| Outline of Final Research Achievements |
In this study, we developed a full-waveform inversion using a mesh-free finite-difference method for accurate and efficient calculation. In the mesh-free finite-difference method, it is easy to simulate full-wavefield in an effective manner with adaptive mesh refinement which corresponds to an inverted velocity structure.
We investigated the effectiveness of the proposed method using numerical experiments. By comparing with the conventional finite-difference method, it is indicated that we can invert high accuracy velocity structures with considerable reduction of computational costs.
