Justin,


Indeed GenBox added insufficien of the SOL to my system due to the ussage of increased vdvdat ( I've used 0.350 value for the c atoms only but the were alot of void beetwen water and bilayer )

lipid_posres in Z directions have prevented the displacement of the bilayer but the water were distruibuted irregular on the bilayer surface at the end of NVT phase

By the way in Gmembed system I have no such problems because the were no need to use genbox but during processing of the system I've obtain warning

WARNING 1 [file membed.mdp]:
  Can not exclude the lattice Coulomb energy between energy groups



What does it mean?

grompp is warning you that it is impossible to exclude long-range (reciprocal space) interactions calculated with PME. Whatever you're trying to exclude cannot be completely excluded.


By the way could I indicate Area per lipid during processing of my system with the G_membed?


I don't know what you're asking here. g_membed has no need of APL information; it grows the protein into the membrane, a process that removes lipids but does not attempt to converge APL data in any way.
