Abstract in Portuguese
geração numérica de malhas tomou-se uma importante ferramenta na obtenção de soluções numéricas de equações diferenciais parciais (EDPs), em domínios físicos com geometrias complexas. Esta dissertação apresenta o Sistema Iterativo de Geração de Malha (SIGEM). O SIGEM foi desenvolvido durante este trabalho e utiliza o método diferencial que emprega EDPs elípticas para a geração da malha. O SIGEM permite a geração de malha em domínios simplesmente conexos bidimensionais, com o controle do posicionamento dos pontos pelo usuário. Para mostrar uma aplicação típica do SIGEM, foram geradas malhas em domínios irregulares, onde foram resolvidas a equação de Laplace e a equação do calor.

Abstract in English
Numerical grid generation has become an important tool in the determination of numerical solutions of pardal differential equations (PDEs) on physical domains with complex geometries. This work presents the Iterative System of Grid Generation (SIGEM). It generates grids by the partial differential equations method using elliptics PDEs. It allows the generation of grids on simply connected, two-dimensional domains. The user can control the position of individual points using appropriate forcing functions as source terms of the PDEs . To show a typical aplication of SIGEM, grids were generated on complex physical domains, followed by solution of the Laplace and the heat equations.
