What is GLS Finite Element Method for Helmholtz about?

This document summarizes a research paper that develops a Galerkin least squares (GLS) finite element method for solving the two-dimensional Helmholtz equation. The GLS method introduces a local mesh parameter that can provide accurate solutions on coarser meshes compared to standard Galerkin methods. Through two-dimensional Fourier analysis, optimal GLS mesh parameters are derived that reduce phase error for wave propagation in any direction over an element. Several numerical examples are presented to comp
