[gmx-users] Chloroform Density problem

[Surahit Chewle]

Dear Users,

I am trying to solvate small organic molecule (8 molecules) of 20 atoms
each =160 atoms in Chloroform using Genbox.

according to the box volume that is created by the editconf (truncated
octahedron of 6nm) that is 166.28 nm, it should have roughly 1200 molecules
of chloroform. (not corrected for 160 atoms that are already present in the
system)

after playing around with these numbers in bold and underlined in the
solvent PDB file, I reached to the right density, but the number of
molecules is way too much for the given volume.
can someone guide what is the correct way where I can have right density
and right amount of solvent molecules for the given sized box in the
system?
I also tried to add the solvent molecules without solute in the box, but
the density and number correlation is still out of the order in that case.
