21 | This model illustrates how variables are declared and relations written. |

22 | The model contains no initialisation for any of the variable values, and |

23 | does not specify which variables are 'fixed' and which ones should be |

24 | solved for. For this reason, when loaded, this model will cause problems |

25 | that ASCEND will attempt to resolve through warnings to the user. |
