Comparison of SPH simulations of high pressure die casting with the experiments and VOF simulations of Schmid and Klein

SPH simulations of die filling for three geometries previously studied by Schmid and Klein are compared to their experimental and numerical results. The agreement with experiment for both numerical methods is very good, but the SPH solutions tend to capture free surface and void shapes modestly better than the VOF and also predict small scale structure better. These result from the Lagrangian nature of SPH and the superior mass conservation properties of this particle method.
