A software code based on SOLA-VOF algorithm is developed for numerical simulation of mold filling of semi-solid metals.The semi-solid mould filling processes of A356 and AZ91D are studied based on the Power-Law viscosity model and constant viscosity model,respectively.Test molds with different thicknesses and shapes were chosen to validate the software code.The simulated mould filling sequence shows a good agreement with the experimental results.The viscosity distribution is also calculated and plotted with a post-processor.The results show that the software code can offer an effective understanding for semi-solid mold filling processes.
