Description

Various types and variants of alternating direction methods. (ADM), were applied to the solution of the time-dependent heat conduction equation, with source, in regions with axial simmetry. Among the basic ADM's, the alternating direction explicit was the one which performed better. An exponential transformation coupled to the ADE seems to be the variant with greater potential, especially if used with a variable time step scheme. (Author)

Abstract (Portuguese)

Diversos tipos e variantes dos 'alternating direction methods', (ADM) foram aplicados a solucao da equacao de conducao de calor, com fonte, regime transitorio, em regioes axissimetricas. Os resultados obtidos, mostram as vantagens de algumas variantes em relacao no metodo tradicional de Crank-Nicolson. O 'alternating direction explicit', (ADE), foi entre os ADM basicos, o que mais se destacou. Entre todos, o ADE acoplado a uma transformacao exponencial parece ser a variante com maior potencial, principalmente, quando usada com intervalo de tempo variavel. (Autor)
