About saving
When you are modelling data in PhixFlow, you will be making changes
- to a model, the components it includes and its layout
- to settings for the model, or for specific components.
When you save the settings, also remember to save the model.
There are two ways to save settings. In the settings tab, use one of the toolbar icons:
- Click
Save to save your changes.
When you save the settings, also remember to save the model. At the top of the modelling pane is a toolbar. Click the Save to save the model.
Create and open a new model
In the repository browser, expand Full Repository, then Analysis Models.
- To create a new model, right-click on Analysis Models and select Error rendering macro 'excerpt-include' : No link could be created for '_add_object'.Analysis Model.
PhixFlow displays a settings tab for a new analysis model. In Basic Settings, set:
Name:Introduction to Modelling- Click Save.
- In the settings tab toolbar, click Error rendering macro 'excerpt-include' : No link could be created for '_display_model'.. PhixFlow opens an empty model.
Add components to your model
The modelling pane is the white area on the left. You can have multiple files open in the modelling pane. When a model is open, PhixFlow displays the model name and its toolbar. Drag model components from the toolbar to add them to your model.
To drag a modelling component into your model:
- Click and hold the Error rendering macro 'excerpt-include' : No link could be created for '_add_stream_calculate'.icon.
- Drag the icon onto the modelling pane.
- Then drop the icon.
To move any component icon in a model, simply click, drag, then drop the icon in a new location.
When you have multiple components in your model, you can also use the layout tools to arrange them: 
Change component settings
When you drop a component into the model, on the right PhixFlow opens a settings tab.
- In the stream settings → Basic Settings, set:
Name:Practice Stream - Click
OK to save and close the settings tab. - PhixFlow updates the stream icon in your model to display the name
Practice Stream. - Now save your model. Click Save in the modelling pane toolbar.
Undo a change to a model
Sometimes you may make a change to a model that you do not want to keep. To reverse a change
- In your model, drag the stream to a different location.
- Without saving, click
Refresh. - You will see the model return to its previously saved layout.
