Dear all
I am new user to ATC package, I want to calculate J. integral for pre-cracked iron using eshelby stress. I follow same procedures as explained in (in.eshelby_stress) given in example directory. My question is,
when I read the initial configuration from data file I got this warning
ATC: WARNING: Cannot get number of atoms per cell from lattice
why I got such warning and does this warning affect my J.integral calculation?
Regards
Tamer
