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 itself, or to settings for its components. Use one of the toolbar icons at the top of the settings tab:
  
  • Click  Save to save your changes.
  •  OK

Create and open a new model

1. In the repository browser, expand Full Repository, then Analysis Models.
   

    How?

   

2. 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.

3. PhixFlow displays a settings tab for a new analysis model. In Basic Settings, set:
   Name: Introduction to Modelling

4. Click  Save.
5. In the settings tab toolbar, click 
   Error rendering macro 'excerpt-include' : No link could be created for '_display_model'.
   .
   In the modelling pane, PhixFlow opens a new, 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:

1. Click and hold
   Error rendering macro 'excerpt-include' : No link could be created for '_add_stream_calculate'.
   .
2. Drag the stream onto the modelling pane.
3. Then drop the stream. 

To move any component 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.

1. In the stream settings → Basic Settings, set:
   Name: Practice Stream
2. Click  OK to save and close the settings tab.
3. PhixFlow updates the stream icon in your model to display the name Practice Stream.
4. 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.

1. In your model, drag the stream to a different location.
2. Without saving, click  Refresh.
3. You will see that the model returns to its previously saved layout.
