Abstract
The moving particle semi-implicit method (MPS) was used to simulate the typical free surface problem, 2D dam break problem, and the effect of initial particle configuration on the simulated results was analyzed. It is found that the reasonable results can not be achieved for too large or too small particle distance. The comparison of the results by MPS, SPH or VOF with the experimental data shows that the result by MPS is between those by VOF and by SPH. Without the consideration of viscosity, the result by MPS is closer to the experiment than that by VOF. However, the result by MPS with the consideration of viscosity may be similar to that by SPH.
