User-customizable portion of exported/imported surrogate model filenames

Topics

surrogate_models

Specification

• Alias: None

• Arguments: 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).
