　　The Finite Particle Method(FPM)is a typical meshfree particle method,which is developed on the basis of standard smooth particle hydrodynamics(SPH)method.In FPM,a function and its derivatives are obtained simultaneously.The method can produce better accuracy near boundaries where particles support domain is incomplete.
