You can use the Options dialog to display any of the toolbars that exist in STAR-CCM+. It is also possible to display toolbars with the menu or the right-mouse click.
Select Tools > Options. This activates the Options dialog.
Open the IDE Configuration node in the Options node. Open the Toolbars node inside the Look and Feel node, and then select the node of the individual toolbar. The Visible property in the right-hand portion of the dialog contains a checkbox. Tick that checkbox to include the toolbar in the STAR-CCM+ workspace.
Click Close.
