It has been shown that Galerkin spatial discretization combined with Crank-Nicolson temporal discretization of the advection equation of level set yields a good result and that consistent streamline upwind Petrov-Galerkin(CSUPG) discretization of the redistancing equation gives satisfactory solutions for two test problems while the solutions of streamline upwind Petrov-Galerkin(SUPG) discretization are dissipated by the numerical diffusion added for the stability of a hyperbolic system. Furthermore, it has been found that the solutions obtained by CSUPG method are comparable to those by second order ENO method. 대한기계학회 Level Set Redistancing 알고리즘의 유한요소 이산화 기법에 대한 연구 Study on the Finite Element Discretization of the Level Set Redistancing Algorithm Article 2 대한기계학회논문집 B, v.29, no.6, pp.703 - 710 대한기계학회논문집 B 29 6 703 710 kci ART001093923 Finite Element Method Level Set Method Redistancing Algorithm Streamline Upwind Petrov-Galerkin 유한요소법 Level Set 방법 Redistancing 알고리즘 유선상류 유한요소
