Pair_style meam/c

Hi Bahman,

a more recent version of Lammps would give a more descriptive error message, but:

In pair_coeff commands I inserted below parameters required for simulation of Mg according to this paper(Modelling Simul. Mater. Sci. Eng. 23 (2015) 015004 (19pp)):

re = 3.19
Cmin = 0.49
Cmax = 2.90

Please compare the precise syntax to that given in the documentation. In particular, you're missing the element indices of what these quantities apply to.
