[gmx-users] Non periodic boundary conditions

[Mehmet Suezen]

Dear Gromacs users/developers,

I`d like to simulated a system without periodic boundary conditions(PBC)
so called free clusters.
Does any body know whether gromacs can simulate non-PBC? If it can do
so, How would be the parallel performance
differs, in account of both coulombic and non-bonded interactions?

Many thanks,

Mehmet
