[gmx-users] Bilayer curvature

Dear All,

I have set two bilayers:
1. 400 DOPC
2. 320DOPC and 80 Cardiolipin

Second one show significant curvature during NPT equilibrium and MD run
(not in NVT eq.). Is it normal?

For the first bilayer, after adding the protein to the system, here also I
can see big curvature in the membrane.
Does anybody knows is it normal or something is wrong?
Which factors do affect the membrane curvature (like: initial conf., water,
ions, box size, equilibration steps, ...)?
