主 题：Metal casting simulation solidification pattern volume segmentation feeder design.
摘 要：In the process of interpreting simulation results,new post-processing techniques are *** work presents a post-processing method that analyzes the solidification pattern formed by simulation of the solidification process of molten metal in a mold to produce shaped *** generally involve numerical solutions of differential equations which are discretized by dividing the three-dimensional computational domain into small finite volume elements using a 3D *** locations of the grid points and values of the solidification time at these locations are used to divide the spatial data into 3D sections such that starting from a hotspot location within the section that has high solidification time,there is a gradient outwards with lower values of solidification *** section is assumed to be fed by one or more feeders that must freeze only after the section has solidified *** volume of a feeder can be determined from the volume of the section it is supposed to *** volume and surface area of sections are determined approximately to calculate feeder size and *** post-processing algorithm is a simulation-based quantitative approach to feeder design which in conventional foundry practice has been more of an art than *** is also general enough for use in other 3D segmentation applications.
