Meshfree methods for computational fluid dynamics

Abstract: Abstract. The paper deals with the convergence problem of the SPH (Smoothed Particle Hydrodynamics) meshfree method for the solution of fluid dynamics tasks. In the introductory part, fundamental aspects of meshfree methods, their definition, computational approaches and classification are discussed. In the following part, the methods of local integral representation, where SPH belongs are analyzed and specifically the method RKPM (Reproducing Kernel Particle Method) is described. In the contribution, also the… Show more

“…However, it should be noted that the SPH also presents some lack of conservation (typically mass) which leads to accuracy problems in particular applications. As shown in (Niedoba, Čermák & Jícha, 2013) significant improvements can be achieved by applying particular settings of the simulation parameters and specific treatment of boundary conditions, but this causes dependency on the problem and userspecified parameters.…”
