Creating an Object List
Create an object list when you want to group multiple objects for convenient selection and processing. Creating an object list is a convenient way to identify and select a group of objects for a field plot or calculation. Objects in a list can still be treated as separate objects. The same object can be included in several different lists.
To create an object list:
- If you are selecting in the Modeler window, make sure that the modeler is in object selection mode by pressing the O shortcut key. This is not necessary for selecting in the History Tree.
- Select the objects you want to include in the list.
- Click Modeler> List> Create> Object List.
The object list is created with the default name Objectlistn. It appears in the History Tree under Lists. Selecting an object list displays the properties of that list in the docked Properties window. One of the properties is a list of objects contained in the list.
To rename the Object list, edit its Name in the docked Properties window. Object lists are sorted in alphanumeric order.
The object list is treated as one volume when you plot and perform fields calculations. It will be listed in the Geometry window of the Fields Calculator when you select Volume.
There is an automatically created list called AllObjects. Select this list selects all objects in the model. If a list contains mixed types of geometry, for example, volume and sheet objects, the volume calculation only uses the geometry of the highest dimension in plots or integral, and so forth.
- Line objects in the list do not affect where the fields are saved. If all objects in the list are lines, fields will be saved on all objects.
- To post processing on line object when saving fields on object/face list, include both the line and its containing object/face in the list.
Example: To plot the E-field on a surface formed by the intersection of the XY-plane and several objects, first define a list of these objects. Then, when plotting fields, select the object list name from the Geometry window of the Fields Calculator. Fields will be plotted only at the intersection of the plane and the objects in the list.
