[gmx-users] Reproducing Chain Tilt on DPPC gel phase with Martini FF

[César Ávila]

Dear all,
I would like to simulate a DPPC membrane in gel phase using Martini Force
Field. As stated on

"Simulation of gel phase formation and melting in lipid bilayers using a
coarse grained model", CPL 135 (2005) 223-244

the correct 30º angle chain tilt for DPPC might be reproduced by reducing
the acyl chain spheres volume by 10%.
 So far, I have tried changing sigma and epsilon for C1-C1 pair interaction
without success.

Best regards
Cesar Avila
