					Features:
1. 2D structural analysis (plane stress)
2. Static analysis
3. Quarter symmetric
4. SI units
5. Only the yoke is modeled
6. Material properties are at 4 K
  · SS304: Poisson’s ratio 0.279, Young’s modulus 210.0E9 Pa
 · Iron yoke: Poisson’s ratio 0.284, Young’s modulus 224.02E9 Pa,
modeled as a solid material (not as laminations)
7. Loading conditions: 5.5 MPa applied vertically, 3.0 MPa applied
horizontally (see geometry plot)
