Hexahedral mesh construction for a domain with three materials. (a) - surface quadrilateral mesh; (b) - surface mesh after quality improvement with geometric flow (100 steps with step length 0.01); (c) - one cross-section of the original hexahedral mesh; (d) - one cross-section of the improved hexahedral mesh.
