Mould filling is an important part of the casting process and cannot be neglected if an accurate analysis of casting solidification is desired. A numerical technique has been developed to model heat transfer and solidification of metal during and after the filling of a mould. The simulation incorporates a macroscopic fluid flow and heat transfer analysis from the initial stages of filling until filling is completed. Solidification is accounted for as is the temperature dependence of the fluid velocity as solid forms at the mould walls. The computing technique is based on the SOLA-VOF finite difference method for two dimensional mould geometries. Heat conduction and energy transport are modelled using coupled heat conduction-heat convection equations. Limitations of the computing technique are demonstrated.
