Objective To study high-quality and high efficient meshing methods for skeleton. Methods Based on characteristics of bone structure, the mesh generation technology of computational fluid dynamics (CFD) was applied in mesh generation for bone biomechanics. Hexahedron elements and tetrahedron elements were used to simulate cortical bone and cancellous bone, respectively. Results By using CFD mesh generation technology, high-quality hexahedral elements could be obtained, the structure characteristics of skeleton could be preferably simulated, and computer automatic meshing could be implemented. The amount of time for meshing bones by the new method was only about 1/5 of that by the traditional method, and the calculation results obtained from the finite element model were basically consistent with the results from the cadaver experiment. Conclusions The CFD mesh generation technology can be applied in the field of bone biomechanics, which provides an effective approach to reconstruct complex human skeleton.
