In this paper a method is presented to generate uniform hexahedral meshes automatically. In this method, a solid model with complex geometry is decomposed into swept volumes with simpler geometry. A sweepable face on the solid model is selected as the generator face to generate a swept volume. Each generator face is specified with node density and a quadrilateral mesh is generated from it. Then, the mesh is swept into a hexahedral mesh of the swept volume. Finally, all hexahedral meshes of swept volumes are recomposed into a hexahedral mesh of the original solid model.
