hi everyone
I need to pull the two parallel monolayers together,the two monolayers are in
the x-y plane , so i pull the one along the z direction,but it stay still! i
tried several times ,but all failed!
i use the
[position_restraints ]
1 1 90000 90000 4000
2 1 90000 90000 4000
the 1 and ２ are the atoms in the long molecules that form the monolayers ,if i
decreased the fx,fy,fz,it show core fault and stopped!
the ; Force constants in kJ/(mol*nm^2)
afm_k1 = 100000
who can tell me why!
thanks !
