A Meshless Method for the Acoustic Wave Propagation with the Weighted Least Squares Filtering
Original language description
Meshless methods based on the collocation of hyperbolic equations are commonly stabilized using upwind approximation of the derivatives. This approach leads to stabilization of the numerical scheme, but its accuracy is significantly reduced by dissipation. For linear systems, however, high order of accuracy can be achieved by using central-type schemes and the stability of the numerical method can be ensured via filtering of the numerical solution. We present a simulation of the acoustic wave propagation phenomenon using meshless method that solves the Linearized Euler equations with the Weighted least squares filtering.
