Detailed Description

template<typename T, typename DESCRIPTOR, int NORMAL_X, int NORMAL_Y, int NORMAL_Z>
class olb::FreeEnergyWallProcessor3D< T, DESCRIPTOR, NORMAL_X, NORMAL_Y, NORMAL_Z >

PostProcessor for the wetting boundary condition in the free energy model.

This is required to set rho on the boundary (using the denisty of the neighbouring cell in direction of inwards facing normal at the boundary), as the coupling between the lattices requires the calculation of a density gradient.
