By default, this dialog appears when you open a new model file. You can stop it from appearing by unchecking Run Period for new Model in the Options menu.
Model Start Date
The date when the model run begins.
Either a calendar year, e.g., 1999 (implying 1 Jan 1999), or a fully-qualified date if you want to model in financial years, e.g., 5 Apr 2001.
Default: Y1.
Model Run Length
The number of years for which model results are calculated, measured in years from the Model Start Date. There is no specific limit on the length of the model run, other than the disk space required to save the results. However, there is probably little point modelling scenarios beyond a certain time span.
Default: 10. From Model Start Date to year ten inclusive.
Include Year Zero
A choice governing the inclusion of a base or reference period immediately preceding the Model Start Date which allows you to capture initial conditions.
Default: Yes.
