Here is the link to GROMACS 4.5.5, installed on the HorseShoe 6
I suggest you to start with something very simple, such as small
liquid water system. Here it is:
The faster you start with *real systems*, the more meaningful your
research project will seem to you. For instance, try to calculate
radial distribution functions (g_rdf utility in gromacs), diffusion
constant (g_msd utility), density (g_energy utility), viscosity
(g_energy), vaporization enthalpy, etc.
Change temperature (grompp.mdp file), change pressure (grompp.mdp
file) and recalculate the properties.
Change parameters (topol.top file), e.g. H-O-H angle and find our how
this *unreal new water* behaves.
Change the number of molecules (conf.gro) per unit cell and the shape
the box, and observe how this influences water's properties.
