[gmx-users] fudgeLJ and fudgeQQ setting in the *.itp file

Hi All,

I was just wondering whether someone knows what are the considerations in
choosing the values for* fudgeLJ* and *fudgeQQ* in the [defaults] section of
the *.itp file. (these  two  factors multiply the 1-4 LJ interactions and
the electrostatic interactions , respectively)

the manual doesn't say much but using defaults of 1.0, but I wanted to know
whether one should change those and if so, on what cases?

Many Thanks,
