Go to the graphical search field (see image below).

Click "Workspace" as shown in image one or two below. By clicking "Workspace" you activate the workspace command. Activating the workspace command will redraw the graphical search field. In the graphical search field you will now see two tabs: one called "Summary" and one called "Table". When activating the workspace command you will automatically be placed on the "Table" tab in the graphical search field. Below the "Table" tab you will find a list of workspaces available in the model (see the third image below).
