Detailed Description

Class FastSweepingLSMethod provides a fast-sweeping algorithm implementation of the level set method. Specifically, this class produces a solution to the Eikonal equation $|\nabla Q | = 1$ , which produces the signed distance away from an interface.

Note: The class can also compute distance function from physical domain boundary if specified through input file. In presence of a physical domain wall, the distance function at a grid point is D = min(distance from interface, distance from wall location).
