Galerkin function
In mathematics, in the area of numerical analysis, Galerkin methods are named after the Soviet mathematician Boris Galerkin. They convert a continuous operator problem, such as a differential equation, commonly in a weak formulation, to a discrete problem by applying linear constraints determined by … See more We first introduce and illustrate the Galerkin method as being applied to a system of linear equations $${\displaystyle A\mathbf {x} =\mathbf {b} }$$ with the following symmetric and positive definite matrix See more Here, we will restrict ourselves to symmetric bilinear forms, that is $${\displaystyle a(u,v)=a(v,u).}$$ While this is not … See more The approach is usually credited to Boris Galerkin. The method was explained to the Western reader by Hencky and Duncan among others. Its convergence was studied by Mikhlin and Leipholz Its coincidence with Fourier method was illustrated by See more Weak formulation of a linear equation Let us introduce Galerkin's method with an abstract problem posed as a weak formulation on a Hilbert space $${\displaystyle V}$$, … See more I.

However, unlike the Collocation Method , it is based on the integral of the residual over the domain of interest. The residual \( R\left( x \right) \) is weighted over the domain of interest by multiplying \( R\left( x \right) \) by …

Moreover, our results illustrate that three out of the five methods conserve local mass and produce similar flux approximations when conductivity alteration is included.
