Problem Type
Axisymmetric multiphysics problem of DC magnetics coupled to Stress analysis.
Inner radius R1 = 1 cm, outer radius R2 = 2 cm.
Current density j = 4 MA/m²,
Coil Young modulus E = 107.5 GPa, Poisson ratio ν = 0.33.
Calculate the mechanical stress distribution.
In this example, we ignore the end effects and model the central part of the solenoid only.
