Because spring's ground coils exhibit strong geometric distortions, existing automatic approaches have been unable to produce consistent, high-quality hexahedral meshes. Our method morphs a structured O-grid along the evolving cross-section shape, preserving topology and nodal continuity. The resulting hexahedral meshes maintain high quality metrics and enable accurate finite element simulations that capture both global stiffness and local nonlinear effects from end-coil imperfections. This constitutes the first reliable and high-fidelity numerical reconstruction of ground-end springs.
