Based on traditional orthogonal grid decomposition algorithms, this paper studies the decomposition algorithm of boundary cut grid and develops the corresponding calculation program by ray method. It carries out grid decomposition of actual castings, the results show that compared to zigzag grid, boundary cut grid has good adaptability to castings with curved surface and can reflect surface features of castings, thereby laying a foundation for accurately solving physical fields, such as flow field and temperature field, etc.
