Introduction to Finite Element

Once we have a weak formulation from a strong formulation, “you just have to” calculate the solution! The finite element method is one of the numerical tools developed to calculate an approximate solution (see [1]). The finite element method proposes to set up, on the basis of weak formulations, a discrete algorithm (discretization) making it possible to search for an approximate solution of a partial differential problem on a compact field with conditions at the edges and/or in inside the compact.
