[gmx-users] Warning with L-BFGS minimization

[Jochen Hub]

Hi,

with l-bfgs minimzation, grompp always reports

WARNING 1 [file em.mdp, line unknown]:
  For efficient BFGS minimization, use switch/shift/pme instead of cut-off.

even if the mdp gives
; Method for doing electrostatics
coulombtype              = PME
rcoulomb_switch          = 0
rcoulomb                 = 1.

I could't find anything on that in the archive. Is that a known issue?

Cheers,
Jochen
