Development of a coarse mesh code for the solution of two group static diffusion problems
Description
This new coarse mesh code designed for the solution of 2 and 3 dimensional static diffusion problems, is based on an alternating direction method which consists in the solution of one dimensional problem along each coordinate direction with leakage terms for the remaining directions estimated from previous interactions. Four versions of this code have been developed: AD21 - 2D - 1/4, AD21 - 2D - 4/4, AD21 - 3D - 1/4 and AD21 - 3D - 4/4; these versions have been designed for 2 and 3 dimensional problems with or without 1/4 symmetry.

Este codigo de malha grossa para solucao de problemas de difusao estatica a duas ou tres dimensoes e dois grupos de energia se fundamenta no metodo de direcoes alternadas que consiste na solucao, alternadamente em cada direcao, de equacoes de difusao unidimensionais, com termos de fuga nas demais direcoes avaliados a partir de solucoes anteriores. Foram desenvolvidas, neste trabalho, quatro versoes para este codigo: AD21 - 2D - 1/4, AD21 - 2D - 4/4, AD21 - 3D - 1/4 e AD21 - 3D - 4/4, aplicaveis a problemas bi- e tridimensionais com ou sem 1/4 de simetria material.
