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
