By the end of this chapter you will be able to:

Save models and modelling objects

When you are modelling data in PhixFlow, you will be making changes:

• to a model, the objects it includes and its layout.
• to settings for the model itself, or to settings for its objects. Use one of the toolbar icons at the top of the settings tab:
  
  •  Save to save your changes but keep the settings tab open.
  •  OK to save your changes and close the settings tab.

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  Add 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  Display.
   In the white area on the left, called the modelling pane, PhixFlow opens a new, empty model.

Add objects to your model

You can have multiple files open in the modelling pane. When a model is open, PhixFlow displays the model name and its toolbar. Drag modelling objects from the toolbar to add them to your model.

To drag a modelling object into your model:

1. Click and hold Calculate Stream.
2. Drag the stream onto the modelling pane.
3. Then drop the stream. 

To move any object in a model, simply click, drag, then drop the icon in a new location.

When you have multiple objects in your model, you can also use the layout tools to arrange them: 

Change object settings

When you drop an object 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 model 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. Notice that the model returns to its previously saved layout.
