– nonbondedFreq: how often to calculate the pairwise interactions;
AKA interactions within cutoff
– fullElectFrequency: how often to employ the long range PME
electrostatic calculation; AKA interactions beyond cutoff
The frequencies you refer to below (1-2-4) are reasonable.

I am curious, I am trying to set nonbondedFreq and fullElectFrequency.
The manual says this:
– nonbondedFreq: speciﬁes in number of time steps how often
nonbonded interactions should be calculated. It is useful for
saving computational time.
– fullElectFrequency: speciﬁes in number of time steps how of-
ten full electrostatic interactions should be calculated.
what exactly is the difference between these two? Are the interactions
of atomic point charges included in the nonbonded interactions?
I mean, what all is calculated in non-bonded?
If I am running MD just to get a realistic solvent configuration, with
TIP3P waters, would nonbondedfreq =2 and fullelectfreq = 4 be
appropriate or should I make the calculations more frequent?
