A generalized front marching algorithm for the solution of the eikonal equation.
The purpose of this paper is to study a new front marching algorithm towards solving the eikonal equation. The algorithm can be used on nodes that are located on highly distorted grids or on nodes that are randomly located. The accuracy of the method depends on the principle curvature of the wave front solution. Extensive numerical experiments are presented (for a variety of node configurations, shadow, nonconvex and nondifferentiable solutions).
