Abstract
It is well known that calculated results of pressure by MPS method has an unnatural oscillation with high frequency. To reduce the oscillation, a numerical method is developed by introducing an auxiliary computation procedure subordinated to MPS method. There are two characteristic points in the proposed computation scheme. One is the source term of pressure Poisson's equation. The other is the ALE procedure in the velocity-pressure coupling scheme. The calculated pressure is improved by the present method.
