Uma estratégia de refinamento auto-adaptativo versão h do método dos elementos finitos aplicada a problemas bi-dimensionais regidos pela equação de campo
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.
