When running CASTEP calculations with the Tkatchenko-Scheffler method switched on (default settings), I get a warning:
WARNING: Your unit cell might be too small to get accurate results for van der Waals
Is that something to worry about? Unfortunately I cannot afford using a larger unit cell for my system.
