Now optimize the geometry using ADF, as in the second tutorial:
Enter a title (like 'Ethane')
Select the 'Geometry Optimization' preset
Select File → Run
Save your input with a nice name ('ethane')
Wait for the calculation to finish (check the logfile)
In the dialog that appears, click Yes to import the optimized geometry
Note that the molecule might be rotated by ADF to fulfill the symmetry requirements of ADF.
