 # min\_max:over label

 Last update: 31.07.2026 

**Version: 0.0.0**

## Description

Create two fields (0 min 1 max) by looping over the fields container in input and taking the min/max value by component through all the fields having the same id for the label set in input (in pin 1). If no label is specified or if the specified label doesn't exist, the operation is done over all the fields. The fields out are located on the label set in input, so their scoping are the labels ids.For each min max value, the label id for one other fields container labels is kept and returned in a scoping in pin 2 (min) and 3 (max).The field's scoping ids of the value kept in min max are also returned in the scopings in pin 4 (min) and 5 (max).

## 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.

### fields\_container (Pin 0)

- **Required:** Yes
- **Expected type(s):** [`fields_container`](../../core-concepts/dpf-types.md#fields-container)

<a id="input_1"></a>

### label (Pin 1)

- **Required:** Yes
- **Expected type(s):** [`string`](../../core-concepts/dpf-types.md#standard-types)

label name from the fields container

## 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.

## Configurations

This operator supports [configuration options](../../core-concepts/operator-configurations.md) that modify its behavior.

### [mutex](../../core-concepts/operator-configurations.md#mutex)

- **Expected type(s):** [`bool`](../../core-concepts/dpf-types.md#standard-types)
- **Default value:** false

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

## 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++```cpp
#include "dpf_api.h"

ansys::dpf::Operator op("min_max_over_label_fc"); // operator instantiation
op.connect(0, my_fields_container);
op.connect(1, my_label);
ansys::dpf::Field my_field_min = op.getOutput<ansys::dpf::Field>(0);
ansys::dpf::Field my_field_max = op.getOutput<ansys::dpf::Field>(1);
ansys::dpf::Scoping my_domain_ids_min = op.getOutput<ansys::dpf::Scoping>(2);
ansys::dpf::Scoping my_domain_ids_max = op.getOutput<ansys::dpf::Scoping>(3);
ansys::dpf::Scoping my_scoping_ids_min = op.getOutput<ansys::dpf::Scoping>(4);
ansys::dpf::Scoping my_scoping_ids_max = op.getOutput<ansys::dpf::Scoping>(5);

```

CPython```python
import ansys.dpf.core as dpf

op = dpf.operators.min_max.None() # operator instantiation
op.inputs.fields_container.connect(my_fields_container)
op.inputs.label.connect(my_label)
my_field_min = op.outputs.field_min()
my_field_max = op.outputs.field_max()
my_domain_ids_min = op.outputs.domain_ids_min()
my_domain_ids_max = op.outputs.domain_ids_max()
my_scoping_ids_min = op.outputs.scoping_ids_min()
my_scoping_ids_max = op.outputs.scoping_ids_max()

```

IPython```python
import mech_dpf
import Ans.DataProcessing as dpf

op = dpf.operators.min_max.None() # operator instantiation
op.inputs.fields_container.Connect(my_fields_container)
op.inputs.label.Connect(my_label)
my_field_min = op.outputs.field_min.GetData()
my_field_max = op.outputs.field_max.GetData()
my_domain_ids_min = op.outputs.domain_ids_min.GetData()
my_domain_ids_max = op.outputs.domain_ids_max.GetData()
my_scoping_ids_min = op.outputs.scoping_ids_min.GetData()
my_scoping_ids_max = op.outputs.scoping_ids_max.GetData()

```
