This study aims to develop a tsunami numerical model which is capable to include several grid systems and facilitate the process of assembling domains of different resolutions. The assembly of structured domains (inner and outer) is achieved by constructing an intermediate unstructured grid between them. The present scheme is able to diminish short period waves reflected on the boundary of a coarse grid domain. A numerical simulation consisting of a Gaussian-hump shape is used for validation by determining the energy transferred/retained in a finer grid domain. In addition a practical application, the 2010 Chilean Tsunami, is provided as a case study to confirm the validity of proposed model.
