Dear gmx friends,
Is there the best water model for each force fields? Which options are supposed
to be noticed in applying the best water model.
I need to tell you that I apply C36 in my simulations.
Thanks in advance.
Sincerely,
Shima

For CHARMM the typical water model is TIP3P, although I tend to use TIPS3P
since it's been reported on the mailing list to give better interactions with
bilayers. (Also easier to pass by picky reviewers at the expense of ns/day,
obviously).
The following thread may be helpful too:
Hi,
pdb2gmx -f 1LYD.pdb -water tip3p
Why is -water tip3p command ( tip3p water model) used? What the purpose?
Afterwards, genbox command is already added to solvent water as the
following:
genbox -cp box.gro -cs spc216.gro -p topol.top -o solvated.gro
Thanks

This chooses the water model embedded in the system topology written by
pdb2gmx.
Afterwards, genbox command is already added to

HI
The thing is the definition of atom type, OW and H in gromos 96 are
different from tip3p.itp, OWT3, HW.
same thing as other tip*p.itp.
How to fix this?
Thank you

Hi
Can the TIP3P water model used under gromos 96 force field?
Although the Amber_TIP3P.top can port to gromacs, it based on the
amber99 force field. I read about the imcompatibility of any two force
field parameters from different sources, such as amber99 and gromos96.
Is Gromacs only limited

Hi
Water model = amber port to gromacs
The two steps are shown on the archive.
1. #include ffamber_tip*pin the .top file
2. include an #ifdef_FF_AMBER statement in tip*p.itp

them first to see that

Should I also #include ffamber99.tip in the .top file?
