Identity mapping of sub-method results to top-level responses


.. toctree::
   :hidden:
   :maxdepth: 1



**Specification**

- *Alias:* None

- *Arguments:* None

- *Default:* no sub-iterator contribution to nested model functions


**Description**


Specifies that the list of sub-method results (statistics, best
parameters, etc.) should map one-to-one to the list of top-level
nested model responses.

*Usage Tips*

To use an identity mapping, the number of top-level nested model
responses (primary + secondary responses) must equal the number of
sub-method results. If receiving an error about this, set ``output``
``verbose`` and re-run the Dakota study to see a list of sub-method
results responses.

The identity map may not be used in conjunction with
:dakkw:`model-nested-optional_interface_pointer`, nor with an explicit
``primary_response_mapping`` or ``secondary_response_mapping``.



**Examples**



.. code-block::

    model
      id_model 'nested'
        nested
        sub_method_pointer 'aleat'
        identity_response_mapping
