## Specification

Alias: simulation

Argument(s): none

Default: N/A ( single if no model specification)

## Description

The single model is the simplest model type. It uses a single interface instance to map variables into responses. There is no recursion in this case.

The optional interface_pointer specification identifies the interface block by cross-referencing with the `id_interface` string input from a particular interface keyword specification. This is only necessary when the input file has multiple interface blocks, and you wish to explicitly point to the desired block. The same logic follows for responses and variables blocks and pointers.

## Examples

The example shows a minimal specification for a single model, which is the default model when no models are specified by the user.

    model
      single

This example does not provide any pointer strings and therefore relies on the default behavior of constructing the model with the last variables, interface, and responses specifications parsed.
