A Tsunami Propagation Modeling Based on the Adaptive Mesh Refinement


Abstract eng:
We develop an automatic system for generating the optimal mesh model based on the adaptive mesh refinement method and the tsunami propagation simulation code adapted for the adaptive mesh model. The adaptive mesh is constructed by discretizing a domain spatially using tree-structure grid (quad-tree and nona-tree grids). Developed simulation code is compared with the conventional tsunami simulation code. The simulation results for the same bathymetry and source data show good agreement. The number of grid cell of the adaptive mesh model is about half that of a uniform mesh model. And the calculation time of the developed code is shorter than that of the conventional code with a uniform grid by approximately 10%. The parallelization efficiency of the developed code adapted for the non-linear long-wave theory applied to the nona-tree grid model with four consolidation level is around 70% in the case of 24 parallel-running tasks.
