Create a sub-directory for the tutorial called control_valve. Copy the control_valve.stl file (which contains the surface geometry) into the working directory. The file is supplied as part of the documentation download with release versions of STAR-CCM+ and can normally be found in the /doc/tutorials/controlValve directory.
Launch STAR-CCM+ and start a new simulation as normal. Select File>Import Surface.... The Open dialog will appear. Use the navigation tools in the dialog to locate the working directory select the control_valve.stl file from the list box, then press the Open button.

The other options in the panel can be left as default.
The output window will show a summary of the progress made. A total of 5570 faces and 2787 vertices will be imported. An Import representation node will also be added to the Representations node. Click on the Representations>Import node to see the properties of the surface.
