TI - A Geometrical Approach for Solving 2D Eikonal Equation T2 - Computer Modeling in Engineering \& Sciences PY - 2005 VL - 8 IS - 1 SN - 1526-1506 AB - Solving the Eikonal equation is popular due to its potential applications in various areas. Numerical method is the most common approach to solve the equation. This paper presents a geometric approach to solve the equation. Each point in a two dimensional domain with a given velocity field is characterized by the least time from the source. The path of least time is obtained by the Euler equations characterizing the extrema of the variation problem. A geometric representation of the space time function for the source is constructed. The solution to the eikonal equation is obtained based on space time geometry. KW - path of least time KW - eikonal equation KW - front propagation DO - 10.3970/cmes.2005.008.001
