[Wien] Surface simulation

[MoonfalL]

Dear Mark :
        Can you tell you how to estimate whether the atom layers  is enough
for surface simulation?
        for example; two system : enough vacuum
                         A : m layers atoms
                         B : n layers atoms
          all other parameters (RMT,RKM,k-point ....) are same, after
caculation, how to judge which one is better?
       Thanks!
