Condiciones de contorno en el metodo de diferencias finitas con mallas irregulares

Abstract

En el método de diferencias finitas con mallas arbitrarias, las ecuaciones de dominio se aproximan a partir de invertir la matriz estrella para cada estación. Varios procedimientos han sido sugeridos e implementados en la literatura para tratar condiciones de contorno en este método, distinguiéndose entre: (a) las condiciones de contorno se discretizan directamente; (b) las ecuaciones de dominio se discretizan en el contorno, previa modificación de la matriz estrella; (c) en el contorno se discretizan las ecuaciones de contorno y de dominio. En el presente trabajo se discuten las posibilidades y limitaciones de cada procedimiento a partir de ejemplos simples de ecuaciones de segundo y cuarto orden.
