Detailed Description

template<class LinkedCell, unsigned int dim>
class coupling::transferstrategies::DifferenceTransferStrategy< LinkedCell, dim >

from MD to macroscopic solver: mass and momentum are computed at the current timestep and mapped to macroscopic solver. The values are averaged over a certain time. from macroscopic solver to MD: The difference in mass and momentum between both solvers is computed and introduced on MD side.

Author: Philipp Neumann

Template Parameters

LinkedCell	the LinkedCell class is given by the implementation of linked cells in the molecular dynamics simulation
dim	refers to the spacial dimension of the simulation, can be 1, 2, or 3
