【Abstract】 This paper presents a contour line generation parallel method based on quadratic isoparametric element. In this method, the whole area is divided into many quadratic isoparametric elements by means of finite element method. The contour line in each isoparametric element is generated in parallel, and the whole contour is assembled. The result shows that this method improves the computation efficiency under the condition that the precision can be guaranteed.更多还原
