WebNov 10, 2015 · An efficient implementation of a high-order finite element method for the Helmholtz equation was presented. It is designed to tackle realistic acoustic engineering problems, typically large-scale 3D models to be solved over a large number of frequencies. The key aspect of this approach can be summarized as follows. WebWe use finite elements methods to solve Equations ( 2) and ( 5 ), and work with a continous Galerkin formulation. As mentioned above, this can be done by smoothing the discontinuities of the fluid parameters (e.g., the fluid density and viscosity) at the interfaces using the regularized Dirac and Heaviside functions Equations ( 7) and ( 8 ). chipseeker peak annotation
