mapping:on reduced coordinates

Last update: 31.07.2026

Version: 0.0.0

Description

Evaluates a result on specified reduced coordinates of given elements (interpolates results inside elements with shape functions).

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 reduced_coordinates Required field, fields_container
2 element_ids Required scopings_container
7 mesh abstract_meshed_region, meshes_container
200 use_quadratic_elements bool

fields_container (Pin 0)

reduced_coordinates (Pin 1)

coordinates in the reference elements to find (found with the operator "find_reduced_coordinates")

element_ids (Pin 2)

Ids of the elements where each set of reduced coordinates is found (found with the operator "find_reduced_coordinates")

mesh (Pin 7)

if the first field in input has no mesh in support, then the mesh in this pin is expected (default is false), if a meshes container with several meshes is set, it should be on the same label spaces as the coordinates fields container

use_quadratic_elements (Pin 200)

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

If this pin is set to true, the interpolation is computed on the quadratic element if the element is quadratic (more precise but less performant). Default is false. To use only when results have mid side nodes values.

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)

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.

Scripting

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("interpolation_operator"); // operator instantiation
op.connect(0, my_fields_container);
op.connect(1, my_reduced_coordinates);
op.connect(2, my_element_ids);
op.connect(7, my_mesh);
op.connect(200, my_use_quadratic_elements);
ansys::dpf::FieldsContainer my_fields_container = op.getOutput<ansys::dpf::FieldsContainer>(0);
CPython
import ansys.dpf.core as dpf

op = dpf.operators.mapping.on_reduced_coordinates() # operator instantiation
op.inputs.fields_container.connect(my_fields_container)
op.inputs.reduced_coordinates.connect(my_reduced_coordinates)
op.inputs.element_ids.connect(my_element_ids)
op.inputs.mesh.connect(my_mesh)
op.inputs.use_quadratic_elements.connect(my_use_quadratic_elements)
my_fields_container = op.outputs.fields_container()
IPython
import mech_dpf
import Ans.DataProcessing as dpf

op = dpf.operators.mapping.on_reduced_coordinates() # operator instantiation
op.inputs.fields_container.Connect(my_fields_container)
op.inputs.reduced_coordinates.Connect(my_reduced_coordinates)
op.inputs.element_ids.Connect(my_element_ids)
op.inputs.mesh.Connect(my_mesh)
