[gmx-users] Simulation of charged systems (2)

[Felipe Pineda, PhD]

Hi again!

many thanks to Xavier for his response, the only one I got so far ... I 
had the same impression, but I'm seeking for theoretically/technically 
more funded statements. My impression is also that there are different 
kind of "equations" depending of the treatment of long-range 
electrostatic interactions.

My concrete question is now: are net charge corrections to the Ewald 
potential implemented in Gromacs?

Thank you and kind regards,

Felipe
