### 30.2.1. Viewing and Editing Data Imported from a Profile Data File

When you import data from a profile data file, a corresponding user function is created in the Outline view under Simulation > Expressions, Functions and Variables > User Functions. Right-click the user function and select Edit to view and edit the Basic Settings.

In the Basic Settings tab, the Value Fields interact with the Parameter List to control the variables associated with each field when profile data is used to create boundary conditions automatically (see Profile Boundary Conditions in the CFX-Solver Modeling Guide).

To change the variables associated with a field:

1. Select an element in the Value Fields list.

2. Click the drop-down arrow beside the Parameter List field and select (or Ctrl-select) the variables that you want to associate with the field that you specified in the previous step. If a variable that you want to select does not appear, click Multi-select from extended list to see all of the variables that are available.

If the imported profile data has three Cartesian spatial fields (i.e. x, y, and z), you can display the profile data in the viewer by editing the corresponding user function. To display the profile data in the viewer:

1. Select the Plot Options > Visibility check box.

2. Optionally select the Color by Profile Variable check box and select a Profile Variable.

3. Optionally select the Profile Vector check box to visualize vectors defined from the variables in the profile file. There are two types of vector quantities available for selection in the drop-down list:

   - Standard Vectors

     These vector quantities are automatically constructed from the variables in the profile file, wherever CFX-Pre is able to recognize the available variables as components of a vector quantity. You cannot modify the settings for these vectors.

   - User Defined

     This selection enables you to manually specify the vector components individually. You can specify the Vector Type as either `Cartesian` or `Cylindrical`. The Profile Variable drop-down boxes enable you to select any variable defined in the file for each component. Components must all have the same dimensions.

4. Optionally change the rendering options (such as the type and size of the symbol used to mark each profile data point) by doing one of the following:

   - Right-click the profile in the tree view and select Render > Properties.

   - Right-click the profile in the viewer and select Render > Properties.

You can also control the visibility of the profile data by the visibility check box in the tree view, and by the Hide command in the menu that appears when you right-click the profile in the viewer.
