Dear LAMMPS usrs.
Now I am using PPPM fortran version to calculate long-range Coulomb force.
In order to use PPPM, I should write accuracy(long_prec) and cutoff radius (cutcoul) for ‘coulomb style’ command in input script.
However, in C version, cutoff radius is suggested by program.
With fortran version, should user change the optimal value of cutoff radius depending on the system?
