Operator-splitting based fast sweeping methods for isotropic wave propagation in a moving fluid (English)
0 references
The authors develop various operator-splitting based fast sweeping methods for solving an anisotropic eikonal equation arising in isotropic wave propagation in a moving fluid. The main idea used is that this anisotropic eikonal equation is defined by a sum of two first-order differential operators. These operator-splitting methods rely on the Peaceman-Rachford scheme, the Douglas-Rachford scheme, the \(\theta\)-scheme, and the regularized \(\theta\)-scheme. Several numerical examples are presented to demonstrate that some of the proposed algorithms are effective.
