TL;DR: In this article, a hybrid smoothed finite element method (HS-FEM) using triangular elements is presented for the two-dimensional underwater acoustic scattering problems, which can provide a close-to-exact stiffness of the continuous system, thus the numerical dispersion error can be significantly decreased.

TL;DR: In this paper, the smoothed finite element method using four-node quadrilateral elements (SFEM-Q4) is employed to resolve underwater acoustic radiation problems, which can be regarded as a com...

TL;DR: In this paper, the gradient field of the problem is smoothed using gradient smoothing operations over the edge-based and face-based smoothing domains in two-dimensional plate and three-dimensional fluid, respectively.

TL;DR: In this paper, a radial point interpolation method (RPIM) was used to improve the accuracy of the standard finite element (FE) solutions for acoustic radiation computation. But this method is not suitable for the use of a single antenna.

TL;DR: The results of several numerical examples have shown that with same group of field nodes the present methodology can lead to much more accurate solutions than finite element approach, in particular for relatively high frequencies, and can also generate comparable solutions in comparison to other global Galerkin meshfree techniques.
