DPF Framework 2026 R1

metadata:real constants provider

Last update: 31.07.2026

Version: 0.0.0

Description

Reads real constants from the result files contained in the streams or data sources.

Supported file types

This operator supports the following keys (file formats) for each listed namespace (plugin/solver):

  • mapdl: rst, rstp, rth

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)
1 solver_real_constants_ids int32, vector<int32>
3 streams streams_container
4 data_sources Required data_sources

solver_real_constants_ids (Pin 1)

Real Constant ids to recover used by the solver. If not set, all available real constants to be recovered.

streams (Pin 3)

Result file container allowed to be kept open to cache data.

data_sources (Pin 4)

Result file path container, used if no streams are set.

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 real_constants field

real_constants (Pin 0)

  • Expected type(s): field

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.

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("real_constants_provider"); // operator instantiation
op.connect(1, my_solver_real_constants_ids);
op.connect(3, my_streams);
op.connect(4, my_data_sources);
ansys::dpf::Field my_real_constants = op.getOutput<ansys::dpf::Field>(0);
CPython
import ansys.dpf.core as dpf

op = dpf.operators.metadata.real_constants_provider() # operator instantiation
op.inputs.solver_real_constants_ids.connect(my_solver_real_constants_ids)
op.inputs.streams.connect(my_streams)
op.inputs.data_sources.connect(my_data_sources)
my_real_constants = op.outputs.real_constants()
IPython
import mech_dpf
import Ans.DataProcessing as dpf

op = dpf.operators.metadata.real_constants_provider() # operator instantiation
op.inputs.solver_real_constants_ids.Connect(my_solver_real_constants_ids)
op.inputs.streams.Connect(my_streams)
op.inputs.data_sources.Connect(my_data_sources)
my_real_constants = op.outputs.real_constants.GetData()
