filename_prefix

User-customizable portion of exported/imported surrogate model filenames

## Topics

This keyword is related to the topics:

- surrogate_models

## Specification

Alias: none

Argument(s): STRING

Default: exported_surrogate

## Description

Dakota surrogate model files are exported and imported using one file per response, per requested format. The files are named using the pattern `{prefix}`.{response_descriptor}.{extension}. This `filename_prefix` keyword is used to supply the prefix portion of the pattern.

The `response_descriptor` portion of the pattern is filled in using the response descriptors provided by the user (or, if none are specified, descriptors automatically generated by Dakota). Extension is a three or four letter string that depends on the format.

## Examples

This input snippet directs Dakota to write one algebraic format file and one binary archive file for each response. The names of the files will follow the patterns `my_surrogate`.{response_descriptor}.alg (for the algebraic files) and `my_surrogate`.{response_descriptor}.bsps (for the binary files).
