Colloidal solutions posses a wide range of time and length scales, so that itis unfeasible to keep track of all of them within a single simulation. As aconsequence some form of coarse-graining must be applied. In this work we usethe Multi-Particle Collision Dynamics scheme. We describe a particularimplementation of no-slip boundary conditions upon a solid surface, capable ofproviding correct force s on the solid bypassing the calculation of thevelocity profile or the stre ss tensor in the fluid near the surface. As anapplication we measure the friction on a spherical particle, when it is placedin a bulk fluid and when it is confined in a slit. We show that theimplementation of the no-slip boundary conditions leads to an enhanced Ensko gfriction, which can be understood analytically. Because of the long-rangenature of hydrodynamic interactions, the Stokes friction obtained from thesimulations is sensitive of the simulation box size. We address this topic forthe slit geometry, showing that that the dependence on the system size differsvery much from what is expected in a 3D system, where periodic boundaryconditions are used in all directions.
