Before a model can be simulated it has to be processed / compiled. For large models this can take a while. You can prevent this by saving a model as a processed model:
1. | In the Editor From the File menu, select Save As. |
2. | Choose the extension Processed Model File .emp. |
Now the model is stored in its compile form and you can directly open the simulator.
Note: You cannot edit processed models, so make sure that you always store models using the standard .emx extension.
