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.
