Finite Element Method: Global Approach

This lecture covers the finite element method, focusing on the global approach. Topics include the choice of nodal form functions, physical characterization of unknowns, insertion of approximations in the weak form, and advantages over the Galerkin method. The instructor explains the index form of the system of equations, the shape of the solution obtained, and the dense boundary conditions. The lecture emphasizes the extensive systematization of the process and the use of piecewise continuous weak polynomials with compact support.
