摘要：
This article deals with analysis of boudary conditions for meshfree Smoothed particle hydrodynamics method (SPH). Two variants of boundary condition were analyzed, Dynamic boundary condition (DBC) and Boundary integral (BI), on one simple case. Furthermore we introduce a possible shape of an additional term for BI formulation, which models the tangential interaction of the fluid with boundary. A comparison between BI with additional term and DBC is made using the example of horizontal motion of fluid particle over an infinite wall.
