[gmx-users] Problem with constrains and degrees of freedom

[Sergi Ruiz Barragán]

I want to reproduce the simulations done by Luis et al in 
10.1021/acsnano.7b06805 , where they use a rigid graphene layers. I'm 
using constraints to keep the graphene sheet in a plane. However, I'm 
not sure if the degree of freedom are ok. In fact, I don't know where to 
check how many degrees of freedom are gromacs considering. In this case, 
when the graphene is simulated as a rigid lamina , it has a unique 
degree of freedom (up/down in the axis perpendicular to the sheet). 
However, I think this is not taking care by gromacs.
