WebYou'll need to be careful to ensure your calculated stress is corrected for the finite basis set (i.e. that you've removed the Pulay Stress terms), for example using the method of Francis & Payne[1]. If you don't do that you'll have to make the cut-off energy extremely high to get reasonable results.
