Abstract
In this paper the investigation of the efficiency multigrid method as a solution method for large system of algebraic equations that arise from ordinary finite element analysis is presented. The mathematical background for multigrid methods and some points regarding definition of restriction and prolongation matrices for multigrid finite element analysis based on nested meshes are also given. The convergence rate and computation speed od=f the V-cycle and W-cycle multigrid algorithms are discussed and compared with the ordinary ICCG method, A comparison of the computation speed between multigrid method and the ICCG method is also presentedm showing that the multigrid method is very promising as a fast and accurate solution method is very promising as a fast and accurate solution method for large systems of equations or as a solution method for adaptive finite element computations.
