## Description

When this keyword is present, Dakota will right (some) final method results to disk in HDF5 format instead of just to the console. This is an experimental feature, and the contents and organization of the output file is subject to change. The current organization and a brief explanation of HDF5 is provided in the Dakota HDF5 Output section of this manual.

With `hdf5` selected, the default name of the output file is `dakota_results.h5`. This can be changed using the `results_output_file` keyword.

## Examples

    environment
      results_output
          hdf5
          results_output_file 'my_results'  # The .h5 extension will be added
