[Pedro Alexandre Lapido Loureiro]

Hello,

After using the topol.top files of the DPPC benchmark, I was wondering:
1)what is the meaning of "#define FF_GROMACS" ?
2)the normal LJ interactions are not explicitly written in this top file, so the
program must calculate C(6)ij and C(12)ij (and the 1-4 interactions,also, as
long as generate pairs = yes).
Suppose I want to use such an extended topology file for my own system: will
this extra calculation deteriorate the performance of the program?

Cheers,

Pedro.
