Subject: lipid bilayer separation

Dear all,


I have a simple lipid bilayer system, POPC in water built up with charmm GUI.
Now I just want to add more water on each side of the lipid, as shown in the attachment.
However, when I energy minimize and equilibrate it, the bilayer split up.
Any guess on the reason?

Many thanks,

Yao
