Detailed Description

template<class LinkedCell, unsigned int dim>
class coupling::cellmappings::NieVelocityImpositionMapping< LinkedCell, dim >

This class employs an acceleration based on velocity gradients (in time) using the forcing term of the molecules.

employs an acceleration based on velocity gradients (in time) using the forcing term of the molecules. We currently expect that valid force entries are provided in each molecule, that is all molecule-molecule interactions have previously been computed. The scheme follows the descriptions in the paper by Nie et al., J. Fluid. Mech. 500, 55-64, 2004. However, we only average over single grid cells (no averaging over one (periodic) dimension or similar tricks ;-) ).

Template Parameters

LinkedCell	cell type
