Select the bottom row in the table and click the Open button () in the toolbar. You can also double-click the row. Select No if you are asked to save any unsaved changes.
The first version is opened in the COMSOL Desktop. There is no Import () node under the Geometry 1 () node, and the Description field is empty.

Select the middle row in the table and click Open ().
The second version is opened in the COMSOL Desktop — the import node is now present under the geometry node, but the Description field is still empty.
