Original abstract

In this paper we present an accuracy improvement of the meshfree Finite point method. This high-order method has been used to solve the sound propagation problems, which can be modelled by linearized Euler equations. High accuracy has been obtained using polynomial reconstruction of variables involved in the Riemann solver. The order of the meshfree method will be verified on 2D acoustic pulse problem which serves as a benchmark problem with known analytical solution.

Czech abstract

Je prezentováno zpřesnění bezsíťové metody Finite Point. Tato metoda vysokého řádu byla používána k řešení šíření zvuku modelováním linearizovaných Eulerových rovnic. Vysoká přesnost byla získána použitím polynomiální rekonstrukce proměnných v Riemannově řešiči. Řád bezsíťové metody je verifikován na 2D akustickém pulsu, který slouží jako benchmark se známým analytickým řešením.
