Hi, No. Models without cutoffs will scale badly with particle count. Adding cutoffs is not always a performance win either, because while that saves computation of interactions, it adds the need to periodically search for which particle interactions to compute. Mark On Sat., 9 Feb. 2019, 17:24 N

[gmx-users] PBC conditions for Vacuum simulation

2019-02-09 Thread Neena Susan Eappen
Hello gromacs users, I am trying to model a peptide in gas phase which requires proper conditions like: no PBC, no cut-offs for VanderWaals and electrostatics, coulomb type not PME. However, this increases computational time by N^2 for N number of atoms. Is there a way to mitigate this? Many t
