The flag of the Soviet Union consisted of a plain red flag with a gold hammer crossed with a gold sickle placed beneath a gold-bordered red star. This symbol is in the upper left canton of the red flag. The colour red honours the red flag of the Paris Commune of 1871; the red star and the hammer and sickle are symbols of communism and socialism.
The extended finite element method (XFEM) is a numerical technique based on the generalized finite element method (GFEM) and the partition of unity method (PUM). It extends the classical finite element method by enriching the solution space for solutions to differential equations with discontinuous functions.
The flag of the Russian SFSR was a defacement of the flag of the USSR. The constitution stipulated: The state flag of the Russian Soviet Federative Socialist Republic (SFSR) presents itself as a red, rectangular sheet with a light-blue stripe at the pole extending all the width [read height] which constitutes one eighth length of the flag.
The finite element method (FEM) is a powerful technique originally developed for numerical solution of complex problems in structural mechanics, and it remains the method of choice for complex systems. In the FEM, the structural system is modeled by a set of appropriate finite elements interconnected at
In mathematics, in particular numerical analysis, the FETI method (finite element tearing and interconnect) is an iterative substructuring method for solving systems of linear equations from the finite element method for the solution of elliptic partial differential equations, in particular in computational mechanics [1] In each iteration, FETI requires the solution of a Neumann problem in ...
Gander and Wanner [24] showed how Ritz and Galerkin methods led to the modern finite element method. One hundred years of method's development was discussed by Repin. [25] Elishakoff, Kaplunov and Kaplunov [26] show that the Galerkin’s method was not developed by Ritz, contrary to the Timoshenko’s statements.

Numerical methods such as the finite difference method, finite-volume method, and finite element method were originally defined on meshes of data points. In such a mesh, each point has a fixed number of predefined neighbors, and this connectivity between neighbors can be used to define mathematical operators like the derivative .
