Last update: 31.07.2026

Version: 0.0.0

Description

Reads the pretension adjustment and tension force. Rotation is not allowed for these results.

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 time_scoping scopings_container, scoping
1 mesh_scoping scopings_container, scoping
2 fields_container fields_container
3 streams_container Required streams_container, stream
4 data_sources Required data_sources
7 mesh abstract_meshed_region, meshes_container
14 read_cyclic enum dataProcessing::ECyclicReading, int32
15 expanded_meshed_region abstract_meshed_region, meshes_container
18 sectors_to_expand vector<int32>, scoping, scopings_container
19 phi double

time_scoping (Pin 0)

mesh_scoping (Pin 1)

fields_container (Pin 2)

streams_container (Pin 3)

data_sources (Pin 4)

mesh (Pin 7)

mesh. If cylic expansion is to be done, mesh of the base sector

read_cyclic (Pin 14)

  • Required: No
  • Expected type(s): enum dataProcessing::ECyclicReading, int32

if 0 cyclic symmetry is ignored, if 1 cyclic sector is read, if 2 cyclic expansion is done, if 3 cyclic expansion is done and stages are merged (default is 1)

expanded_meshed_region (Pin 15)

mesh expanded, use if cyclic expansion is to be done.

sectors_to_expand (Pin 18)

sectors to expand (start at 0), for multistage: use scopings container with 'stage' label, use if cyclic expansion is to be done.

phi (Pin 19)

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

angle phi in degrees (default value 0.0), use if cyclic expansion is to be done.

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 adjustment fields_container
1 tension_force fields_container

adjustment (Pin 0)

Adjustment

tension_force (Pin 1)

Tension Force

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.

Category: result

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.
