elastic constants for lipid bilayer

Please reply to the mailing list, not to me – thanks.

You must be using an old LAMMPS version. Please update to the current version and try again.

From lj/sdk/coul/long doc page, “Style lj/sdk/coul/long computes the adds Coulombic interactions with an additional damping factor applied so it can be used in conjunction with the kspace_style command and its ewald or pppm or pppm/cg option.”.
