Dear gmx users and martini experts,
I would like to simulate a membrane system with two walls using a coarse-grained model using gromacs v.5.1. I receive the core dumping faults. I used related mdp options as follows
nwall = 2 ; wall at z=0 and z=z-box
wall-type = 12-6 ; direct 12-6 LJ as fn of distance from wall
wall-atomtype = C1 C1
wall-density = 120 120
wall-r-linpot = 0 0
ewald-geometry = 3dc ; Only Ewald sum compatible with slab geometry,$
wall-ewald-zfac = 3
comm-mode = none
refcoord_scaling = all
Pcoupl = berendsen
Pcoupltype = semiisotropic
tau_p = 5.0
compressibility = 3e-4 0
ref_p = 1.0 1.0
Please suggest me some options such as wall-atomtype, density etc.
