Instead of appealing directly to a primary interface, a nested model maps variables to responses by executing a secondary iterator, or a "sub-iterator". In other words, a function evaluation of the primary study consists of a solution of an entire secondary study - potentially many secondary function evaluations.
The sub-iterator in turn operates on a sub-model. The sub-iterator responses may be combined with non-nested contributions from an optional interface specification.
A sub_method_pointer
must be provided in order to specify the method block describing the sub-iterator. The remainder of the model is specified under that keyword.
A optional_interface_pointer
points to the interface specification and optional_interface_responses_pointer
points to a responses specification describing the data to be returned by this interface. This interface is used to provide non-nested data, which is then combined with data from the nested iterator using the primary_response_mapping
. (See the discussions for the sub_method_pointer
and optional_interface_pointer
keywords.)
