 \item Transformation of the grid back to real space: An Inverse FFT is used to convert the reciprocal space potential back to the real space. 
 \item Force calculation: The force is given by the gradient of the potential.
-PME, SPME and P3M use different methods for calculating the force given the resulting potential.
