Calculation of the displacement

• Coil elements are treated as a slender beam with
  rectangular cross sections
• Upper part is calculated (red part in the left
  figure)
• Fixed rigid boundary at the left bottom,
  symmetric connection to the lower part at the
  equator
• Spring connections at CS Top, TF joint/FRP and
  ABS/SUS.
