- W2389210307 abstract "A reverse-time migration method namely finite element-finite difference method (FE-FDM) for two-dimensional wave equation was proposed. The wave equation was handled by the combination of the finite element method and finite difference method in spatial domain. By the use of the semi-discretization technique of finite element method in distance-coordinate, the original problem can be written as a coupled system of partial differential equations with lower dimensions, which continuously depends on time and depth-coordinate. The finite difference method was employed to solve these partial differential equations with lower dimensions. The concept and theory of this method were introduced. Two numerical calculation examples showed the excellent performance and potential of this method." @default.
