Abstract

Some key technologies for numerical simulation in casting were analyzed

and the SIMU-CAST software was developed.The software has the function of solidification field and prediction of shrinkage porosities during casting process based on FEM method

in which non-leaner features of materials and boundary conditions as well as latent heat were taken into account.The simulated results from SIMUCAST were verified by ProCAST and experiment.The results reveal that the developed software exhibits the high accuracy in calculation and simulation

meanwhile

prediction of shrinkage porosities is well agreement with the practical ones

meeting the industrial application.
