Abstract

acoustic equation is an important equation in order to determine wave propaganda in a medium.The Application of acoustic equation vastly known , i.e. elastic wave propagayion,fluid dynamics and gas dynamics equivalent. This paper present radial basis funtion-discontinuous garlenkin method (RBF-DGM)in order to solve acoustic equation. The RDF-DGM method is a numeric method, proposed to solve partial differential equiation (PDE). RDF-DGM approximated the space domain with RBF and using DGM for time integration method. RBF-DGM application presented then in order to solve acoustic equation. the numerical of RBF-DGM presented, and compared with analytical solution as a result. the numerical result, show thatn the RBF-DGM (linear) predicting the exact results or analytical well.
