Abstract

Este trabalho investiga a performance do esquema iterativo de inversão por blocos de um nodo, arquitetado com as equações discretizadas do método linear nodal. O método é aplicado a um problema de transporte de nêutrons, em meio nãomultiplicativo, a um grupo de energia, considerando-se espalhamento isotrópico. A modelagem matemática trata da migração dos nêutrons na formulação de ordenadas discretas, em geometria bidimensional e em sistemas de coordenadas Cartesianas. Resultados numéricos para o problema-modelo ilustram o desempenho computacional do método linear nodal no esquema iterativo de inversão por blocos.
