OK, now I understand.

You can give to genbox any solvent that you like, provided that each 
molecule consists of a single residue (the residue number is used to 
distinguish molecules).  In the gromacs distribution there are a couple 
of other solvents present. Look in share/gromacs/top directory of your 
installation (or roll your own).

Hi

I want to use a solvent with two types molecules (for example linear and
cyclic Glucose form).
How can I fill box with them?

I highly appreciate for advice given me!

Best Regards
Rasoul

You can use genbox with  mixed solvents.

You can use genbox with  mixed solvents.




There are even how-to's on the Gromacs site to accomplish this:
