TL;DR: In this paper, a stable node-based smoothed finite element method (SNS-FEM) is proposed for analyzing acoustic problems using linear triangular and tetrahedral elements that can be generated automatically for any complicated configurations.

TL;DR: The method provides a new implementation of the conventional distance transformation technique to make the result stable and accurate no matter where the projection point is located to compute nearly singular integrals arising in the boundary integral equations (BIEs).

TL;DR: In this article, a stable nodal integration method with strain gradient (SNIM-SG) is proposed for dynamic problems using linear triangular and tetrahedron element, except for considering the smoothed strain into the calculation of potential energy functional as NS-FEM.

TL;DR: An improved finite element method for solving acoustic problems by re-distributing the mass in the mass matrix to "tune" the balance, aiming to minimize the dispersion errors.

TL;DR: A cell-based smoothed radial point interpolation method (CS-RPIM) based on the generalized gradient smoothing operation is proposed for static and free vibration analysis of solids.
