static default_config()

Returns the default config for a given operator. This config can then be changed to the user needs and be used to instantiate the given operator

Parameters
  • name (str) – Name of the operator. For example ‘U’.

  • 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

property config

Returns a copy of the current config of the operator. To use the config that you modify, please use operator.config = new_config or create an operator with the new config as a parameter.

Config

connect(pin, inpt, pin_out=0)

Connect an input on the operator using a pin number.

Parameters

Examples

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

property fields_containerA

Allows to connect fields_containerA input to the operator

Parameters

my_fields_containerA (FieldsContainer,) –

Examples

>>> from ansys.dpf import core as dpf
>>> op = dpf.operators.logic.identical_fc()
>>> op.inputs.fields_containerA.connect(my_fields_containerA)
>>> #or
>>> op.inputs.fields_containerA(my_fields_containerA)
property fields_containerB

Allows to connect fields_containerB input to the operator

Parameters

my_fields_containerB (FieldsContainer,) –

property tolerance

Allows to connect tolerance input to the operator

  • pindoc: Double relative tolerance. Maximum tolerance gap between to compared values: values within relative tolerance are considered identical (v1-v2)/v2 < relativeTol (default is 0.001).
