Saving Models

When you save a model, the model's information is saved in two separate files: a model file (.ITMX or .STMX) and a database file (.ISDB).

Note: If you share your model by sending the model file to someone else and you want to include the model's simulation results, you also need to send the database (.ISDB) file. For more information about the files you need to include when you share your models, see Distributing Models to Users.

Note: If you're using modules, see Saving Changes to Modules for options on how modules are saved.

To Save a Model

  1. From the File menu, choose Save.

    If you've saved this model before, Stella will save the changes to your model in the same model and database files.

    If you've never saved this model before, the Save File As dialog box will open.

    If you're saving a model that was converted from an older version of Stella when you opened it, the Save File As dialog box will open.

  2. Specify the location and name for the model file.
  3. Click Save.

    The model file will be saved with the name and to the location you specified.

    If there are saved runs for the model, a database file will also be saved to the location you specified, with the same name as the model file.

    Note: If you're saving a model created with a version of Stella that's older than Version 10, the model will be saved with the new .ITMX or .STMX extension. You can't save a model as an earlier version.

To Make a Copy of a Model

Use the Save As command to save a copy of the currently open model as a new model.

  1. From the File menu, choose Save As.

    The Save File As dialog box will open.

  2. Specify the location and name for the new model file.
  3. Click Save.

    The new model file will be saved with the name and to the location you specified.

    If there are saved runs for the model, a database file will also be saved to the location you specified, with the same name as the model file.

    Note: If you're saving a model created with a version of Stella that's older than Version 10, the model will be saved with the new .ITMX or .STMX extension. You can't save a model as an earlier version.
