Abstract :
An implementation of the algebraic multigrid method and its application for solving matrix equations arising from 3D FEM static analysis are addressed. The method, which is based on multigrid principles, is designed to solve such problems efficiently by using only the information contained in the matrix equation itself without any geometrical background. A number of numerical experiments have been conducted to study the complexity of the algorithm as well as its convergence behavior
