WRITE TO FILE

WRITE TO FILE

Writes a group of curves out to a file for later use if required. The user is prompted for the list of curves to write out after a filename has been specified.

FILE FORMAT

Writes a group of curves out to a file for later use if required. The user is prompted for the list of curves to write out after a filename has been specified.

T/HIS .cur format This option will write out curves using the default T/HIS curve format. One curve file will be written containing all the selected curves along with their Titles, Axis Labels, Line Labels and styles. From version 9.4 onwards the curve file can also contain information on the UNIT system and the X and Y axis units for each curve (see Appendix B for more details on the curve file format)
Ansys LS-DYNA Keyword One file will be written containing all the selected curves using the Ansys LS-DYNA *DEFINE_CURVE format so that the file is suitable for inclusion in a Ansys LS-DYNA keyword file.
NASTRAN TABLE D1 This option will write out curves using the NASTRAN TABLE D1 format. Curves are listed sequentially in the file.
CSV X,Y,X,Y,X,Y This option will write out curves using as a CSV (comma separated variable) file that can be read into other programs like Microsoft EXCEL. The columns written are x-values for the 1st selected curve, y-values for the 1st selected curve, x-values for the 2nd selected curve, y-values for the 2nd selected curve ...
CSV X,Y,Y,Y,Y,Y

This option also writes out a CSV file. All the curves are output using a single consistent set of X values that can either be taken from one of the curves or they can be generated automatically. 



Summary Gives a summary of the curve. This includes the type of data being plotted and the maximum and minimum values in the curve.
Summary (CSV) CSV (comma separated variable) version of the summary file.
ISO-MME

The ISO-MME format (ISO/TS 13499) is a data exchange format for crash analyses comprising a number of folders and files. Two methods exist based on the type of data source used: Curves or Models. Selecting Curves launches the Curve to ISO-MME script for export configuration which requires user input to select the curves and other options. Selecting Models requires choosing a model for T/HIS to extract the data from and provide a configuration file to specify what data should be written out.

This extra configuration is needed because the naming conventions of the output files, set out in the ISO standard, follow specific rules which require extra data that isn't present in the curves alone and they also contain lines at the top of the files which describe the data in more detail. The contents of the configuration file are described in ISO-MME Configuration File.

In addition, an output directory is specified rather than a output file since multiple files are written out.

A side by side comparison of the panel for output format ISO-MME with Data Source set to Curves and Models is shown below:

And this is how the Curve to ISO-MME script popup that appears when the "Next" button is pressed looks like.

From version 9.4 onwards the CSV files generated by T/HIS can also contain information on the UNIT system and the X and Y axis units for each curve. If you don't want to output this information then you can turn it off.

The default setting for this option can be set via the preference option

this*write_csv_units:

This option can also be turned on and off in FAST-TCF scripts (see FAST-TCF)


ISO-MME Configuration File

The ISO-MME configuration file is a JSON format file which is used to tell T/HIS which curves to generate: the data to extract, from which entities to extract it, their locations in the model and whether any filtering or operations are required. This configuration file is required so T/HIS can write various ISO-MME files with the correct names and any additional data required at the top of the files.

To set the scene, the structure of the directory where various files get written out and the files it contains is:

ISO-MME Version 1.6  ISO-MME Version 2.0

Configuration structure  

Below is an illustration of the configuration file structure. 

  • Test data: At the top of the file is a list of test data properties, followed by a list of descriptors for the test.
  • Objects array: Next is a list of objects (e.g. vehicles, dummies, barriers) and their properties and descriptors. 

Channels and Operations arrays are used to specify the Curve properties to output required curves:

  • Channels array: Each channel in the array is defined as an object with properties such as entityType, id, etc. to create a single curve with its ISO-MME channel code defined in properties like mainLocation, fineLocation etc.
  • Operations array: Each operation object defines an operation to be performed on any previously defined or multiple curves. Operations can be chained together. The final output should be an ISO-MME channel code.

write   An option to select whether the curve should be written to ISO-MME format. 

Acceptable values are 'true' and 'false'. The default case is taken as true. 

 

If set to false, at the end of the ISO-MME writing process in FAST-TCF, the curve is deleted.   

true   Boolean   Optional  
testObjectHeaderNumber

Variable to specify test Object Number

 

Any alphanumeric character

 

First Letter of the ISO-Code String Optional

Operation Data properties 

Some ISO-MME channels can be written directly from the Ansys LS-DYNA results data. However, many require further operations, for example to apply filtering or convert a rotation sensor to a displacement. Each operation takes one or more inputs, uses FAST-TCF to perform the underlying operation, and produces an output. You can “chain” several operations together to produce the desired final output. Intermediate outputs can be given any name; the final output names must match the desired ISO-MME channel code. The following table lists the properties required to define each operation.  

Property    Description    Valid values    Default    Type    Necessity   
operation   The type of operation to be performed on the input curves.   The accepted values for the operation are FAST-TCF Operation values as mentioned in Section 7.8 operation commands (e.g. "muly", "add").  -  String   Required  
input   To process operations by FAST-TCF File, T/HIS requires arguments based on the type of operation.  

Accepted inputs are ISO-MME channel codes for already created curves in the channel block or output curves created in Operation Block, or Numerical Values. 

 

The elements in the Input array are required to be in same order as mentioned in FAST-TCF Manual 7.8.  

 

Eg:- [ "11ABRIRI02WSAN#0", 1.570796]    

 -  Array of strings or Numbers    Required  
output   The output property is used to specify the FAST-TCF curve tag.  

 For intermediate operation outputs, this can be any string.  

For the final output, this should be a valid ISO-MME channel code. 

Eg:- "intermediate curve" or ”11ABRIRI02WSANZC” 

 -  String    Required  
write   An option to select whether the curve should be outputted. 

Acceptable values are 'true' and 'false'. The default case is taken as true. 

 

If set to false, at the end of the ISO-MME writing process in FAST-TCF, the curve is deleted.   

true   Boolean   

Optional
