Meshless finite element method
Web25 jul. 2003 · Furthermore, the method proposed also shares several of the advantages of the finite element method such as: (a) the simplicity of the shape functions in a large part of the domain; (b) C 0 continuity between elements, which allows the treatment of material discontinuities, and (c) ease of introduction of the boundary conditions. Web1 jan. 2024 · January 1, 2024. Mainstream finite element analysis (FEA) has a long tradition of using a discrete element-based approach. The elements define the structural domain, and their combined behavior describes the response. A range of methods described as “meshless” is emerging. This is a paradigm shift for the traditional analyst, …
