math:centroid (fields container)

Last update: 31.07.2026

Version: 0.0.0

Description

Computes the centroid of all the matching fields of a fields container at a given time or frequency, using fieldOut = field1*(1.-fact)+field2*(fact).

Inputs

This table lists the input pins for this operator. Input pins define the data that the operator requires to perform its operation. Some inputs are required, while others are optional and provide additional configuration. Each parameter is detailed in the sections that follow the table.

Pin number Name Status Expected type(s)
0 fields_container Required fields_container
1 time_freq Required double
2 step int32
8 time_freq_support time_freq_support

fields_container (Pin 0)

FieldsContainer with fields for centroid calculation

time_freq (Pin 1)

  • Required: Yes
  • Expected type(s): double

Time or frequency value for field selection

step (Pin 2)

  • Required: No
  • Expected type(s): int32

Optional step specification

time_freq_support (Pin 8)

Optional TimeFreqSupport for field resolution

Outputs

This table lists the output pins for this operator. Output pins provide the results of the operator's computation and can be connected to inputs of other operators or retrieved for further processing. Each output is detailed in the sections that follow the table.

Pin number Name Expected type(s)
0 fields_container fields_container

fields_container (Pin 0)

FieldsContainer with centroid calculation results at specified time/frequency

Configurations

This operator supports configuration options that modify its behavior.

mutex

  • Expected type(s): bool
  • Default value: false

If this option is set to true, the shared memory is prevented from being simultaneously accessed by multiple threads.

permissive

  • Expected type(s): bool
  • Default value: false

If this option is set to true, warning checks (like unit or data sizes) won't be done.

Examples

These examples demonstrate how to use this operator in different programming environments. Each example shows how to instantiate the operator, connect the required inputs, and retrieve the output.

C++ 
#include "dpf_api.h"

ansys::dpf::Operator op("centroid_fc"); // operator instantiation
op.connect(0, my_fields_container);
op.connect(1, my_time_freq);
op.connect(2, my_step);
op.connect(8, my_time_freq_support);
ansys::dpf::FieldsContainer my_fields_container = op.getOutput<ansys::dpf::FieldsContainer>(0);
CPython 
import ansys.dpf.core as dpf

op = dpf.operators.math.None() # operator instantiation
op.inputs.fields_container.connect(my_fields_container)
op.inputs.time_freq.connect(my_time_freq)
op.inputs.step.connect(my_step)
op.inputs.time_freq_support.connect(my_time_freq_support)
my_fields_container = op.outputs.fields_container()
IPython 
import mech_dpf
import Ans.DataProcessing as dpf

op = dpf.operators.math.None() # operator instantiation
op.inputs.fields_container.Connect(my_fields_container)
op.inputs.time_freq.Connect(my_time_freq)
op.inputs.step.Connect(my_step)
op.inputs.time_freq_support.Connect(my_time_freq_support)
my_fields_container = op.outputs.fields_container.GetData()
