The classic finite element method (FEM) is an effective numerical tool for the study of underwater acoustic propagation which is of great importance for the utilization of marine resources. However, the numerical solutions obtained by the FEM for the acoustic problems are unreliable at relatively high computational wavenumbers. In this work the overlapping finite element method (OFEM) is introduced to the time-harmonic acoustic propagation and an enriched scheme (EOFEM) augmented by the harmonic trigonometric functions is proposed to improve the performance of the original scheme. The performa...
