The hexahedral mesh is one of the most important tools in three-dimensional FEA because it can increase the accuracy of the solution and decrease the overall element count. In the present study, a general framework of hexahedral mesh generation of metal forming simulation based on master grid approach is presented, which includes identification of CAD or remeshing model, generation of core mesh, boundary mesh fitting, surface element layer (SEL) generation and mesh smoothing. The results clearly indicated that the algorithms proposed in this study is simple in principal, robustness in programming and can generate high-quality hexahedral mesh. Meanwhile, some important issues about this algorithm are discussed.
