math:centroid
Last update: 31.07.2026Version: 0.0.0
Description
Computes centroid of field1 and field2, using fieldOut = field1*(1.-fact)+field2*(fact). Only works by index.
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 | fieldA | Required | field, fields_container |
| 1 | fieldB | Required | field, fields_container |
| 2 | factor | Required | double |
fieldA (Pin 0)
- Required: Yes
- Expected type(s):
field,fields_container
field or fields container with only one field is expected
fieldB (Pin 1)
- Required: Yes
- Expected type(s):
field,fields_container
field or fields container with only one field is expected
factor (Pin 2)
- Required: Yes
- Expected type(s):
double
Scalar
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 | field | field |
field (Pin 0)
- Expected type(s):
field
Field with centroid calculation: fieldA*(1-factor) + fieldB*factor
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.
num_threads
- Expected type(s):
int32 - Default value: 0
Number of threads to use to run in parallel
run_in_parallel
- Expected type(s):
bool - Default value: true
Loops are allowed to run in parallel if the value of this config is set to true.
work_by_index
- Expected type(s):
bool - Default value: true
If this option is set to true, loops and comparisons by entity will be done by index instead of ids.

This operator can be accessed through scripting interfaces using these identifiers.

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"); // operator instantiation
op.connect(0, my_fieldA);
op.connect(1, my_fieldB);
op.connect(2, my_factor);
ansys::dpf::Field my_field = op.getOutput<ansys::dpf::Field>(0);
CPython
import ansys.dpf.core as dpf
op = dpf.operators.math.None() # operator instantiation
op.inputs.fieldA.connect(my_fieldA)
op.inputs.fieldB.connect(my_fieldB)
op.inputs.factor.connect(my_factor)
my_field = op.outputs.field()
IPython
import mech_dpf
import Ans.DataProcessing as dpf
op = dpf.operators.math.None() # operator instantiation
op.inputs.fieldA.Connect(my_fieldA)
op.inputs.fieldB.Connect(my_fieldB)
op.inputs.factor.Connect(my_factor)
my_field = op.outputs.field.GetData()
