1. A new multilevel smoothing method for wavelet-based algebraic multigrid poisson problem solver
In contrast to the standard algebraic multigrid, the Wavelet-based Algebraic Multigrid method relies more strongly on the smoothing method because the coarse spaces are chosen a priori. So, it is very important to develop new smoother methods, especially for those cases where the classical Gauss-Seidel smoothing method does not give good results. This paper

2. Smoother study of wavelet based algebraic Multigrid. / Estudo de suavizadores para o método Multigrid algébrico baseado em wavelet.
Este trabalho consiste na análise do comportamento do método WAMG (Wavelet-Based Algebraic Multigrid), método numérico de resolução de sistemas de equações lineares desenvolvido no LMAG-Laboratório de Eletromagnetismo Aplicado, com relação a diversos suavizadores. O fato dos vetores que compõem os operadores matriciais Pronlongamento e Restriçã

3. Formulação P do metodo de elementos finitos em problemas de elasticidade linear e não-linear com malhas 3D e em metodos multigrid algebricos
The main purpose of this work is to develop and implement (in C++ language) the p-version of the Finite Element Method (FEM) applied to linear and non-linear structural elastic problems with 3D non-structured meshes. To achieve this goal, we conduct a previous study which compares some sets of triangular and tetrahedral hierarchical basis functions available

4. ANÁLISE DE DESEMPENHO DA TÉCNICA DE MULTIGRID EM PROBLEMAS DE FENÔMENOS DE TRANSPORTE / ANÁLISIS DEL DESEMPEÑO DE LA TÉCNICA MULTIGRID EN PROBLEMAS DE FENÓMENOS DE TRANSPORTE / PERFORMANCE ANALYSIS OF THE MULTIGRID TECHNIQUE FOR TRANSPORT PHENOMENA PROBLEMS
The numerical solution of fluid flows problems with heat transfer requires the solution of a set of coupled non- linear partial differencial equations. The major computational effort in solving these equations is due to the solution of the algebraic systems resultant from the discretization of the conservation equations. The convergence rate of iterative met
