[gmx-users] Does gromacs simulate rotation correctly?

[Arthur Roberts]

Hi, all,

Just curious.  Does gromacs simulate rotation correctly?  From my  
observation, it would appear that every object in the simulation both  
small and large has a similar rotational correlation time, which is  
not reality.  I would expect water for example to have an extremely  
short rotational correlation time with respect to a protein.  I  
appreciate your input.

Best wishes,
