A method for simulating the filling and solidification processes was developed using the numerical particle method of smoothed particle hydrodynamics (SPH). First, a specific algorism based on SPH was designed to simulate the filling and solidification of casting alloy. Then it was employed to simulate JIS-ADC12 conical molds, focusing on the formation of defects such as shrinkage cavity and porosity. The results showed that : 1) the SPH method based on the algorism can clearly simulate the formation of shrinkage cavities formed in the JIS-ADC12 conical mold, and 2) the method using the simulated gas particles is able to predict the location of porosities in casting materials.
