Representação de superfície
Abstract in Portuguese
Este trabalho consiste em introduzir uma nova abordagem de representação de superfície no ambiente de simulação Freeflow2D. Consiste em usar Partição da Unidade Implícita para estimar da superfície a geometria, normais e curvatura. Procurando se valer das vantagens de métodos do tipo meshless (sem malha) conservando no entanto a malha Lagrangiana, no interesse de manter o fácil acesso de vizinhança, inserção e eliminação de pontos

Abstract in English
The objective of this work is to introduce a new approache of surface representation within the Freeflow system. It consists of using implicit functions by means of Partition of Unit Implicit to estimate surface geometry, normals and curvature. Aiming at the advantages of meshless methods of surface representation whilst keeping the Lagrangian mesh in order to preserve ease of access of geometric vicinity, particle insertion and removal
