Abstract

This paper is devoted to the presentation of a control volume based finite element method (CVFEM). Its implementation is explicitedfor both Helmholtz and primitive variable formulations for planar and spatial problems. Application for solving acoustical eigenmode shows that the CVFEM is at least as accurate as the Galerkin FEM.
