Two important applied geometry problems are solved numerically. One is that of determining the nearest boundary distance from an arbitrary point in a domain. The other is that of determining (in a shortest-path metric) the distance between two points with the obstacles boundaries traversed inside the domain. These problems are solved by the time relaxation method as applied to a nonlinear Hamilton–Jacobi equation. Two major approaches are taken. In one approach, an equation with elliptic operators on the right-hand side is derived by changing the variables in the eikonal equation with viscous terms. In the other approach, first- and second-order monotone Godunov schemes are constructed taking into account the hyperbolicity of the nonlinear eikonal equation. One- and two-dimensional problems are solved to demonstrate the performance of the developed numerical algorithms and to examine their properties. Application problems are solved as examples.
