The environment section in a Dakota input file is optional. It specifies the top-level solution environment, optionally including run modes, output controls, and identification of the primary iterative method (top_method_pointer). The output-related keywords address graphics, generation of tabular and results data, and precision of numerical output.

Run Mode Defaults

Dakota run phases include check, pre_run, run, and post_run. The default behavior is to pre_run, run, and post_run, though any or all of these may be specified to select specific run phases. Specifying check will cause Dakota to exit before any selected run modes.
