file_tag

Tag each parameters & results file name with the function evaluation number

## Specification

Alias: none

Argument(s): none

Default: no tagging

## Description

If this keyword is used, Dakota will append a period and the function evaluation number to the names of the parameter and results files.

Default Behavior If this keyword is omitted, the default is no file tagging.

Usage Tips

- File tagging is most useful when multiple function evaluations are running simultaneously using files in a shared disk space. The analysis driver will be able to infer the function evaluation number from the file names.
- Note that when the `file_save` keyword is used, Dakota automatically renames parameters and results files, giving them tags after execution of the analysis driver if they otherwise would be overwritten by the next evaluation.

## Examples

If the following is included in the `interface` section of the Dakota input:

      parameters_file = params.in
      results_file = results.out
      file_tag

Then for the 3rd evaluation, Dakota will write `params.in.3`, and will expect `results.out.3` to be written by the analysis driver.
