Dear users,

I have a question about vdwtype. My question is if I use vdwtype=shift 
in nvt.mdp file:


; Neighborsearching
ns_type = grid ; search neighboring grid cels
nstlist = 5 ; 10 fs
rlist = 1.0 ; short-range neighborlist cutoff (in nm)
rcoulomb = 1.0   ; short-range electrostatic cutoff (in nm)
; Method for doing Van der Waals
vdwtype = shift
; cut-off lengths   
rvdw-switch  = 0

rvdw = 0.9,

I have this error:
Fatal error:
With dispersion correction rvdw-switch can not be zero for vdw-type = 
Shift


That I don't know how can I solve this problem.

Thank you

Errr... Setting rvdw-switch to a non-zero value might be worth trying.
