In this work a self-adaptive refinement procedure (h-version) for the Finite Element Method (FEM) solution of two dimensional potential problems is studied. The mesh refinement strategy and the a-posteriori error analysis are also discussed. The Galerkin formulation for FEM is utilized and the resulting system of equations is solved by Preconditiohed Conjugate Gradients. Several problems are analysed and results compared with the available analytical and numerical solutions.Este trabalho tem como propósito o estudo da estratégia de refinamento auto-adaptativo versão h do Método dos Elementos Finitos (MEF) na análise de problemas bi-dimensionais lineares regidos pela equação de campo em regime permanente.
