result:spectrum data

Version: 0.0.0

Description

Read spectral data 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: mode, prs

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.

streams (Pin 3)

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

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

data_sources (Pin 4)

• Required: Yes
• Expected type(s): data_sources

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.

participation_factors (Pin 0)

• Expected type(s): fields_container

Fields container holding participation factors.

mode_coefficients (Pin 1)

• Expected type(s): fields_container

Fields container holding mode coefficients (PRS File).

damping_ratios (Pin 2)

• Expected type(s): fields_container

Fields container holding damping ratios (PRS File).

global_damping (Pin 3)

• Expected type(s): fields_container

Fields container holding for each spectrum: Global Damping Ratio, Damping Stiffness Coefficient & Damping Mass Coefficient (PRS File).

missing_mass (Pin 4)

• Expected type(s): fields_container

Fields container holding for each spectrum: Missing Mass Mode (0: None, 1: Active), Missing Mass Effect ZPA (PRS File).

rigid_response (Pin 5)

• Expected type(s): fields_container

Fields container holding for each spectrum: Rigid Response Mode (0: None, 1: Gupta, 2: Lindley), Freq Begin (Gupta) / ZPA (Lindley), Freq End (Gupta) (PRS File).

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.

Category: result

Plugin: mapdl

Scripting name: spectrum_data

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.
