| Abstract: |
| In this study,a set of particle interaction models are proposed for the moving particle semi-implicit (MPS) method.Discretization of operators are obtained using Taylor series in the particle's local coordinates.By this approach,the set of MPS models with a better precision can be gotten when MPS particles are randomly positioned or near to boundaries.Three typical tests are performed to verify the modified method and related discretization schemes.Furthermore,the new MPS method is implemented to simulate the broken-dam phenomenon. |
