An optimization of FIM method for three-dimensional eikonal equations
A Fast Iterative Method (FIM) for eikonal equations  are convenient and optimal in two-dimensional and small three-dimensional models. But it takes a lot of time and random access memory for big three-dimensional models. This article describes the time and memory optimization of this method for big 3d models. The results of simulations are presented
