| 英文摘要 | In this paper, we present a new cellular automata model for modeling seismic waves, the PLSVL model (Phononic lattice solid with various grids length). In this model, wt: change the grid length according to the wave velocity, and the particles move one grid length at a time step in all lattice grids. The lattice Boltzmann equation and its macroscopic limit for PLASVL are derived. At macroscopic limit, the Boltzmann equation and Its scattering term of PLSVL model is the same as of PLS model, and they have the same properties, so we can derive wave equation from the Boltzmann equation of PLSVL. There's no error in the transportation step inside one lattice grid; time increasing can not accumulate the error generated at the interface. We also give a numerical example of the PLSVL model. |
