walberla::pe_coupling::discrete_particle_methods::LubricationForceEvaluator Class Reference

Detailed Description

Evaluates the lubrication force between for a sphere-sphere or a sphere-plane pair.

The force is calculated as given in: R. Ball, J. Melrose, A simulation technique for many spheres in quasi–static motion under frame–invariant pair drag and Brownian forces, Physica A: Statistical Mechanics and its Applications 247 (1) (1997) 444–472. doi:10.1016/S0378-4371(97)00412-3.

However, currently only the normal component is included.

These formulas contain more components than the version from "pe_coupling/utility/LubricationCorrection.h"

#include <LubricationForceEvaluator.h>
