We develop a fast method to localize the level set method of Osher and Sethian (1988, J. Comput. Phys. 79, 12) and address two important issues that are intrinsic to the level set method: (a) how to extend a quantity that is given only on the interface to a neighborhood of the interface; (b) how to

โฆ Synopsis
A method is introduced to decrease the computational labor of the standard level set method for propagating interfaces. The fast approach uses only points close to the curve at every time step. We describe this new algorithm and compare its efficiency and accuracy with the standard level set approach. 1995 Academic Press, Inc.

General moving-interface problems are solved by a new approach: evaluating an explicit semi-Lagrangian advection formula with efficient geometric algorithms and extracting the moving interface with a fast new contouring technique. The new approach decouples spatial and temporal resolutions, and grid
A fast modular numerical method for solving general moving interface problems is presented. It simplifies code development by providing a black-box solver which moves a given interface one step with given normal velocity. The method combines an efficiently redistanced level set approach, a problem-i
## Abstract In this work, a reinitialization procedure oriented to regularize the level set (LS) function field is presented. In LS approximations for twoโfluid flow simulations, a scalar function indicates the presence of one or another phase and the interface between them. In general, the advecti

Modeling of microstructural evolution during thin-film deposition requires a knowledge of several key activation energies (surface diffusion, island edge atom diffusion, adatom migration over descending step edges, etc.). These and other parameters must be known as a function of crystal orientation.
