Are you doing NPT remd?
What target pressure are you using?
What are the box dimensions?

> Dear All,
> I am running REMD simulations. have divided 100 ns into 5 jobs of 20 ns each.

> Possible solutions are to restart from a recent checkpoint,
> increase margin, or disable useFlexibleCell for liquid simulation.
> can some one please explain what this error technically means.
> i am already using margin of 1 A my water box is cubic with l=50 A
> in log file i get this value "PME GRID DIMENSIONS 54 54 54" why is this 54
> instead of 50.
> what effect will it have if
> 1. I restart job1 with margin as more than 1.
