result set.

  • complexid (int, optional) – Complex ID, where 1 is for imaginary and 0 is for real.

Returns:

fields – Fields corresponding to the request.

Return type:

list[Field]

Examples

Extract the fifth time set of a transient analysis.

>>> from ansys.dpf import core as dpf
>>> from ansys.dpf.core import examples
>>> transient = examples.download_transient_result()
>>> model = dpf.Model(transient)
>>> len(model.metadata.time_freq_support.time_frequencies)
35
>>> disp = model.results.displacement()
>>> disp.inputs.time_scoping.connect([1,5])
>>> fields_container = disp.outputs.fields_container()
>>> field_set_5 =fields_container.get_fields_by_time_complex_ids(5)
get_imaginary_field(timeid=None)#

Retrieve the complex field at a requested time.

Parameters:

timeid (int, optional) – Time ID, which is the one-based index of the result set.

Returns:

fields – Field corresponding to the request.

Return type:

Field

get_imaginary_fields(timeid=None)#

Retrieve the complex fields at a requested time.

Parameters:

timeid (int, optional) – Time ID, which is the one-based index of the result set.

Returns:

fields – Fields corresponding to the request.

Return type:

list[Field]

get_label_scoping(label='time')#

Retrieve the scoping for an input label.

This method allows you to retrieve a list of IDs for a given input label in the collection. For example, if the label el_type exists in the collection, you can use the get_lable_scoping method to retrieve a list of IDS with this label. You can then use these IDs to request a given entity inside the collection.

Parameters:

label (str) – Name of the input label.

Returns:

scoping – IDs scoped to the input label.

Return type:

Scoping

get_label_space(index)#

Retrieve the label space of an entry at a requested index.

Parameters:

index (int) – Index of the entry.

Returns:

label_space – Scoping of the requested entry. For example, {"time": 1, "complex": 0}.

Return type:

dict(str:int)

get_time_scoping()#

Retrieves the time scoping containing the time sets.

Returns:

scoping – Scoping containing the time set IDs available in the fields container.

Return type:

Scoping

has_label(label)#

Check if a collection has a specified label.

Parameters:

label (str) – Label to search for. For example, "time".

Returns:

True when successful, False when failed.

Return type:

bool

Examples

>>> from ansys.dpf import core as dpf
>>> coll = dpf.FieldsContainer()
>>> coll.add_label('time')
>>> coll.has_label('time')
True

>>> coll.has_label('complex')
False
static integral_collection(inpt, server: ansys.dpf.core.server_types.BaseServer | None = None)#

Creates a collection of integral type with a list.

The collection of integral is the equivalent of an array of data sent server side. It can be used to efficiently stream large data to the server.

Parameters:

inpt (list[float], list[int], numpy.array) – list to transfer server side

Return type:

IntegralCollection

Notes

Used by default by the 'Operator' and the``’Workflow’`` when a list is connected or returned.

property labels: list#

Retrieve labels scoping the collection.

Returns:

labels – List of labels that entries are scoped to. For example, ["time", "complex"].

Return type:

list[str]

property name#

Name of the Collection.

Notes

Available starting with DPF 2024 R2 pre0.

Return type:

str

plot(label_space: dict | None = None, **kwargs)#

Plots the fields in the FieldsContainer for the given LabelSpace. Check the labels available for the FieldsContainer with labels().

Parameters:

  • label_space (Optional[dict], default: None) – A dictionary (LabelSpace) of labels of the FieldsContainer with associated values to select for plotting. This is used to filter the data to plot, for example: - if label_space={'time': 10}: a single time step (mandatory for transient) - if label_space={'complex': 0, 'part': 12}: real part of complex data for a part See get_fields(). If None is given, it renders all fields available, which may not make sense.

  • **kwargs – For more information on accepted keyword arguments, see plot() and DpfPlotter.

select_component(index)#

Select fields containing only the component index.

Fields can be selected only by component index as multiple fields may contain a different number of components.

Parameters:

index (int) – Index of the component.

Returns:

fields – Fields container with one component selected in each field.

Return type:

FieldsContainer

Examples

Select using a component index.

>>> from ansys.dpf import core as dpf
>>> from ansys.dpf.core import examples
>>> transient = examples.download_transient_result()
>>> model = dpf.Model(transient)
>>> disp = model.results.displacement()
>>> disp.inputs.time_scoping.connect([1,5])
>>> fields_container = disp.outputs.fields_container()
>>> disp_x_fields = fields_container.select_component(0)
>>> my_field = disp_x_fields[0]
set_labels(labels)#

Set labels for scoping the collection.

Parameters:

labels (list[str], optional) – Labels to scope entries to. For example, ["time", "complex"].

property time_freq_support#

Time frequency support.
