Abstract

método implementado por computador, método para verificar um desenho de um objeto, sistema de computador e programa de computador. um método implementado por computador, um sistema de computador (132) configurado para executar o método implementado por computador, um programa de computador compreendendo instruções que, quando o programa é executado por um computador ou sistema de computador (132), fazem com que o computador ou sistema de computador (132) realize o método e um banco de dados (128) para uso no método são divulgados. o método implementado por computador para simular um processo de preenchimento de uma cavidade de molde (112) em um processo de moldagem por injeção usando um material plástico, o método compreende: i) discretizar pelo menos uma parte da cavidade de molde (112) em uma pluralidade de células (116); ii) definir um ponto de injeção de cavidade (114); iii) determinar uma direção normal da superfície (124) perpendicular à superfície da cavidade mais próxima (125) para cada célula (116); iv) determinar um sistema de coordenadas de célula para cada célula (116), definido por - uma primeira direção principal (118) paralela a uma direção de fluxo (120), - uma terceira direção principal (122) paralela à direção normal (124), e - uma segunda direção principal (126) perpendicular à primeira (118) e terceira (122) direções principais; e v) determinar a direção do fluxo (120) de um fluxo de molde para cada célula (116).
