I want to analyze my MD trajectory for system which I
obtained with Ewald by decomposition of all my forces in system which I have. Particular, I want to find only unbounded forces (coulomb and vdW) between charge membrane and charge protein. All solvent and counterions I have switched off. For that case we should have interaction
between charged particle near infinitely large surface
from classic point of view, but results are not coincidence
qualitatively and quantitatively.

Thanks, Victor
