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 E9 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) 8. Boundary conditions: symmetry conditions on both horizontal and vertical geometric boundaries
