摘要: A second order interface anchoring method has been developed and used with fast sweeping algorithm for reinitialization of a level set function. The algebraic formulation ensures that the location actual is preserved, leading to better mass conservation property. It also provides high accurate constraint solving Eikonal equation on finite difference grid. Geometric properties such as surface normal curvature are subsequently computed from reinitialized distance Various analytical functions modeling distortion in field considered accuracy evaluated using first schemes. shown computation requires anchor addition method. Mass property analyzed by considering test problems literature including classic Rider–Kothe single vortex problem. suitable efficient parallelization both distributed memory on-node shared parallel systems. Scalability performance scheme multiple architectures demonstrated.
