A method of obtaining (numerically) approximate solutions to (usually) differential equations. It consists of a method of discretization splitting the domain into disjoint subdomains over each of which the problem has a simpler (approximate) solution, and a method of reassembling those pieces to obtain a solution over the whole domain.

If there is a refrence to show differences between meshes, please let me know. $\endgroup$ – Rosa Jan 29 '16 at The finite element method (FEM), or finite element analysis (FEA), is a computational technique used to obtain approximate solutions of boundary value problems in engineering.
Boundary value problems are also called field problems. The field is the domain of interest. The finite element procedure consists in finding an approximate solution in the form of piecewise linear functions, piecewise quadratic, etc.
For two-dimensional problems, one of the most frequently used approaches is to triangulate the domain and find the approximate solution which is Cited by: Jul 14, · It is proven that the condition number of the linear system representing a finite element discretization of an elliptic boundary value problem does not degrade significantly as the mesh is refined locally, provided the mesh remains nondegenerate and a natural scaling of the basis functions is allesfuersjagen.com by: Finite element results by different meshes.
Ask Question Asked I am so new in finite element and these days just try to undrestand fem better but it sounds like you should be reading an introductory finite element method book in order to get a better handle on the basic method before delving into the details of which mesh.
Structured mesh quality optimization methods are extended to optimization of unstructured triangular, quadrilateral, and mixed finite element meshes. N"ew interpretations of well-known nodally-bssed objective functions are made possible using matrices and matrix norms.
The matrix perspective also suggests several new objective functions. FESOM (Finite-Element/volumE Sea ice-Ocean Model) is a multi-resolution ocean general circulation model that solves the equations of motion describing the ocean and sea ice using finite-element and finite-volume methods on unstructured computational grids.
The model is developed and supported by researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI Developer(s): AWI.

This paper describes a control-volume, finite-element technique for coupling coarse grids with local fine meshes. The pressure is treated in a finite-element manner, while the mobility terms are upstream weighted in the usual way.
This requires identification of the cell volume and edges that are. Polygonal finite elements displaying linear displacement on specified edges and quadratic displacement elsewhere are formed.
