    A voxelization based mesh generation algorithm for numerical models used in foundry engineering
    (2012) Szucki, Michał; Suchy, Józef Szczepan
    The aim of this study is the adaptation of the voxelization algorithm for the generation of regular computational meshes used in numerical models. The authors concentrate on solutions, which can be applied in a computer modeling of phenomena occurring in the foundry industry. The presented mesh generation process is the STL files based. This file format is generally used in the commercial simulation software. The basic voxelization algorithm extended with such functions as: the input data correctness control (virtual geometry), the formation of meshes consisting of several subdomains corresponding to individual elements of the foundry technology (mould, casting, core, feeder etc.) and the possibility of the mesh local refinement (adaptive grids), is presented in the hereby paper. The described solution is characterized by high efficiency and when combined with the proper numerical model can be successfully implemented in problems related to computer simulation of foundry processes.

    When calculating arrival times between multiple points the problem that can arise is the proper location these points one the map. Grid points for which calculations are to be done may form a regular, orthogonal grid or may be located at different, irregular densities. In this paper the algorithm for creating irregular grid points based on regular grid will be presented. Both representations will be analyzed and compared. It will be evaluated whether the points of such grids are representative points for a given problem.
