Abstract
A multiscale method that couples a meshless Stokes solver and a DSMC simulator is reported. The method is based on overlapped Schwarz alternating method with Dirichlet-Dirichlet type boundary conditions for domain decomposition and meshless interpolation between sub-domains. The overlap can be zero for the case of Stokes-DSMC coupling. Agreement between the coupled simulation and DSMC results is demonstrated and dependence of convergence of the coupled method on the overlap, particle weight and number of DSMC time steps between coupling iterations is investigated. It is shown that within the range of parameters studied, convergence does not depend on the length of overlap and is not effected by the increased noise in DSMC estimates. The number of time steps simulated in each DSMC iteration should be selected so that the total simulated time till convergence is close to the time constant of the DSMC subdomain.
