Filling is mainly sequential from bottom to top, which encourages a good positive temperature distribution. Overall, the solidification pattern is good with solidification proceeding from bottom to top of casting. The only exceptions are the (4) bosses which create isolated hot spots that lead to the potential of shrinkage formation during solidification. This might be masked by running with a higher gas content or by chilling, or by providing some sort of feed metal (pads and risers) at each of these locations.
