Save Models

Previous pageReturn to chapter overviewNext page

Models in 20-sim are stored with the extension .emx. You can save an existing model in several ways.

Main Models

1.From the File menu, select Save: This will save the complete model. If no file name is known a Save dialog is opened.
2.From the File menu, select Save As: This is essentially the same as the Save command but now the Save dialog is opened even if a file name is known.
3.From the File menu, select Save a copy As : This is similar to Save As but now a copy of the file is saved instead. This allows the user to keep on working on the model while saving intermediate experiments.

During Save As and Save copy As you can choose various formats to store models:

1.emx: The standard format for 20-sim models
2.emp: The processed format for 20-sim model
3.emz: The packed format. This is a zip file that contains all external files that may be required to run a model.

Submodels

1.From the File menu, select Save Submodel: This will save the submodel that is selected in your Graphical Editor.

Encrypted

1.From the File menu, select Save Encrypted: This will allow you to store a model using encryption. If a submodel was selected, a menu is opened asking you to store the submodel or the complete model.

Encrypted models are useful if you want others to use your 20-sim model, without seeing the underlying equations. If an encrypted model is loaded in 20-sim, the Go Down command does not work on that model. The encrypted model is shown with a lock in the model hierarchy.

Note: You can also encrypt or decrypt models using the Edit menu.

Warning: Once a model is encrypted, you can not decrypt it anymore! So keep cautious that you always store a non-encrypted original.

Processed

1.From the File menu, select Save Encrypted: This will allow you to store a model using encryption. If a submodel was selected, a menu is opened asking you to store the submodel or the complete model.
