Description
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 b 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.)
