[gmx-users] flexible water vs. rigid water

[qiao rui]

Hi, Gromacs-er:

	I am curious whether the differnt water model can give different
dynamic properties, especially viscosity? In particular, which is better
in terms of providing good viscosity - flexible water or rigid water?

	In addition, what is the major advanges of using flexible water
rather than rigid water molecules? (rigid one is easier to implement,
right?)

	Is there a flexible SPC/E water model? If there is, how to include
it in the Gromacs simulation?

	Thanks a lot!

	sincerely,

	Rui
