## Description

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 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.
