So far Computational Fluid Dynamics (CFD) has focused on grid‐based methods, where two different frames are usually considered for describing the physical governing equations, namely: the Eulerian and the Lagrangian description (Table 1).
The development of mesh free methods offers a reliable approach to tackle the simulation of such difficult problems.
In numeric simulation, larger resolution will help reduce errors, which are inevitable in floating point calculation; larger problem domain often means more analogy with realistic experiment and better simulation result.
For this reason, numerical simulation about tsunami wave from submarine slide are very necessary.
