Hi,

Increase the number of layers and let all atoms to be relaxed... So you
will check "how deep" the relaxation of the atoms from surface will
influence the atoms of the bottom layers... With that test you will have
the correct slab tickness (which will be the half of the converged slab
found in the test) and number of layers to be relaxed in your simulations...
